Creating JSON output file in C#

How can I expose the data in json format ..??? I tried creating a JSON string using C# code in an aspx file and outputting it. For example, On opening default.aspx on browser , it out puts only json string. But I can't use the default.aspx link while processing in android sdk as the http response will include html tags also.

Basically if I select view source when I open the dafault.aspx, I can see html tags not just the JSON string. when I open json api for twitter,google calender and select view s开发者_开发问答ource they does not contain html. Can anyone help me create only json out put ...??? I have data in sql server and quite good at C# coding.

Thanks in advance ....!!!

something like:

using System.Web.Script.Serialization; 

public class Person
{
   public string firstName = "bp";
   public string lastName = "581";
}

public partial class MyPage : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e) 
   { 
      Person p = new Person();
      string output = JavaScriptObjectSerializer.Serialize(p);
      Response.Write(output);
      Response.Flush();
      Response.End();
   }          
 } 

This is the aspx code behind example. The aspx file gets ignored after Response.End(). Or do it in an ashx file and forgo htmlpage markup.

Or even better, consider using a web service. WCF or an asmx .

You should make an ASHX handler.

You are probably not clearing the content before writing out the JSON string. It is much easier to do this in a "generic handler", i.e. an ashx file. Implement the ProcessRequest method, set the content type to "application/json", and write out your data.

You can try to return C# object.

public JsonResult GetPerson()
{
   var p = new Person();
   p.FirstName = "Name";
   p.LastName = "LastName";
   return Json(p);
}

So you will get:

{
   "FirstName" : "Name",
   "LastName" : "LastName"
}
