Develop Reference

I used SvcUtil to create classes from WSDL. What do I deserialize into?

I used svcUtil.exe to create classes from https://gw.sam.gov/SAMWS/1.0/Entity?wsdl
but I cannot for the life of me find what to deserialize the result into? When I created my own classes the root is envelope but it isn't even in the new classes.
I can paste the classes but it is really long? Is there a general answer to this?
I will paste the classes upon request.
Thanks in advance...
The classes are over 10x too long to post.
Adding code for the pull:
static void Main(string[] args)
{
ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var _url = "https://gw.sam.gov/SAMWS/1.0/Entity";
//Run date is a specific date if provided otherwise use yesterday
DateTime startDateTime = DateTime.Now.AddDays(-1).Date;
for (int hr = 0; hr < 24; hr++)
{
XMLclassRequest xmlSoap = new XMLclassRequest();
string soap = xmlSoap.BuildSOAPrequest(startDateTime.AddHours(hr));
//string soap2 = xmlSoap.BuildSOAPrequest2(startDateTime.AddHours(hr));
string response = null; //This is the original pull with FAR and DFAR Responses
//string response2 = null; //This is FAR and DFAR
using (MyWebClient client = new MyWebClient())
{
client.Headers.Add("Content-Type", "text/xml;charset=utf-8");
client.Headers.Add("SOAPAction", "\"http://tempuri.org/IMyService/MyOperation\"");
try
{
response = client.UploadString(_url, soap);
//response2 = client.UploadString(_url, soap2);
}
catch
{ } //This will skip the hour attempted and move to next. The error I have been receiving is no data which is differently formatted XML that causes the error
}
//File.WriteAllText(#"D:\temp\bigpull.xml", response);
MemoryStream stream = null;
if (response != null)
{
byte[] byteArray = Encoding.Unicode.GetBytes(response);
stream = new MemoryStream(byteArray);
}
getEntities results;
XmlSerializer serializer = new XmlSerializer(typeof(getEntities));
try
{ results = (getEntities)serializer.Deserialize(stream); }
catch
{ } //This will skip the hour attempted and move to next. The error I have been receiving is no data which is differently formatted XML that causes the error
stream.Close();
string str;
}
The response is coming back. I just can't get it into an object to use.

I couldn't get this loaded into an object but ended up loading it to an XDocument and parsed that:
var _url = "https://gw.sam.gov/SAMWS/1.0/Entity";
//Run date is a specific date if provided otherwise use yesterday
DateTime startDateTime = DateTime.Now.AddDays(-1).Date;
for (int hr = 0; hr < 24; hr++)
{
XMLclassRequest xmlSoap = new XMLclassRequest();
string soap = xmlSoap.BuildSOAPrequest(startDateTime.AddHours(hr));
//string soap2 = xmlSoap.BuildSOAPrequest2(startDateTime.AddHours(hr));
string response = null; //This is the original pull with FAR and DFAR Responses
//string response2 = null; //This is FAR and DFAR
using (MyWebClient client = new MyWebClient())
{
client.Headers.Add("Content-Type", "text/xml;charset=utf-8");
client.Headers.Add("SOAPAction", "\"http://tempuri.org/IMyService/MyOperation\"");
try
{
response = client.UploadString(_url, soap);
//response2 = client.UploadString(_url, soap2);
}
catch
{ } //This will skip the hour attempted and move to next. The error I have been receiving is no data which is differently formatted XML that causes the error
}
//File.WriteAllText(#"D:\temp\far20190604.xml", response);
XDocument xdoc = XDocument.Parse(response);
var entities = from e in xdoc.Descendants("entity") select e;
foreach (var e in entities)
{
string DUNS = e.Descendants("DUNS").FirstOrDefault().Value;
var provisions = from p in e.Descendants("provision") select p;
foreach (var p in provisions)
{
string ParentID = p.Descendants("id").FirstOrDefault().Value;
var answers = from a in p.Descendants("answer") select a;
foreach (var a in answers)
{
var section = a.Descendants("section").Count()>0? a.Descendants("section").FirstOrDefault().Value : "";
var answerText = a.Descendants("answerText").Count() > 0 ? a.Descendants("answerText").FirstOrDefault().Value : "";
Console.WriteLine(DUNS + " " + ParentID + " " + section + " " + answerText);
}
}
}

Json child access yahoo weather json in C#

So I'm trying to get the weather from the Yahoo's weather Json, but the thing is I keep getting this error
{"Cannot access child value on Newtonsoft.Json.Linq.JValue."}
Right now I have no idea why is this happening. I checked the parenting a few times already, the spelling and all that.
public String GetWeather() {
StringBuilder theWebAddress = new StringBuilder();
theWebAddress.Append("https://query.yahooapis.com/v1/public/yql?");
theWebAddress.Append("q=" + System.Web.HttpUtility.UrlEncode("select * from weather.forecast where woeid in (select woeid from geo.places(1) where text='"+ city + ", "+ state + "') and u='" + units +"'"));
theWebAddress.Append("&format=json");
theWebAddress.Append("&diagnostics=false");
string results = "";
using (WebClient wClient = new WebClient())
{
results = wClient.DownloadString(theWebAddress.ToString());
}
JObject dataObject = JObject.Parse(results);
JArray jsonArray = (JArray)dataObject["query"]["results"]["channel"]; //This is the line that is generating the error.
foreach (var woeid in jsonArray)
{
//stocheaza informatiile in variabile
condition = woeid["item"]["condition"]["text"].ToString();
//System.Diagnostics.Debug.WriteLine(condition);
return condition;
}
return null;
}
The link to the API is here. So as far as I see, there is problem with getting the child of query or results. Any ideas? Thanks in advance.

