예제

다음 코드 예제에서는 메서드를 GetRequestStream 사용하여 파일에 쓰는 데 사용되는 스트림 인스턴스를 가져옵니다. 클래스의 전체 예제를 FileWebRequest 참조하세요.

// Enter the string to write into the file.
Console::WriteLine( "Enter the string you want to write:" );
String^ userInput = Console::ReadLine();

// Convert the string to Byte array.
ASCIIEncoding^ encoder = gcnew ASCIIEncoding;
array<Byte>^byteArray = encoder->GetBytes( userInput );

// Set the ContentLength property.
myFileWebRequest->ContentLength = byteArray->Length;
String^ contentLength = myFileWebRequest->ContentLength.ToString();
Console::WriteLine( "\nThe content length is {0}.", contentLength );

// Get the file stream handler to write into the file.
Stream^ readStream = myFileWebRequest->GetRequestStream();

// Write to the file stream.
// Note. In order for this to work the file must be accessible
// on the network. This can be accomplished by setting the property
// sharing of the folder containg the file. The permissions
// can be set so everyone can modify the file.
// FileWebRequest::Credentials property cannot be used for this purpose.
readStream->Write( byteArray, 0, userInput->Length );
Console::WriteLine( "\nThe String you entered was successfully written into the file." );

// Enter the string to write to the file.
Console.WriteLine ("Enter the string you want to write:");

string userInput = Console.ReadLine ();

// Convert the string to a byte array.
ASCIIEncoding encoder = new ASCIIEncoding ();
byte[] byteArray = encoder.GetBytes (userInput);

// Set the ContentLength property.
myFileWebRequest.ContentLength = byteArray.Length;

string contentLength = myFileWebRequest.ContentLength.ToString ();

Console.WriteLine ("\nThe content length is {0}.", contentLength);

// Get the file stream handler to write to the file.

// Write to the file stream.
// Note.  For this to work, the file must be accessible
// on the network. This can be accomplished by setting the property

Dim userInput As String = Console.ReadLine()

' Convert the string to a byte array.

설명

메서드는 GetRequestStream .에 Stream대한 동기 액세스를 제공합니다. 비동기 액세스의 경우 해당 및 EndGetRequestStream 메서드를 BeginGetRequestStream 사용합니다.
