How can I iterate SharePoint lists and subsites from a C# program? Is the SharePoint.dll from a SharePoint installation required for this, or is there a "Sharepoint client" dll available for remotely accessing that data?
Use the Sharepoint web services; in particular the Webs and Lists webservices do what you ask.
For Sharepoint 2007:
http://msdn.microsoft.com/en-us/library/bb862916(v=office.12).aspx
For Sharepoint 2007 you will need to access the web services. In Sharepoint 2010, there is a sharepoint client object model.

I happen to be dealing with this very thing now... this works. I've dumbed down the code a bit to focus on just the mechanics. It's rough around the edges, but hopefully you get the idea. It's working for me.
Also, be sure to set up a web reference using the URL of your Sharepoint site. Use that as your "web reference" below.
private <web reference> _Service;
private String _ListGuid, _ViewGuid;
private Initialize()
{
_Service = new <web reference>.Lists();
_Service.Credentials = System.Net.CredentialCache.DefaultCredentials;
_Service.Url = "https://sharepointsite/_vti_bin/lists.asmx";
}
private String SpFieldName(String FieldName, Boolean Prefix)
{
return String.Format("{0}{1}", Prefix ? "ows_" : null,
FieldName.Replace(" ", "_x0020_"));
}
private String GetFieldValue(XmlAttributeCollection AttributesList,
String AttributeName)
{
AttributeName = SpFieldName(AttributeName, true);
return AttributesList[AttributeName] == null ?
null : return AttributesList[AttributeName].Value;
}
public void GetList()
{
string rowLimit = "2000"; // or whatever
System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
System.Xml.XmlElement query = xmlDoc.CreateElement("Query");
System.Xml.XmlElement viewFields = xmlDoc.CreateElement("ViewFields");
System.Xml.XmlElement queryOptions =
xmlDoc.CreateElement("QueryOptions");
queryOptions.InnerXml = "";
System.Xml.XmlNode nodes = _Service.GetListItems(_ListGuid, _ViewGuid,
query, viewFields, rowLimit, null, null);
foreach (System.Xml.XmlNode node in nodes)
{
if (node.Name.Equals("rs:data"))
{
for (int i = 0; i < node.ChildNodes.Count; i++)
{
if (node.ChildNodes[i].Name.Equals("z:row"))
{
XmlAttributeCollection att =
node.ChildNodes[i].Attributes;
String title = GetFieldValue("Title");
String partNumber = GetFieldValue("Part Number");
}
}
}
}
}
}
Also, the SpFieldName method is not iron-clad. It's just a good guess, for most field names in a list. This, unfortunately, is a journey of discovery. You need to expose the XML to find the actual field names if they don't match.
Good hunting.

So i've been trying to get a program working where I get info from google finance regarding different stock stats. So far I have not been able to get information out of spans. As of now I have hardcoded direct access to the apple stock.
Link to Apple stock: https://www.google.com/finance?q=NASDAQ%3AAAPL&ei=NgItWIG1GIftsAHCn4zIAg
What i can't understand is that I receive correct output when I trying it in the chrome console with the following command:
$x("//*[#id=\"appbar\"]//div//div//div//span");
This is my current code in Visual studio 2015 with Html Agility Pack installed(I suspect a fault in currDocNodeCompanyName):
class StockDataAccess
{
HtmlWeb web= new HtmlWeb();
private List<string> testList;
public void FindStock()
{
var histDoc = web.Load("https://www.google.com/finance/historical?q=NASDAQ%3AAAPL&ei=q9IsWNm4KZXjsAG-4I7oCA.html");
var histDocNode = histDoc.DocumentNode.SelectNodes("//*[#id=\"prices\"]//table//tr//td");
var currDoc = web.Load("https://www.google.com/finance?q=NASDAQ%3AAAPL&ei=CdcsWMjNCIe0swGd3oaYBA.html");
var currDocNodeCurrency = currDoc.DocumentNode.SelectNodes("//*[#id=\"ref_22144_elt\"]//div//div");
var currDocNodeCompanyName = currDoc.DocumentNode.SelectNodes("//*[#id=\"appbar\"]//div//div//div//span");
var histDocText = histDocNode.Select(node => node.InnerText);
var currDocCurrencyText = currDocNodeCurrency.Select(node => node.InnerText);
var currDocCompanyName = currDocNodeCompanyName.Select(node => node.InnerText);
List<String> result = new List<string>(histDocText.Take(6));
result.Add(currDocCurrencyText.First());
result.Add(currDocCompanyName.Take(2).ToString());
testList = result;
}
public List<String> ReturnStock()
{
return testList;
}
}
I have been trying the Xpath expression [text] and received an output that i can work with when using the chrome console but not in VS. I have also been experimenting with a foreach-loop, a few suggested it to others.
