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

'Declaration

Return Value

Type: System.IO.Stream
A Stream for writing data to the file system resource.

ExceptionCondition
WebException

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:")
                    Dim userInput As String = Console.ReadLine()

                    ' Convert the string to a byte array. 
                    Dim encoder As New ASCIIEncoding
                    Dim byteArray As Byte() = encoder.GetBytes(userInput)

                    ' Set the ContentLength property.
                    myFileWebRequest.ContentLength = byteArray.Length

                    Dim contentLength As String = myFileWebRequest.ContentLength.ToString()

                    Console.WriteLine(ControlChars.Lf + "The content length is {0}.", contentLength)


                    ' Get the file stream handler to write to the file. 
                    Dim readStream As Stream = myFileWebRequest.GetRequestStream()

                    ' Write to the 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(ControlChars.Lf + "The String you entered was successfully written to the file.")
