例

次のコード例では、 メソッドを GetRequestStream 使用して、ファイルへの書き込みに使用されるストリーム インスタンスを取得します。 クラスの完全な例を FileWebRequest 参照してください。

// 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.");

' 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.")

注釈
