class GFG {
  
    // Main Method
    public static void Main()
    {
        // Create a new Uri from a string address.

Converted string is: http://www.contoso.com/thick and thin.htm

范例2：

// C# program to demonstrate the
// Uri.ToString() Method
using System;
using System.Globalization;

    public static void Main()
    {
  
        // calling get() method
        get(new Uri("http://www.contoso.com"));
        get(new Uri("http://www.google.com"));
    }
  
    // defining get() method
    public static void get(Uri uri)
    {
  
        // Converts a specified uri 
        // into its string equivalent.
