I have this code block in c# vs 2013

inCartera["Fin"] = cl["FechaAsignacionCodigo"];
inCartera["EstadoFinal"] = "Cliente Creado";
queryService.createItem("indicators", inCartera);
}
}
}
}
}
What it does is consult the clients list and then with the if I tell it which one it inserts in the list of indicators.
The problem is that the list of clients has more than 2,000 records and how is online sharepoint I get an error
of information:
An operation that is prohibited was attempted because it exceeds the list view threshold applied by the administrator
How can I consult the list so that it triagates all the data and with the the if filter?

I want to display files from a sharepoint folder that were modified by username. please help me for this. Also tell me how to show this file with sorting order by datetime.
I tried using
docName.Add(file.ModifiedBy);
property but its not available, here is the code:
public List<string> getFiles(ClientContext CContext,string INVOICENO)
{
List list = CContext.Web.Lists.GetByTitle("Documents");
CContext.Load(list);
CContext.Load(list.RootFolder);
CContext.Load(list.RootFolder.Folders);
CContext.Load(list.RootFolder.Files);
CContext.ExecuteQuery();
FolderCollection fcol = list.RootFolder.Folders;
List<string> docName = new List<string>();
foreach (Folder f in fcol)
{
if(INVOICENO==null)
{
INVOICENO = "";
}
string foldername = INVOICENO.ToString();
if (f.Name == foldername)
{
CContext.Load(f.Files);
CContext.ExecuteQuery();
FileCollection fileCol = f.Files;
foreach (File file in fileCol)
{
docName.Add(file.Name);
docName.Add(file.TimeLastModified.ToShortDateString());
}
}
}
return docName.ToList();
}
According to my testing and research, you can use CAML Query to display the files modified by the username from the SharePoint folder.
Here is an example you can refer to:(sorted by modification time in ascending order)
static void Main(string[] args)
{
var clientContext = GetonlineContext();
Web site = clientContext.Web;
List list = clientContext.Web.Lists.GetByTitle("Library Name");
CamlQuery query = new CamlQuery();
query.ViewXml = "<View><Query><Where><Eq><FieldRef Name='Editor' /><Value Type='User'>UserName</Value></Eq></Where><OrderBy><FieldRef Name='Modified' Ascending='True' /></OrderBy></Query><ViewFields /><QueryOptions /></View>";
ListItemCollection collListItem = list.GetItems(query);
clientContext.Load(collListItem);
clientContext.ExecuteQuery();
foreach (ListItem item in collListItem)
{
Debug.WriteLine("Name:"+item["FileLeafRef"]+"\n"+"Modified"+item["Modified"]);
}
clientContext.ExecuteQuery();
}
I am reading the sharepoint online list item using SharePointPnPCoreOnline as below. But it doesn't retrieve any items. Data count is always zero. Please let me know what I am missing.
using Microsoft.SharePoint.Client;
using OfficeDevPnP.Core;
using System;
string siteUrl = "****";
string clientId = "*****";
string clientSecret = "******";
using (var clientContext = new AuthenticationManager().GetAppOnlyAuthenticatedContext(siteUrl, clientId, clientSecret))
{
clientContext.Load(clientContext.Web, p => p.Title);
clientContext.ExecuteQuery();
Console.WriteLine(clientContext.Web.Title);
List sourceList = clientContext.Web.Lists.GetByTitle("MyList");
clientContext.Load(sourceList);
clientContext.ExecuteQuery();
Console.WriteLine("GUID of List: " + sourceList.Id);
CamlQuery camlQuery = new CamlQuery();
ListItemCollection listItems = sourceList.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();
Console.WriteLine("Total Item Count of List: " + listItems.Count);
foreach (ListItem listItem in listItems)
{
foreach (var field in listItem.FieldValues)
{
Console.WriteLine("{0} : {1}", field.Key, field.Value);
}
}
}
Note: when I try the same set of code with username and password,I am able to retreive the items in the list.
And the Client ID and Secret are created in Azure.
Hi i try to write a little application for sharepoint 2013 where we can backup our projects on an SQL Server. Now i try to loop trough all projects on sharepoint so i can get the content of the fields. Like country = austria.
