HttpListenerRequest.InputStream Property

Gets a stream that contains the body data sent by the client.

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

'Declaration
Public ReadOnly Property InputStream As Stream

Property Value

Type: System.IO.Stream
A readable Stream object that contains the bytes sent by the client in the body of the request. This property returns Null if no data is sent with the request.

If the client transmits data (for example, using the HTTP POST method), the stream returned by this method contains that data.

NoteNote

Closing the request does not close the stream returned by this property. When you no longer need the stream, you should close it by calling the Close method.

Notes to Callers

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.

The following code example demonstrates using this property to read the data sent with a request.


Public Shared Sub ShowRequestData(ByVal request As HttpListenerRequest)
    If Not request.HasEntityBody Then
        Console.WriteLine("No client data was sent with the request.")
        Return
    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(s)
    Console.WriteLine("End of client data:")
    body.Close()
    reader.Close()
    ' If you are finished with the request, it should be closed also.
End Sub
