예제

다음 코드 예제에서는 속성을 설정합니다 ProtocolVersion .

// Create a new 'HttpWebRequest' Object to the mentioned URL.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( "http://www.microsoft.com" ) );
// Use the existing 'ProtocolVersion' , and display it onto the console.
Console::WriteLine( "\nThe 'ProtocolVersion' of the protocol used is {0}", myHttpWebRequest->ProtocolVersion );
// Set the 'ProtocolVersion' property of the 'HttpWebRequest' to 'Version1::0' .
myHttpWebRequest->ProtocolVersion = HttpVersion::Version10;
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
Console::WriteLine( "\nThe 'ProtocolVersion' of the protocol changed to {0}", myHttpWebRequest->ProtocolVersion );
Console::WriteLine( "\nThe protocol version of the response Object* is {0}", myHttpWebResponse->ProtocolVersion );

// Create a new 'HttpWebRequest' Object to the mentioned URL.
HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create("http://www.microsoft.com");
// Use the existing 'ProtocolVersion' , and display it onto the console.	
Console.WriteLine("\nThe 'ProtocolVersion' of the protocol used is {0}",myHttpWebRequest.ProtocolVersion);
// Set the 'ProtocolVersion' property of the 'HttpWebRequest' to 'Version1.0' .
myHttpWebRequest.ProtocolVersion=HttpVersion.Version10;
 // Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
 HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
Console.WriteLine("\nThe 'ProtocolVersion' of the protocol changed to {0}",myHttpWebRequest.ProtocolVersion);
Console.WriteLine("\nThe protocol version of the response object is {0}",myHttpWebResponse.ProtocolVersion);

' Create a new 'HttpWebRequest' Object to the mentioned URL.
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create("http://www.microsoft.com"), HttpWebRequest)
' Use the existing 'ProtocolVersion' , and display it onto the console.	
Console.WriteLine(ControlChars.Cr + "The 'ProtocolVersion' of the protocol used is {0}", myHttpWebRequest.ProtocolVersion)
' Set the 'ProtocolVersion' property of the 'HttpWebRequest' to 'Version1.0' .
myHttpWebRequest.ProtocolVersion = HttpVersion.Version10
'  Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
Console.WriteLine(ControlChars.Cr + "The 'ProtocolVersion' of the protocol changed to {0}", myHttpWebRequest.ProtocolVersion)
Console.WriteLine(ControlChars.Cr + "The protocol version of the response object is {0}", myHttpWebResponse.ProtocolVersion)

설명

클래스는 HttpWebRequest HTTP 버전 1.0 및 1.1만 지원합니다. 를 다른 버전으로 설정 ProtocolVersion 해도 예외가 발생합니다.

참고

현재 요청의 HTTP 버전을 설정하려면 클래스의 Version10HttpVersion 및 Version11 필드를 사용합니다.
