HttpWebResponse.Close 方法

定义

命名空间:

System.Net

程序集:

System.Net.Requests.dll

Source:

HttpWebResponse.cs

关闭响应流。

public:
 override void Close();

public override void Close ();

override this.Close : unit -> unit

Public Overrides Sub Close ()

例外

ObjectDisposedException

仅限 .NET Core：已释放此 HttpWebResponse 对象。

示例

以下示例演示如何关闭 HttpWebResponse。

// Creates an HttpWebRequest for the specified URL.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( url ) );
// Sends the HttpWebRequest and waits for a response.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
Console::WriteLine( "\nResponse Received::Trying to Close the response stream.." );
// Releases the resources of the response.
myHttpWebResponse->Close();
Console::WriteLine( "\nResponse Stream successfully closed" );

// Creates an HttpWebRequest for the specified URL.
    HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
    // Sends the HttpWebRequest and waits for a response.
    HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
    Console.WriteLine("\nResponse Received.Trying to Close the response stream..");
    // Releases the resources of the response.
    myHttpWebResponse.Close();
    Console.WriteLine("\nResponse Stream successfully closed");

' Creates an HttpWebRequest for the specified URL. 
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)
' Sends the HttpWebRequest and waits for a response.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
Console.WriteLine("Response Received.Trying to Close the response stream..")
' Releases the resources of the response.
myHttpWebResponse.Close()
Console.WriteLine("Response Stream successfully closed")

注解

方法 Close 关闭响应流，并释放与资源的连接，以供其他请求重复使用。

调用 Close 方法后，不应访问 对象的任何属性HttpWebResponse。 在 .NET Core 上， ObjectDisposedException 会引发 。

必须调用 Stream.Close 或 HttpWebResponse.Close 方法来关闭流并释放连接以供重复使用。 不需要同时 Stream.Close 调用 和 HttpWebResponse.Close，但这样做不会导致错误。 未能关闭流可能会导致应用程序连接不足。
