Public Function MakeRelative (toUri As Uri) As String

参数

toUri

Uri

与当前 URI 进行比较的 URI。

返回

String

如果此 URI 实例与 toUri 的主机名和方案相同，则此方法返回一个表示相对 URI 的 String。若将此相对 URI 追加到当前 URI 实例，就可以得到 toUri 参数。

如果主机名或方案不同，则此方法返回一个表示 String 参数的 toUri。

属性

ObsoleteAttribute

例外

ArgumentNullException

toUri 为 null。

InvalidOperationException

此实例代表一个相对 URI，而此方法仅对绝对 URI 有效。

示例

以下示例创建 2 Uri 个实例。 路径信息的差异将写入控制台。

// Create a base Uri.
Uri^ address1 = gcnew Uri( "http://www.contoso.com/" );

// Create a new Uri from a string.
Uri^ address2 = gcnew Uri( "http://www.contoso.com/index.htm?date=today" );

// Determine the relative Uri.  
Console::WriteLine( "The difference is {0}", address1->MakeRelativeUri( address2 ) );

// Create a base Uri.
Uri address1 = new Uri("http://www.contoso.com/");

// Create a new Uri from a string.
Uri address2 = new Uri("http://www.contoso.com/index.htm?date=today");

// Determine the relative Uri.
Console.WriteLine("The difference is {0}", address1.MakeRelativeUri(address2));

// Create a base Uri.
let address1 = Uri "http://www.contoso.com/"

// Create a new Uri from a string.
let address2 = Uri "http://www.contoso.com/index.htm?date=today"

// Determine the relative Uri.
printfn $"The difference is {address1.MakeRelativeUri address2}"

    ' Create a base Uri.
    Dim address1 As New Uri("http://www.contoso.com/")
    
    ' Create a new Uri from a string.
    Dim address2 As New Uri("http://www.contoso.com/index.htm?date=today")
    
    ' Determine the relative Uri.  
    Console.WriteLine("The difference is {0}", address1.MakeRelativeUri(address2))

End Sub

注解

下表显示了 URI 实例 toUri和调用 MakeRelative结果。

当前 URI 实例	toUri	返回值
http://www.contoso.com/	http://www.contoso.com/test/test.htm	test/test.htm
http://www.contoso.com/test1/	http://www.contoso.com/	../
http://www.contoso.com:8000/	http://www.contoso.com/test/test.htm	http://www.contoso.com/test/test.htm
http://username@www.contoso.com/	http://www.contoso.com/test1/test1.txt	test1/test1.txt

用户信息（如果存在于 URI 中）将被忽略。
