HttpListenerResponse.ContentEncoding Property

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

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

public Encoding ContentEncoding { get; set; }

Property Value

Type: System.Text.Encoding
An Encoding object suitable for use with the data in the OutputStream property, or null 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.

static string message403;
static HttpListenerResponse preMade403Response;
static void SendBadCertificateResponse(HttpListenerResponse response)
{
    if (preMade403Response == null)
    {
        // Set up an authentication error response template.
        response.StatusCode = (int)HttpStatusCode.Forbidden;
        response.StatusDescription = "403 Forbidden";
        response.ProtocolVersion = new Version("1.1");
        response.SendChunked = false;

        preMade403Response = response;
    }
    else
    {
        response.CopyFrom(preMade403Response);
    }

    // The response body cannot be saved in the template.

    StringBuilder message = 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();

    // Turn the error message into a byte array using the  
    // encoding from the response when present.
    System.Text.Encoding encoding = response.ContentEncoding;
    if (encoding == null)
    {
        encoding = System.Text.Encoding.UTF8;
        response.ContentEncoding = encoding;
    }

    byte[] buffer = encoding.GetBytes(message403);
    response.ContentLength64 = buffer.Length;
    // Write the error message.
    System.IO.Stream stream = response.OutputStream;
    stream.Write(buffer, 0, buffer.Length);
    // Send the response.
    response.Close();
}