class StockDataAccess
{
HtmlWeb web= new HtmlWeb();
private List<string> testList;
public void FindStock()
{
///same as before
var currDoc = web.Load("https://www.google.com/finance?q=NASDAQ%3AAAPL&ei=CdcsWMjNCIe0swGd3oaYBA.html");
HtmlNodeCollection currDocNodeCompanyName = currDoc.DocumentNode.SelectNodes("//*[#id=\"appbar\"]//div//div//div//span");
///Same as before
List <string> blaList = new List<string>();
foreach (HtmlNode x in currDocNodeCompanyName)
{
blaList.Add(x.InnerText);
}
List<String> result = new List<string>(histDocText.Take(6));
result.Add(currDocCurrencyText.First());
result.Add(blaList[1]);
result.Add(blaList[2]);
testList = result;
}
public List<String> ReturnStock()
{
return testList;
}
}
I would really appreciate if anyone could point me in the right direction.
If you check the contents of currDoc.DocumentNode.InnerHtml you will notice that there is no element with the id "appbar", therefore the result is correct, since the xpath doesn't return anything.
I suspect that the html element you're trying to find is generated by a script (js for example), and that explains why you can see it on the browser and not on the HtmlDocument object, since HtmlAgilityPack does not render scripts, it only download and parse the raw source code.
Hi I am trying to parse some xml from a weird xml document developed by icalander. I have been having a lot of trouble just parsing the data, but thanks to the help of people from stackoverflow I have been able to parse the data. Now I need some help parsing between the nodes. Here is a link to the xml file I am parsing from (http://datastore.unm.edu/events/events.xml)
I am using the pivotapp model from Visual Studio 2010 to create this app. In the MainViewModel.cs section I am modifying the following code in hopes that the tag will print out in place of "LineOne" (code listed below). For example, from the xml file linked above, I would like LineOne = Lobo's Got Talent.
I need help figuring out the best method to achieve this, I will need LineTwo to contain the date and time, and LineThree to contain the description.
Thank you for your time and help, it has been greatly appreciated!
public void LoadData()
{
var webClient = new WebClient();
webClient.OpenReadAsync(new Uri("http://datastore.unm.edu/events/events.xml"));
webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(webClient_OpenReadCompleted);
}
public void webClient_OpenReadCompleted(object sender,
OpenReadCompletedEventArgs e)
{
XDocument unmXdoc = XDocument.Load(e.Result, LoadOptions.None);
this.Items.Add(new ItemViewModel() { LineOne = unmXdoc.ToString(),
LineTwo = "", LineThree = "" });
}
Thank you for looking and helping!
The xml is fine, I think you are running into a namespace issue here, you have two options, strip the namespace of the xml file if you are sure you do not need it. The preferred option is to work with the namespace and specify it for the fully qualified element names. see Here
private readonly XNamespace dataNamspace = "urn:ietf:params:xml:ns:icalendar-2.0";
public void webClient_OpenReadCompleted(object sender,
OpenReadCompletedEventArgs e)
{
XDocument unmXdoc = XDocument.Load(e.Result, LoadOptions.None);
this.Items = from p in unmXdoc.Descendants(dataNamspace + "vevent").Elements(dataNamspace + "properties")
select new ItemViewModel
{
LineOne = this.GetElementValue(p, "summary"),
LineTwo = this.GetElementValue(p, "description"),
LineThree = this.GetElementValue(p, "categories"),
};
lstData.ItemsSource = this.Items;
}
private string GetElementValue(XElement element, string fieldName)
{
var childElement = element.Element(dataNamspace + fieldName);
return childElement != null ? childElement.Value : String.Empty;
}
Hello i need your super help.
