Examples

The following code example demonstrates displaying the headers in a WebHeaderCollection.

    // Displays the header information that accompanied a request.
public static void DisplayWebHeaderCollection(HttpListenerResponse response)
{
    WebHeaderCollection headers = response.Headers;
    // Get each header and display each value.
    foreach (string key in headers.AllKeys)
    {
        string[] values = headers.GetValues(key);
        if(values.Length > 0)
        {
            Console.WriteLine("The values of the {0} header are: ", key);
            foreach (string value in values)
            {
                Console.WriteLine("   {0}", value);
            }
        }
        else
        {
            Console.WriteLine("There is no value associated with the header.");
        }
    }
}

' Displays the header information that accompanied a request.
Public Shared Sub DisplayWebHeaderCollection(ByVal response As HttpListenerResponse)
    Dim headers As WebHeaderCollection = response.Headers

    ' Get each header and display each value.
    For Each key As String In headers.AllKeys
        Dim values As String() = headers.GetValues(key)

        If values.Length > 0 Then
            Console.WriteLine("The values of the {0} header are: ", key)

            For Each value As String In values
                Console.WriteLine("   {0}", value)
            Next
        Else
            Console.WriteLine("There is no value associated with the header.")
        End If
    Next
End Sub

Remarks

Response headers contain metadata information such as the date and time of the response, the identity of the responding server, and the MIME type of the data contained in the response body.

For a complete list of response headers, see the HttpResponseHeader enumeration.
