FileWebResponse.GetResponseStream Method

Returns the data stream from the file system resource.

Namespace: System.Net
Assembly: System (in system.dll)

public:
virtual Stream^ GetResponseStream () override
public Stream GetResponseStream ()
public override function GetResponseStream () : Stream
Not applicable.

Return Value

A Stream for reading data from the file system resource.

The GetResponseStream method returns the data stream from the file system resource.

NoteNote:

The response stream must be closed to avoid running out of system resources. The response stream can be closed by calling Stream.Close or Close

The following example uses the GetResponseStream method to return the data stream from the file system resource.

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();
