    text
    copied!<p>I'm having a class like the following:</p> <pre><code>using System; using System.Collections.Generic; using System.Runtime.Serialization; [DataContract()] public class TestCol : List&lt;Test&gt; { } [DataContract()] public class MainTest { public TestCol Components { get; set; } } [DataContract()] public class Test { public Test() { } public String Name { get; set; } } </code></pre> <p>And a webservice with the following webmethod like this:</p> <pre><code>[WebMethod] public String Test(MainTest input) { String rtrn = String.Empty; foreach (Test test in input.Components) rtrn += test.Name; return rtrn; } </code></pre> <p>Which is called by AJAX with the following method:</p> <pre><code>var Test = {}; Test.Name = "Test"; var MainTest = {}; MainTest.Components = []; MainTest.Components.push(Test); $.ajax({ type: "POST", url: "WebService/WSTest.asmx/Test", contentType: "application/json; charset=utf-8", dataType: "json", data: JSON.stringify({ "input": MainTest }), success: function(data, textStatus) { console.log("success"); }, error: function(XMLHttpRequest, textStatus, errorThrown) { window.console &amp;&amp; console.log &amp;&amp; console.log(XMLHttpRequest.responseText + " || " + textStatus + " || " + errorThrown); } }); </code></pre> <p>When executing the AJAX call, it will return errors. I found out that the error is with the typed class <code>TestCol</code>, which has no properties. Now do I have found 2 solutions that require changes in the C# classes:</p> <ol> <li><p>Remove the <code>TestCol</code> class and change the <code>Components</code> property to <code>List&lt;Test&gt;</code> datatype:</p> <pre><code>[DataContract()] public class MainTest { public List&lt;Test&gt; Components { get; set; } } [DataContract()] public class Test { public Test() { } public String Name { get; set; } } </code></pre></li> <li><p>Or add an extra property to the <code>TestCol</code> class and change the webmethod:</p> <pre><code>[DataContract()] public class TestCol : List&lt;Test&gt; { public List&lt;Test&gt; Components { get; set; } } [DataContract()] public class MainTest { public TestCol Components { get; set; } } [DataContract()] public class Test { public Test() { } public String Name { get; set; } } </code></pre> <p>&amp;</p> <pre><code>[WebMethod] public String Test(MainTest input) { String rtrn = String.Empty; foreach (Test test in input.Components.Components) rtrn += test.Name; return rtrn; } </code></pre></li> </ol> <p>Both solutions require changes in the C# classes, which I prefer not to, as other code is depended on it. <strong>Does anyone know a solution for this problem?</strong></p> <p><em>Edit</em>: I've uploaded a test solution, containing above code: <a href="http://jeroenvanwarmerdam.nl/content/temp/JSONtoClassWebservice.zip" rel="nofollow">http://jeroenvanwarmerdam.nl/content/temp/JSONtoClassWebservice.zip</a></p>
