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:
property long long ContentLength64 {
	long long 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.");
        return;
    }
    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(s);
    Console.WriteLine("End of client data:");
    body.Close();
    reader.Close();
    // If you are finished with the request, it should be closed also.
}
