how i can decode them

HttpUtility.UrlDecode() is the way to go. You find the documentation here: http://msdn.microsoft.com/en-us/library/system.web.httputility.urldecode.aspx

You could use the Server.UrlDecode() method.

From the docs:

String DecodedString = Server.UrlDecode(EncodedString);

Server.URLDecode( ). I'm assuming you're talking about ASP.net here - you didn't say.

ASP.Net right?

string Url = Server.UrlDecode("http%3A%2F%2Fgoogle.com");

You can use the following method to decode URLs:

System.Web.HttpUtility.UrlDecode