I tried to follow this guide but had no luck: https://msdn.microsoft.com/en-us/library/office/fp179912.aspx
Here is that what i got:
//Loads only a Projeclist from sharepoint
public SPpowerPlantList loadProjectFromSharePoint()
{
SPpowerPlantList pplist = new SPpowerPlantList();
ClientContext context = new ClientContext(powerPlantSite);
Web web = context.Web;
context.Load(web.Lists);
context.ExecuteQuery();
foreach (List list in web.Lists)
{
SPpowerPlant pp = new SPpowerPlant();
//Stuff like this one should work but dont....
pp.country = list.country
}
return pplist;
}
Any advice would be great and sorry for my english
EDIT: SPpowerPlantList should be a List of all Projects of the Project-List from Sharepoint. And the loadProjectsFromSharepoint is supposed to get a list of Projects wich the i can start to add the values to the sql Server. Stuff like SQL Table value = Sharepoint Field Value.
EDIT2 So the access to the files now work for a few fields but know i get an The property or field has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested exeption.
Here is the new code: (some fields work like currency)
//Loads only a Projeclist from sharepoint
public SPpowerPlantList loadProjectFromSharePoint()
{
SPpowerPlantList powerPlantList = new SPpowerPlantList();
ClientContext context = new ClientContext(powerPlantSite);
List powerPlantsList = context.Web.Lists.GetByTitle("Power Plants");
CamlQuery query = CamlQuery.CreateAllItemsQuery();
query.ViewXml = #"<View><Query> </Query></View>";
ListItemCollection items = powerPlantsList.GetItems(query);
context.Load(items);
context.ExecuteQuery();
foreach (ListItem listItem in items)
{
SPpowerPlant powerPlant = new SPpowerPlant();
powerPlant.projectName = listItem["Project"].ToString();
powerPlant.location = listItem["Loacation"].ToString();
powerPlant.country = listItem["Country"].ToString();
powerPlant.currency = listItem["Currency"].ToString();
powerPlant.shortName = listItem["Short Name"].ToString();
powerPlant.spaceUrl = listItem["Space"].ToString();
powerPlant.numberOfWtgs = Convert.ToInt32(listItem["Number of WTGs"]);
powerPlant.mwWtg = Convert.ToDouble(listItem["MW WTG"]);
powerPlant.mwTotal = Convert.ToDouble(listItem["MW Total"]);
powerPlant.projectShareWeb = Convert.ToDouble(listItem["Project Share "]);
powerPlant.mwWeb = Convert.ToDouble(listItem["MW "]);
powerPlant.phaseDescription = listItem["Phase Description"].ToString();
powerPlant.projectProgress = Convert.ToDouble(listItem["Project Progress"]);
powerPlant.mwDeveloped = Convert.ToDouble(listItem["MW developed"]);
powerPlant.possibleWtgTypes = listItem["Possible WTG Types"].ToString();
powerPlant.hubHeight = listItem["Hub Height"].ToString();
powerPlant.allPermits = Convert.ToDateTime(listItem["All Permits"]);
powerPlant.cod = Convert.ToDateTime(listItem["COD"]);
powerPlant.projectManager = listItem["Project manager"].ToString();
powerPlant.technology = listItem["Technology"].ToString();
powerPlant.state = listItem["State"].ToString();
powerPlant.stateSince = Convert.ToDateTime(listItem["State since"]);
powerPlant.visibility = listItem["Visibillity"].ToString();
powerPlant.phase = listItem["Phase"].ToString();
powerPlant.phaseNumber = listItem["Phase Number"].ToString();
//Console.WriteLine(listItem["Currency"]);
powerPlantList.Add(powerPlant);
}
return powerPlantList;
}
I tied it with an lambda expression but no success.
Well the problem was that my listitem["names"] where not correct.
To get that stuff to work you need to go to the sharepoint site and look at the link when you sort it there you see the right name for the listitem.
New and working form:
//Loads only a Projeclist from sharepoint
public SPpowerPlantList loadProjectFromSharePoint()
{
SPpowerPlantList powerPlantList = new SPpowerPlantList();
ClientContext context = new ClientContext(powerPlantSite);
List powerPlantsList = context.Web.Lists.GetByTitle("Power Plants");
CamlQuery query = CamlQuery.CreateAllItemsQuery(100);
//query.ViewXml = #"<View><Query> </Query></View>";
ListItemCollection items = powerPlantsList.GetItems(query);
//context.Load(web.Lists,
// lists => lists.Include(list => list.Title, // For each list, retrieve Title and Id.
