Try using JavaScriptSerializer like following:

c# Code

Student student = new Student();
System.Web.Script.Serialization.JavaScriptSerializer oSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
string StudentJson = oSerializer.Serialize(resources);

and in your aspx code get it like:

<script type="text/javascript">
    var jsonStudent = <%=StudentJson%>;            
</script>

Please make sure that StudentJson is a public or protected property in your backend class

You need to put the list in javascript format. In pure javascript you are looking for the following output (as an example):

var jsList = ['val1', 'val2', 'val3'];

To get this from .NET you need to use the Join function to bine list items into the appropriate format. The plete line of code looks like:

var jsList = <%= "['" + string.Join("', '", myObjList.ToArray()) + "']" %>;

Note that this assumes your "ToString" on your elements generates the output you are looking for and does not include single quotes. Hope that helps!
