Ein Stream zum Lesen von Daten aus der Dateisystemressource.

Beispiele

Im folgenden Beispiel wird die GetResponseStream -Methode verwendet, um den Datenstrom aus der Dateisystemressource zurückzugeben.

Uri^ fileUrl = gcnew Uri( String::Concat( "file://", url ) );
// Create a 'FileWebrequest' Object* with the specified Uri.
FileWebRequest^ myFileWebRequest = (FileWebRequest^)( WebRequest::Create( fileUrl ) );
// Send the 'FileWebRequest' Object* and wait for response.
FileWebResponse^ myFileWebResponse = (FileWebResponse^)( myFileWebRequest->GetResponse() );

// Get the stream Object* associated with the response Object*.
Stream^ receiveStream = myFileWebResponse->GetResponseStream();

Encoding^ encode = System::Text::Encoding::GetEncoding( "utf-8" );
// Pipe the stream to a higher level stream reader with the required encoding format.
StreamReader^ readStream = gcnew StreamReader( receiveStream,encode );
Console::WriteLine( "\r\nResponse stream received" );

array<Char>^ read = gcnew array<Char>(256);
// Read 256 characters at a time.
int count = readStream->Read( read, 0, 256 );
Console::WriteLine( "File Data...\r\n" );
while ( count > 0 )
{
   // Dump the 256 characters on a String* and display the String* onto the console.
   String^ str = gcnew String( read,0,count );
   Console::Write( str );
   count = readStream->Read( read, 0, 256 );
}
Console::WriteLine( "" );
// Release resources of stream Object*.
readStream->Close();
// Release resources of response Object*.
myFileWebResponse->Close();

Uri fileUrl = new Uri("file://"+url);
// Create a 'FileWebrequest' object with the specified Uri.
FileWebRequest myFileWebRequest = (FileWebRequest)WebRequest.Create(fileUrl);
// Send the 'FileWebRequest' object and wait for response.
FileWebResponse myFileWebResponse = (FileWebResponse)myFileWebRequest.GetResponse();

// Get the stream object associated with the response object.
Stream receiveStream = myFileWebResponse.GetResponseStream();

Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
// Pipe the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader( receiveStream, encode );
Console.WriteLine("\r\nResponse stream received");

Char[] read = new Char[256];
// Read 256 characters at a time.
int count = readStream.Read( read, 0, 256 );
Console.WriteLine("File Data...\r\n");
while (count > 0)
{
    // Dump the 256 characters on a string and display the string onto the console.
    String str = new String(read, 0, count);
    Console.Write(str);
    count = readStream.Read(read, 0, 256);
}
Console.WriteLine("");
// Release resources of stream object.
readStream.Close();
// Release resources of response object.
myFileWebResponse.Close();

' CALLING METHOD GetResponseStream will return the stream associated with the response object.
Dim ReceiveStream As Stream = myFileWebResponse.GetResponseStream()

Dim encode As Encoding = System.Text.Encoding.GetEncoding("utf-8")