// list => list.Id,
// list => list.Description));
context.Load(items);
context.ExecuteQuery();
foreach (ListItem listItem in items)
{
SPpowerPlant powerPlant = new SPpowerPlant();
powerPlant.projectName = listItem["Title"].ToString();
powerPlant.location = listItem["Location"].ToString();
powerPlant.country = listItem["Country"].ToString();
powerPlant.currency = listItem["Currency"].ToString();
powerPlant.shortName = listItem["Short_x0020_Name"].ToString();
powerPlant.spaceUrl = listItem["Space"].ToString();
powerPlant.numberOfWtgs = Convert.ToInt32(listItem["Number_x0020_of_x0020_WTGs"]);
//Console.WriteLine(listItem[""]);
//powerPlantList.Add(powerPlant);
}
return null;

I am trying to transfer files from one document library on one farm to another. Since both are accessible from same network, I thought of getting column values from source and directly add it into a item on destination. Also upload the file along with the item.
List list = ccSource.Web.Lists.GetByTitle("Source Library");
ccSource.ExecuteQuery(); // ccSource is initialized with source Site collection
CamlQuery query = new CamlQuery();
ListItemCollection itemCollection = list.GetItems(CamlQuery.CreateAllItemsQuery()); //Query can also be selective
ccSource.Load(list);
ccSource.Load(itemCollection);
ccSource.ExecuteQuery();
ccSource.Load(ccSource.Web);
string[] coloumnsList = System.IO.File.ReadAllLines(#"E:\Coloumns.txt");
foreach (ListItem item in itemCollection)
{
ClientContext ccTarget. = new ClientContext("http://TargetSC/sites/mysite");
ccTarget.Credentials = new NetworkCredential("username", "pass", "domain");
ccTarget.ExecuteQuery();
var targetList = ccTarget.Web.Lists.GetByTitle("TargetLibrary");
string diskFilePath = #"E:\downloadedFile.docx"; //I have skipped the download code
var fileInfo1 = new FileCreationInformation
{
Url = System.IO.Path.GetFileName(diskFilePath),
Content = System.IO.File.ReadAllBytes(diskFilePath),
Overwrite = true
};
var file = targetList.RootFolder.Files.Add(fileInfo1);
var itemTar = file.ListItemAllFields;
//update list values
foreach (var allFields in item.FieldValues)
{
if (allFields.Key == "FileLeafRef" || checkColoumn(coloumnsList,allFields.Key))
itemTar[allFields.Key] = allFields.Value;
}
itemTar.Update();
ccTarget.ExecuteQuery(); //Exception here
}
public static bool checkColoumn(string[] arr,string query)
{
bool flag = false;
for (int i = 0; i < arr.Length; i++)
{
if (arr[i].Equals(query))
{flag = true; break;}
}
return flag;
}
I am getting exception:
The given guid does not exist in the term storeon
ccTarget.exceuteQuery()
I am trying to read the value of a particular field in a SharePoint Custom List.
The Custom List has the following fields: Field1, Field2 and Field3
When I call the code below:
public static string GetLastTargetColumnValue(string sharePointSiteUrl, string sharePointListName, string targetColumnName)
{
string targetColumnValue = string.Empty;
using (var clientContext = new ClientContext(sharePointSiteUrl))
{
clientContext.Credentials = new NetworkCredential("userName", "password");
var list = clientContext.Web.Lists.GetByTitle(sharePointListName);
var query = CamlQuery.CreateAllItemsQuery(100);
var items = list.GetItems(query);
clientContext.Load(items);
clientContext.ExecuteQuery();
var listItem = items.Last();
foreach (var fieldValue in listItem.FieldValues)
{
Console.WriteLine(fieldValue.Key + ":" + fieldValue.Value + Environment.NewLine);
}
}
targetColumnValue = listItem[targetColumnName] as string;
return targetColumnValue;
}
The error message is:
Additional information: The property or field has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.
The fields which are displayed in the foreach show "Field1" and "Field2". Do I have to explicitly request "Field3". If yes how?
I had to get the internal name before querying the value for some reason. Here is the code that worked:
public static string GetLastTargetColumnValue(string sharePointSiteUrl, string sharePointListName, string targetColumnName)
{
string targetColumnValue = string.Empty;
using (var clientContext = new ClientContext(sharePointSiteUrl))
{
clientContext.Credentials = new NetworkCredential("userName", "password");
var list = clientContext.Web.Lists.GetByTitle(sharePointListName);
var field = list.Fields.GetByInternalNameOrTitle(targetColumnName);
var textField = clientContext.CastTo<FieldText>(field);
var query = CamlQuery.CreateAllItemsQuery(100);
var items = list.GetItems(query);
clientContext.Load(textField);
clientContext.Load(items);
clientContext.ExecuteQuery();
var listItem = items.Last();
targetColumnValue = listItem[textField.InternalName] as string;
}
return targetColumnValue;
}
