Question

how can display a string from a rest webservice in windows forms my xml looks like this:

<string>whatever</string>

How can you display that in a textbox in win forms?

If I try

        string uri = string.Format("etc/{0}/{1} Sad.Text, Happy.Text");
        XDocument xDoc = XDocument.Load(uri);
        string mystring = xDoc.Element("String").Value;
        textBox1.Text = mystring;

You get an object reference error?

Answer 1

XML elements are case-sensitive. Try,

string mystring = xDoc.Element("string").Value;

A better way to solve the problem is to not use XML to return a simple string. The media type text/plain is designed to do that. If you are using Microsoft’s ASP.NET Web API just return

return new HttpResponseMessage() { 
            Content = new StringContent("etc/{0}/{1} Sad.Text, Happy.Text")
           };

and on the client (using this http://nuget.org/Packages/system.net.http) do,

var httpClient = new HttpClient();
textBox1.Text = httpClient.GetAsync(uri).Result.Content.ReadAsString();
