تجزیه یک آدرس اینترنتی (Uri parsing)
با استفاده از اين ابع شما مي توانيد يك آدرس اينترنتي را تجزيه كنيد
چند نكته :
1- اين كد فقط در .net 3 جواب خواهد داد
2- فضاي نام system.net.uri بايد اضافه شود
public static void ParseUri(Uri uri)
{
try
{
// System.Net.Uri class constructor has parsed it for us.
// new Uri("http://user:password@localhost:8080/www.abc.com/
// home%20page.htm?item=1233#stuff")
