C＃| Uri.IsBaseOf(Uri)方法

Uri.IsBaseOf(Uri)方法用于确定当前Uri实例是否为指定Uri实例的基础。

Syntax: public bool IsBaseOf (Uri uri);
Here, it takes the specified Uri instance to test.

Return Value: This method returns true if the current Uri instance is a base of uri otherwise, false.

Exception: This method throws ArgumentNullException if uri is null.

下面的程序说明了Uri.IsBaseOf(Uri)方法的用法：

范例1：

// C# program to demonstrate the
// Uri.IsBaseOf(Uri) Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // Declaring and initializing address1
        Uri address1 = new Uri("http://www.contoso.com/index.htm#search");
  
        // Declaring and intializing address2
        Uri address2 = new Uri("http://www.contoso.com/index.htm");
  
        // using IsBaseOf() method
        bool value = address1.IsBaseOf(address2);
  
        // Displaying the result
        if (value)
            Console.WriteLine("address1 instance is a base"+
                              " of the specified address2");
        else
            Console.WriteLine("address1 instance is not a "+
                          "base of the specified address2");
    }
}

输出：

address1 instance is a base of the specified address2

范例2：

// C# program to demonstrate the
// Uri.IsBaseOf(Uri) Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // calling get() method
        get(new Uri("http://www.contoso.com"),
           new Uri("http://www.contoso.com"));
  
        get(new Uri("http://www.google.com"), 
         new Uri("http://www.facebook.com"));
    }
  
    // defining get() method
    public static void get(Uri address1,
                           Uri address2)
    {
  
        // using IsBaseOf() method
        bool value = address1.IsBaseOf(address2);
  
        // Displaying the result
        if (value)
            Console.WriteLine("address1 instance is a "+
                      "base of the specified address2");
        else
            Console.WriteLine("address1 instance is "+
              "not a base of the specified address2");
    }
}

输出：

address1 instance is a base of the specified address2
address1 instance is not a base of the specified address2
