Question

I need to pass an array from JavaScript to a page method in C#. I have tried using a parameter in the C# method of IList and also a string[] array. Both ways throw an exception ‘cannot convert an object of type system.string to xxx’, where xxx is the parameter type in the C# method. I am passing the object from jQuery as a json object, and looks like it is coming through properly. Here is what it looks like:

{'testNumbers':'5555555555,3333333333,4444444444'} 

What am I doing wrong here?

EDIT: C# Code:

[WebMethod()] public static void ProcessAction(string[] testNumbers) {     var dataProvider = new DataProvider();     dataProvider.ProcessAction(testNumbers); }

Hmm, two things:

1. JSON arrays have square brackets around them
2. JSON numbers aren’t quoted.

Try this instead:

{'testNumbers': [5555555555,3333333333,4444444444]}
