public:
 abstract property Uri ^ ResponseUri { Uri ^ get(); };
public:
 virtual property Uri ^ ResponseUri { Uri ^ get(); };
public abstract Uri ResponseUri { get; }
public virtual Uri ResponseUri { get; }
member this.ResponseUri : Uri
Public MustOverride ReadOnly Property ResponseUri As Uri
Public Overridable ReadOnly Property ResponseUri As Uri

属性值

Uri

Uri 类的实例,包含实际响应此请求的 Internet 资源的 URI。

例外

当未在子类中重写该属性时,试图获取或设置该属性。

示例

以下示例使用 ResponseUri 属性来确定 的来源位置 WebResponse

Uri^ ourUri = gcnew Uri( url );

// Create a 'WebRequest' object with the specified url.
WebRequest^ myWebRequest = WebRequest::Create( url );

// Send the 'WebRequest' and wait for response.
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Use "ResponseUri" property to get the actual Uri from where the response was attained.
if ( ourUri->Equals( myWebResponse->ResponseUri ) )
{
   Console::WriteLine( "\nRequest Url : {0} was not redirected", url );
}
else
{
   Console::WriteLine( "\nRequest Url : {0} was redirected to {1}", url, myWebResponse->ResponseUri );
}

// Release resources of response object.
myWebResponse->Close();
Uri ourUri = new Uri(url);            

// Create a 'WebRequest' object with the specified url. 
WebRequest myWebRequest = WebRequest.Create(url); 

// Send the 'WebRequest' and wait for response.
WebResponse myWebResponse = myWebRequest.GetResponse(); 

// Use "ResponseUri" property to get the actual Uri from where the response was attained.
if (ourUri.Equals(myWebResponse.ResponseUri))
    Console.WriteLine("\nRequest Url : {0} was not redirected",url);   
else
    Console.WriteLine("\nRequest Url : {0} was redirected to {1}",url,myWebResponse.ResponseUri);   
// Release resources of response object.
myWebResponse.Close();

Dim ourUri As New Uri(url)
' Create a 'WebRequest' object with the specified url. 

Dim myWebRequest As WebRequest = WebRequest.Create(url)

' Send the 'WebRequest' and wait for response.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

' "ResponseUri" property is used to get the actual Uri from where the response was attained.
If ourUri.Equals(myWebResponse.ResponseUri) Then
    Console.WriteLine(ControlChars.Cr + "Request Url : {0} was not redirected", url)
Else
    Console.WriteLine(ControlChars.Cr + "Request Url : {0} was redirected to {1}", url, myWebResponse.ResponseUri)
End If 

' Release resources of response object.
myWebResponse.Close()

注解

属性 ResponseUri 包含实际提供响应数据的 Internet 资源的 URI。 如果基础协议允许重定向请求,则此资源可能不是最初请求的 URI。

注意

WebResponse 是类 abstract 。 实例在运行时的实际行为 WebResponse 由 返回 WebRequest.GetResponse的后代类决定。 有关默认值和异常的详细信息,请参阅子代类的文档,例如 HttpWebResponseFileWebResponse
