I use web method, so I can pass string from code behind to JavaScript function. but now in code behind I have 2D array and don't know how to pass it.

1- array in code behind is the same in JavaScript? 2- do I need to convert it and send or do I need to make a string and then send? 3- is it possible to send and read array directly without any changes?

what is best and quickest way?

Did you try: new JavaScriptSerializer().Serialize(your_array) ?? – Alex Denysenko Sep 24 '13 at 18:11
is it in code behind? i have a 2d array and need to send to javascript and there with array. – Mohammad Adibi Sep 24 '13 at 18:13
Yes, your method would: return new JavaScriptSerializer().Serialize(toReturn); assuming toReturn is your array – Alex Denysenko Sep 24 '13 at 18:14
it doesn't work i work vs2010 – Mohammad Adibi Sep 24 '13 at 18:21
Did you reference using System.Web.Script.Serialization ? Because VS has nothing to do with it - its .Net Web assembly. – Alex Denysenko Sep 24 '13 at 18:23
Imports System.Web.Script.Serialization//////Dim returnKey(,) As String = {{"", ""}}///////returnKey = {{"ant", "aunt"}, {"Sam", "Samantha"}, {"clozapine", "quetiapine"}}/////Return JavaScriptSerializer().Serialize(returnKey) – Mohammad Adibi Sep 24 '13 at 18:31
This is usually how would you serialize your stuff for json to transfer. Sorry I couldn't help you. – Alex Denysenko Sep 24 '13 at 18:38