Im not soo skilled in C# and i stack for about 6 hours on this. So please if anyone know help me . Thx
I have Xml like this
<COREBASE>
<AGENT>
<AGENT_INDEX>1</AGENT_INDEX>
<AGENT_PORTER_INDEX>
</AGENT_PORTER_INDEX>
<AGENT_NAME>John</AGENT_NAME>
<AGENT_SURNAME>Smith</AGENT_SURNAME>
<AGENT_MOBILE_NUMBER>777777777</AGENT_MOBILE_NUMBER>
</AGENT>
<AGENT>
<AGENT_INDEX>2</AGENT_INDEX>
<AGENT_PORTER_INDEX>1
</AGENT_PORTER_INDEX>
<AGENT_NAME>Charles</AGENT_NAME>
<AGENT_SURNAME>Bukowski</AGENT_SURNAME>
<AGENT_MOBILE_NUMBER>99999999</AGENT_MOBILE_NUMBER>
</AGENT>
</COREBASE>
And I need to select agent by index in windows forms combo box and than edit and save his attributes to xml. I found how to edit and save it but i dont know why but its saved to the first agent and overwrite his attributes in XML but not in the selected one.. :-(
Plese i will be glad for any help
private void buttonEditAgent_Click(object sender, EventArgs e)
{
XmlDocument AgentBaseEdit = new XmlDocument();
AgentBaseEdit.Load("AgentBase.xml");
XDocument AgentBase = XDocument.Load("AgentBase.xml");
var all = from a in AgentBase.Descendants("AGENT")
select new
{
agentI = a.Element("AGENT_INDEX").Value,
porterI = a.Element("AGENT_PORTER_INDEX").Value,
agentN = a.Element("AGENT_NAME").Value,
agentS = a.Element("AGENT_SURNAME").Value,
agentM = a.Element("AGENT_MOBILE_NUMBER").Value,
};
foreach (var a in all)
{
if ("" == textBoxEditAgentIndex.Text.ToString())
{
MessageBox.Show("You must fill Agent Index field !!", "WARNING");
}
else
{
// AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_INDEX").InnerText == textBoxEditAgentIndex.Text
if (a.agentI == textBoxEditAgentIndex.Text.ToString())
{
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_INDEX").InnerText = textBoxEditAgentIndex.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_PORTER_INDEX").InnerText = textBoxEditAgentPorterIndex.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_NAME").InnerText = textBoxEditAgentName.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_SURNAME").InnerText = textBoxEditAgentSurname.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_MOBILE_NUMBER").InnerText = textBoxEditAgentMobile.Text;
AgentBaseEdit.Save("AgentBase.xml");
ClearEditAgentTxtBoxes();
}
}
}
}
Am i on the right way but i dont see the doors or i am totaly wrong ? Thx all. Miko
OK i tried it this way but it didnt changed the inner text
string agentIndex = comboBoxEditAgentI.SelectedItem.ToString();
XmlDocument AgentBaseEdit = new XmlDocument();
AgentBaseEdit.Load("AgentBase.xml");
XDocument AgentBase = XDocument.Load("AgentBase.xml");
var xElemAgent = AgentBase.Descendants("AGENT")
.First(a => a.Element("AGENT_INDEX").Value == agentIndex);
xElemAgent.Element("AGENT_MOBILE_NUMBER").Value = textBoxEditAgentMobile.Text;
xElemAgent.Element("AGENT_SURNAME").Value = textBoxEditAgentSurname.Text;
AgentBaseEdit.Save("AgentBase.xml");
It would be easier if you use Linq2Xml.
int agentIndex = 2;
XDocument xDoc = XDocument.Load(filename);
var xElemAgent = xDoc.Descendants("AGENT")
.First(a => a.Element("AGENT_INDEX").Value == agentIndex.ToString());
//or
//var xElemAgent = xDoc.XPathSelectElement(String.Format("//AGENT[AGENT_INDEX='{0}']",agentIndex));
xElemAgent.Element("AGENT_MOBILE_NUMBER").Value = "5555555";
xDoc.Save(fileName)
PS: namespaces: System.Xml.XPath System.Xml.Linq
It does not work, because you are selecting the first agent explicitly with in each loop
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/...")
But you can do it easier by reading and changing withing the same xml document. I'm only changing the agent name and replacing it with "test 1", "test 2", ...
XDocument AgentBase = XDocument.Load("AgentBase.xml");
int i = 0;
foreach (XElement el in AgentBase.Descendants("AGENT")) {
el.Element("AGENT_NAME").Value = "test " + ++i;
// ...
}
AgentBase.Save("AgentBase.xml");
UPDATE
However, I'm suggesting you to separate the logic involving the XML handling from the form. Start by creating an Agent class
public class Agent
{
public string Index { get; set; }
public string PorterIndex { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string Mobile { get; set; }
}
Then create an interface defining the needed functionality for an agent repository. The advantage of this interface is that it will make it easier later to switch to another kind of repository like a relational database.
