GetRequestStream Method

FileWebRequest.GetRequestStream Method ()


Returns a Stream object for writing data to the file system resource.

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

public override Stream GetRequestStream()

Return Value

Type: System.IO.Stream

A Stream for writing data to the file system resource.

Exception Condition

The request times out.

The GetRequestStream method provides synchronous access to the Stream. For asynchronous access, use the BeginGetRequestStream and EndGetRequestStream methods.

The following code example uses the GetRequestStream method to obtain a stream instance used to write to the file. Refer to the complete example in the FileWebRequest class.

// 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.
Stream readStream = myFileWebRequest.GetRequestStream ();

// 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
// sharing of the folder containg 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 to the file.");