I solved it by changing the code. Instead of using that code, I changed it with this
public string GetWeather(string info)
{
string results = "";
using (WebClient wc = new WebClient())
{
results = wc.DownloadString("https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%27galati%2C%20ro%27)%20and%20u%3D%22c%22&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys");
}
dynamic jo = JObject.Parse(results);
if (info == "cond")
{
var items = jo.query.results.channel.item.condition;
condition = items.text;
return condition;
}
}
Now it works as intended.

How to get redirect from HttpWebResponse?

I am trying to get a redirect from Google Maps using a project that is currently only at .Net Framework 4.0.
Take Microsoft's mailing address as an example:
1 Microsoft Way, Redmond, WA
Format a string that replaces Spaces , Commas , with Plus + signs:
https://www.google.com/maps?daddr=1+microsoft+way+redmond+wa
By the time Google finishes processing the page, the final URL has the Latitude and Longitude:
https://www.google.com/maps/dir//1+Microsoft+Way,+Redmond,+WA+98052/#47.6393095,-122.1327333,16z/data=!3m1!4b1!4m8!4m7!1m0!1m5!1m1!1s0x54906d73f7de150b:0x922499d19305e9a0!2m2!1d-122.1283559!2d47.6393096
I need the Latitude and Longitude from this URL.
I found this article already on SO:
Get a collection of redirected URLs from HttpWebResponse
Using the solution there, I created this very similar looking method:
private String latitude, longitude;
private void GetLatLongFromAddress(String p_street_name, String p_city, String p_state, String p_postal_code)
{
var street_name = String.Format("{0}", p_street_name.Replace(' ', '+')).Trim();
var city = String.Format("{0}", p_city).Trim();
var state = String.Format("{0}", p_state).Trim();
var postal_code = String.Format("{0}", p_postal_code).Trim();
var mapUrl = String.Format("http://maps.google.com/?daddr={0}+{1}+{2}+{3}",
street_name, city, state, postal_code);
var location = String.Copy(mapUrl);
while (!String.IsNullOrEmpty(location))
{
var req1 = (HttpWebRequest)HttpWebRequest.Create(location);
req1.AllowAutoRedirect = false;
// give page time to redirect?
// System.Threading.Thread.Sleep(5000);
using (var resp = (HttpWebResponse)req1.GetResponse())
{
location = resp.GetResponseHeader("Location");
if (!String.IsNullOrEmpty(location))
{
var postalIndex = location.IndexOf(postal_code);
var slashAtIndex = location.IndexOf("/#") + 1;
if ((postalIndex < slashAtIndex) && (slashAtIndex < location.Length))
{
var split = location.Substring(slashAtIndex).Split(',');
latitude = split[0];
longitude = split[1];
}
}
}
}
}
You can see where I format the original URL with this line:
var mapUrl = String.Format("http://maps.google.com/?daddr={0}+{1}+{2}+{3}",
street_name, city, state, postal_code);
The problem is with this line:
location = resp.GetResponseHeader("Location");
Every time I get the response, the returned location value is the same as the mapUrl value that I started with because Google does not redirect it immediately.
I tried adding a Sleep(5000) call, but that did not change anything.
How would I go about getting the final redirect?

Universal Windows App, cant execute doc.LoadXml(string)

I'm trying to retrieve WOIED through an universal windows app using the following code block-
string woeID;
private string GetWOEID(string zipCode)
{
woeID = "";
XmlDocument woeidData = new XmlDocument();
string query = String.Format("http://where.yahooapis.com/v1/places.q('{0}')?appid={1}", zipCode, YahooAPI_ID);
try
{
woeidData.LoadXml(query);
}
catch (Exception)
{
}
XmlNodeList kk = woeidData.GetElementsByTagName("woeid");
if (kk.Count != 0)
{
woeID = kk[0].InnerText;
textBox.Text = "";
GetWeather(); // Calling getweather method.
return woeID;
}
else
{
woeID = "";
textBox.Text = "";
return woeID;
}
}
where zipCode comes from an textBox input and YahooAPI_ID is my developer key. I need to retrieve the WOEID first to pass it on to GetWeather() method to get the weather report in xml from yahoo. But the problem is after try{woeidData.LoadXml(query);} it always steps into catch (exception){} in debugger. While this code block worked on winform apps before using the code try {woeidData.Load(query)}
Any pointers at what I'm doing wrong will be appreciated!

The XmlDocument.LoadXml method is expecting an actually string of xml, https://msdn.microsoft.com/en-us/library/system.xml.xmldocument.load(v=vs.110).aspx, not a uri pointing to a resource, you will need to get the contents of the http call seperately.
You could for example use the XmlDocument.Load method, which takes a stream and use a HttpWebRequest https://msdn.microsoft.com/en-us/library/system.net.httpwebrequest(v=vs.110).aspx and its GetResponse().GetResponseStream() methods to load the xml.

Ok so this is how I did it just in case someone wonders around and stumbled upon this...
private async void button_Click(object sender, RoutedEventArgs e)
{
string url = String.Format("http://url");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)await request.GetResponseAsync();
StreamReader reader = new StreamReader(response.GetResponseStream());
XmlDocument elementdData = new XmlDocument();
woeidData.Load(reader);
XmlNodeList element = woeidData.GetElementsByTagName("elementID");
}
