member this.MakeRelative : Uri -> stringmember this.MakeRelative : Uri -> stringPublic Function MakeRelative (toUri As Uri) As String参数
- toUri
- Uri
与当前 URI 进行比较的 URI。
返回
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
例外
toUri 为 null。
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。
