HttpListenerResponse.ContentEncoding Property

Gets or sets the Encoding for this response's OutputStream.

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

'Declaration
Public Property ContentEncoding As Encoding

Property Value

Type: System.Text.Encoding
An Encoding object suitable for use with the data in the OutputStream property, or Nothing if no encoding is specified.

An Encoding object can be used to convert byte sequences into character sets (code pages) and characters into byte sequences.

The following code example demonstrates using this property.


Private Shared message403 As String
Private Shared Sub SendBadCertificateResponse(ByVal response As HttpListenerResponse)
    Dim message As New StringBuilder()
    message.Append("<HTML><BODY>")
    message.Append("<p> Error message 403: Access is denied due to a missing or invalid client certificate.</p>")
    message.Append("</BODY></HTML>")
    message403 = message.ToString()

    ' Set up an authentication error response template.
    response.StatusCode = CInt(HttpStatusCode.Forbidden)
    response.StatusDescription = "403 Forbidden"
    response.ProtocolVersion = New Version("1.1")
    response.SendChunked = False

    ' Turn the error message into a byte array using the 
    ' encoding from the response when present.
    Dim encoding As System.Text.Encoding = response.ContentEncoding
    If encoding Is Nothing Then
        encoding = System.Text.Encoding.UTF8
        response.ContentEncoding = encoding
    End If

    Dim buffer() As Byte = encoding.GetBytes(message403)
    response.ContentLength64 = buffer.Length
    ' Write the error message.
    Dim stream As System.IO.Stream = response.OutputStream
    stream.Write(buffer, 0, buffer.Length)
    ' Send the response.
    response.Close()
End Sub
