    copied!<p>I've been working on this for 3 hours and have given up. i am simply trying to send data to an asp.net web method, using jQuery. The data is basically a bunch of key/value pairs. so i've tried to create an array and adding the pairs to that array.</p> <p>My WebMethod(aspx.cs) looks like this (this may be wrong for what i'm building in javascript, i just dont know): </p> <pre><code> [WebMethod] public static string SaveRecord(List&lt;object&gt; items) ..... </code></pre> <p>Here is my sample javascript:</p> <blockquote> <p>var items = new Array;</p> <pre><code> var data1 = { compId: "1", formId: "531" }; var data2 = { compId: "2", formId: "77" }; var data3 = { compId: "3", formId: "99" }; var data4 = { status: "2", statusId: "8" }; var data5 = { name: "Value", value: "myValue" }; items[0] = data1; items[1] = data2; items[2] = data3; items[3] = data4; items[4] = data5; </code></pre> </blockquote> <pre><code>Here is my jQuery ajax call: var options = { error: function(msg) { alert(msg.d); }, type: "POST", url: "PackageList.aspx/SaveRecord", data: { 'items': items }, contentType: "application/json; charset=utf-8", dataType: "json", async: false, success: function(response) { var results = response.d; } }; jQuery.ajax(options); </code></pre> <p>i get the error -<code>Invalid JSON primitive: items.</code>-</p> <p>so...if i do this:</p> <blockquote> <p>var DTO = { 'items': items };</p> </blockquote> <p>and set the data parameter like this: </p> <blockquote> <p>data: JSON.stringify(DTO)</p> </blockquote> <p>then i get this error:</p> <pre><code>Cannot convert object of type \u0027System.String\u0027 to type \u0027System.Collections.Generic.List`1[System.Object]\u0027 </code></pre>
