HttpListenerRequest.ContentLength64 Property

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

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

Public ReadOnly Property ContentLength64 As Long

Property Value

Type: System.Int64
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 Shared Sub ShowRequestData(ByVal request As HttpListenerRequest)
    If Not request.HasEntityBody Then
        Console.WriteLine("No client data was sent with the request.")
    End If
    Dim body As System.IO.Stream = request.InputStream
    Dim encoding As System.Text.Encoding = request.ContentEncoding
    Dim reader As New System.IO.StreamReader(body, encoding)
    If request.ContentType IsNot Nothing Then
        Console.WriteLine("Client data content type {0}", request.ContentType)
    End If
    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.
    Dim s As String = reader.ReadToEnd()
    Console.WriteLine("End of client data:")
    ' If you are finished with the request, it should be closed also.
End Sub