public interface IAgentRepository
{
IList<Agent> LoadAgents();
void Save(IEnumerable<Agent> agents);
}
Then create a class that handles the agents. Here is a suggestion:
public class AgentXmlRepository : IAgentRepository
{
private string _xmlAgentsFile;
public AgentXmlRepository(string xmlAgentsFile)
{
_xmlAgentsFile = xmlAgentsFile;
}
public IList<Agent> LoadAgents()
{
XDocument AgentBase = XDocument.Load(_xmlAgentsFile);
var agents = new List<Agent>();
foreach (XElement el in AgentBase.Descendants("AGENT")) {
var agent = new Agent {
Index = el.Element("AGENT_INDEX").Value,
PorterIndex = el.Element("AGENT_PORTER_INDEX").Value,
Name = el.Element("AGENT_NAME").Value,
Surname = el.Element("AGENT_SURNAME").Value,
Mobile = el.Element("AGENT_MOBILE_NUMBER").Value
};
agents.Add(agent);
}
return agents;
}
public void Save(IEnumerable<Agent> agents)
{
var xDocument = new XDocument(
new XDeclaration("1.0", "utf-8", null),
new XElement("COREBASE",
agents.Select(a =>
new XElement("AGENT",
new XElement("AGENT_INDEX", a.Index),
new XElement("AGENT_PORTER_INDEX", a.PorterIndex),
new XElement("AGENT_NAME", a.Name),
new XElement("AGENT_SURNAME", a.Surname),
new XElement("AGENT_MOBILE_NUMBER", a.Mobile)
)
)
)
);
xDocument.Save(_xmlAgentsFile);
}
}
The form can now concentrate on the editing logic. The form does not even need to know what kind of repository to use if you inject the repository in the form constructor (of cause the form constructor must declare a parameter of type IAgentRepository):
var myAgentForm = new AgentForm(new AgentXmlRepository("AgentBase.xml"));
myAgentForm.Show();
UPDATE #2
Note that you cannot change a single item within an XML file. You must load all the agents, make an edit and then rewrite the whole file, even if you edited only one agent.
To do this, you can use my LoadAgents method, then pick an agent from the returned list, edit the agent and finally write the agents list back to the file with my Save method. You can find an agent in the list with LINQ:
Agent a = agents
.Where(a => a.Index == x)
.FirstOrDefault();
This returns null if an agent with the required index does not exist. Since Agent is a reference type, you don’t have to write it back to the list. The list is keeping a reference to the same agent as the variable a.
I have looked all over for this. It could be me just typing the wrong thing in search I'm not sure. So, if you know a good tutorial or example of this please share. I'm trying to learn.
I have a C# Windows Form app I'm working on. I have information (movies in this case) saved in an XML file. I saved the xml file like this.
//Now we add new movie.
XmlElement nodRoot = doc.DocumentElement;
string allMyChildren = nodRoot.InnerText;
string capitalized = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(movieEditNameTextbox.Text);
int indexLookForNewMake = allMyChildren.IndexOf(capitalized);
if (indexLookForNewMake >= 0)
{
MessageBox.Show("Movie is already saved.", "Error");
}
else
{
XmlElement el = doc.CreateElement("Name");
el.InnerText = capitalized;
doc.DocumentElement.AppendChild(el);
//Check if Year is really a Number.
if (movieEditYearTextbox.Text.All(Char.IsDigit))
{
//Remove ' cause it gives errors.
string capitalizedFixed = capitalized.Replace("'", "");
string capitalizedFinalFixed = capitalizedFixed.Replace("\"", "");
//Assign Attribute to each New one.
el.SetAttribute("Name", capitalizedFinalFixed);
el.SetAttribute("Type", movieEditTypeDropdown.Text);
el.SetAttribute("Year", movieEditYearTextbox.Text);
//Reset all fields, they don't need data now.
movieEditNameTextbox.Text = "";
movieEditYearTextbox.Text = "";
movieEditTypeDropdown.SelectedIndex = -1;
removeMovieTextbox.Text = "";
doc.Save("movie.xml");
label4.Text = "Movie Has been Edited";
loadXml();
}
else
{
//Error out. Year not a Number
MessageBox.Show("Check movie year. Seems it isn't a number.", "Error");
}
}
That all works fine. Now what I'm trying to do is make it where you can choose a directory, and it search the directory and sub directories and get file names and save them into the XML file.
I used this to try to accomplish this. It does pull the list. But it doesn't save it. It don't save the new information.
I can't use LINQ as it cause a confliction for some reason with other code.
DirectoryInfo dirCustom = new DirectoryInfo(#"D:\Video");
FileInfo[] filCustom;
filCustom = dirCustom.GetFiles("*",SearchOption.AllDirectories);
//Open XML File.
