L’exemple de code suivant illustre l’utilisation de la propriété ContentEncoding.The following code example demonstrates using the ContentEncoding property.

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.
}
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 System.IO.StreamReader = 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)

    reader.Close()
    ' If you are finished with the request, it should be closed also.
End Sub

Remarques

Un objet Encoding peut être utilisé pour convertir des séquences d’octets en jeux de caractères (pages de codes) et des caractères en séquences d’octets.An Encoding object can be used to convert byte sequences into character sets (code pages) and characters into byte sequences. Cette propriété utilise la valeur charset de l’en-tête Content-Type pour déterminer l’encodage.This property uses the charset value from the Content-Type header to determine the encoding. Si ces informations ne sont pas disponibles, cette propriété retourne Encoding.Default.If that information is not available, this property returns Encoding.Default.
