Q:

Is it possible to programmatically execute JSON queries with C# (ASP.NET)

As the title says: is it possible?
You should think of the following scenario: I press a button in ASP.NET -> some C# backend -> Execute a JSON string
So something like this:
protected void Unnamed1_Click(object sender, EventArgs e)
{
       string check = (string)(Session["usr"])

       if(check == null;)
       {
          // Execute JSON
       }
       else
       {
          Response.Redirect("~/Home.aspx");
       }
}

Does anyone know how to do this? 
Thanks in advance.

A:

You need to use this method
RegisterStartupScript(scriptname, jsonstring);

This will put the script on top of the html page.