XmlDocument doc = new XmlDocument();
doc.Load("movie.xml");
XmlElement el = doc.CreateElement("Name");
string fulCustoms = filCustom.ToString();
foreach (FileInfo filFile in filCustom)
{
string capitalized = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(filFile.Name);
string capitalizedFixed = capitalized.Replace("\"", "");
el.SetAttribute("Name", capitalizedFixed);
el.SetAttribute("Type", "EDIT TYPE");
el.SetAttribute("Year", "EDIT YEAR");
richTextBox1.AppendText(capitalizedFixed + "\r\n");
}
doc.Save("movie.xml");
label4.Text = "Movie Has been Edited";
loadXml();
Now, the richTextBox does display the information correctly but it don't save it.
The loadXml() is just my noobish way to refresh the datagridview.
I'm completely lost and don't know where to turn to. I know my coding is probarely horrible, lol. I'm new to this. This is my first more complex application I have worked on.
I can't think of anymore information that would help you understand what I mean. I hope you do.
Thank you so much for your help.
Not sure exactly what your LoadXML() method does but my only piece of advise with your issue is to change the way you are implementing this functionality.
Create an object called Movie
public class Movie
{
public Movie() {}
public String Title { get; set; }
blah... blah...
}
Then create a MovieList
public class MovieList : List<Movie> { }
Then implement the following 2 methods inside the MovieList.
public static void Serialize(String path, MovieList movieList)
{
XmlSerializer serializer = new XmlSerializer(typeof(MovieList));
using (StreamWriter streamWriter = new StreamWriter(path))
{
serializer.Serialize(streamWriter, movieList);
}
}
public static MovieList Deserialize(String path)
{
XmlSerializer serializer = new XmlSerializer(typeof(MovieList));
using (StreamReader streamReader = new StreamReader(path))
{
return (MovieList) serializer.Deserialize(streamReader);
}
}
Thats it... You now have your object serialized and you can retrieve the data to populate through binding or whatever other methods you choose.
I am playing around with a SharePoint server and I am trying to programmatically add a service request to microsoft's call center application template. So far, I have had pretty good success. I can add a call for a specified customer and assign a specific support tech:
private enum FieldNames
{
[EnumExtension.Value("Service Request")]
ServiceRequest,
[EnumExtension.Value("Customer")]
Customer,
[EnumExtension.Value("Service Representative")]
ServiceRepresentative,
[EnumExtension.Value("Assigned To")]
AssignedTo,
[EnumExtension.Value("Software")]
Software,
[EnumExtension.Value("Category")]
Category
}
private void CreateServiceCall(string serviceCallTitle, string customerName, string serviceRep)
{
SPSite allSites = new SPSite(siteURL);
SPWeb site = allSites.AllWebs[siteName];
SPListItemCollection requestsList = site.Lists[serviceRequests].Items;
SPListItem item = requestsList.Add();
SPFieldLookup customerLookup = item.Fields[FieldNames.Customer.Value()] as SPFieldLookup;
item[FieldNames.ServiceRequest.Value()] = serviceCallTitle;
if (customerLookup != null)
{
using (SPWeb lookupWeb = allSites.OpenWeb(customerLookup.LookupWebId))
{
SPList lookupList = lookupWeb.Lists.GetList(new Guid(customerLookup.LookupList), false);
foreach (SPListItem listItem in lookupList.Items)
{
if (listItem[customerLookup.LookupField].ToString() != customerName) continue;
item[FieldNames.Customer.Value()] = new SPFieldLookupValue(listItem.ID, customerName);
break;
}
}
}
SPUserCollection userCollection = site.SiteUsers;
if (userCollection != null)
{
foreach (SPUser user in userCollection)
{
if (user.Name != serviceRep) continue;
item[FieldNames.AssignedTo.Value()] = user;
break;
}
}
item.Update();
site.Close();
allSites.Close();
}
I added two custom columns (category, software) to the default list:
I populated both of these columns inside of SharePoint, now I want to retrieve that data so I can use it in the code snippet I posted to assign the proper category/software etc to the call. I have not been able to get the list in the code, I have tried using a item["Software"], site.Lists["Software"] and a couple of others, but so far all I have come up is null.
Can anyone point me in the right direction for this? Thanks!
SPFieldMultiChoice and related fields have a Choices property:
SPFieldMultiChoice software = item.Fields[FieldNames.Software.Value()] as SPFieldMultiChoice;
StringCollection softwareChoices = software.Choices;
If you need to set a value on the field, use the SPFieldMultiChoiceValue type:
SPFieldMultiChoiceValue values = new SPFieldMultiChoiceValue();
values.Add("Choice 1");
values.Add("Choice 2");
item[FieldNames.Software.Value()] = values;
