Uri.GetLeftPart(UriPartial) 方法

public:
 System::String ^ GetLeftPart(UriPartial part);

public string GetLeftPart(UriPartial part);

member this.GetLeftPart : UriPartial -> string

Public Function GetLeftPart (part As UriPartial) As String

参数

返回

实例的 Uri 指定部分。

例外

示例

以下示例创建一个 Uri 实例，并将路径写入控制台。

// Create Uri
Uri uriAddress = new Uri("http://www.contoso.com/index.htm#search");
Console.WriteLine(uriAddress.Fragment);
Console.WriteLine("Uri {0} the default port ", uriAddress.IsDefaultPort ? "uses" : "does not use");

Console.WriteLine("The path of this Uri is {0}", uriAddress.GetLeftPart(UriPartial.Path));
Console.WriteLine("Hash code {0}", uriAddress.GetHashCode());
// The example displays output similar to the following:
//        #search
//        Uri uses the default port
//        The path of this Uri is http://www.contoso.com/index.htm
//        Hash code -988419291

// Create Uri
let uriAddress = Uri "http://www.contoso.com/index.htm#search"
printfn $"{uriAddress.Fragment}"
printfn $"""Uri {if uriAddress.IsDefaultPort then "uses" else "does not use"} the default port """

printfn $"The path of this Uri is {uriAddress.GetLeftPart UriPartial.Path}"
printfn $"Hash code {uriAddress.GetHashCode()}"
// The example displays output similar to the following:
//        #search
//        Uri uses the default port
//        The path of this Uri is http://www.contoso.com/index.htm
//        Hash code -988419291

' Create Uri
Dim uriAddress As New Uri("http://www.contoso.com/index.htm#search")
Console.WriteLine(uriAddress.Fragment)
Console.WriteLine("Uri {0} the default port ", If(uriAddress.IsDefaultPort, "uses", "does not use")) 

Console.WriteLine("The path of this Uri is {0}", uriAddress.GetLeftPart(UriPartial.Path))
Console.WriteLine("Hash code {0}", uriAddress.GetHashCode())
' The example displays output similar to the following:
'        #search
'        Uri uses the default port
'        The path of this Uri is http://www.contoso.com/index.htm
'        Hash code -988419291

注解

该方法 GetLeftPart 返回一个字符串，其中包含 URI 字符串的最左侧部分，以指定的 part部分结尾。

该方法GetLeftPart等效于使用相应的GetComponents标志进行调用UriComponents。 例如：

• GetLeftPart(UriPartial.Authority) 与 GetComponents(UriComponents.Scheme | UriComponents.UserInfo | UriComponents.Host | UriComponents.Port, UriFormat.UriEscaped) 等效

GetLeftPart 在以下情况下包括分隔符：

• Scheme 包括方案分隔符。
• Authority 不包括路径分隔符。
• Path 包括原始 URI 中到查询或片段分隔符的路径分隔符和任何分隔符。
• Query Path包括查询及其分隔符。

以下示例演示了 URI 以及使用 GetLeftPart、Scheme或AuthorityPath调用Query的结果。
