HttpListenerRequest.ContentLength64 Property

Note: This property is new in the .NET Framework version 2.0.

Gets the length of the body data included in the request.

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

public long ContentLength64 { get; }
/** @property */
public long get_ContentLength64 ()

public function get ContentLength64 () : long

Property Value

The value from the request's Content-Length header. This value is -1 if the content length is not known.

The Content-Length header expresses the length, in bytes, of the body data that accompanies the request.

For a complete list of request headers, see the HttpRequestHeader enumeration.

The following code example uses the ContentLength64 property while processing body data.

public static void ShowRequestData (HttpListenerRequest request)
    if (!request.HasEntityBody)
        Console.WriteLine("No client data was sent with the request.");
    System.IO.Stream body = request.InputStream;
    System.Text.Encoding encoding = request.ContentEncoding;
    System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
    if (request.ContentType != null)
        Console.WriteLine("Client data content type {0}", request.ContentType);
    Console.WriteLine("Client data content length {0}", request.ContentLength64);
    Console.WriteLine("Start of client data:");
    // Convert the data to a string and display it on the console.
    string s = reader.ReadToEnd();
    Console.WriteLine("End of client data:");
    // If you are finished with the request, it should be closed also.
