AcceptTypes Property

HttpListenerRequest.AcceptTypes Property

Gets the MIME types accepted by the client.

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

'Declaration
Public ReadOnly Property AcceptTypes As String()

Property Value

Type: System.String()
A String array that contains the type names specified in the request's Accept header or Nothing if the client request did not include an Accept header.

The Accept header is a string of space-separated Multipurpose Internet Mail Extensions (MIME) type names (for example, image/jpeg), which indicate the MIME types that the client is prepared to accept and process in a response. The */* entry indicates that the client accepts any MIME type. For a detailed description of the Accept header, see RFC 2616, available at http://www.rfc-editor.org.

For a complete list of request headers, see the HttpRequestHeader enumeration.

The following code example demonstrates using this property.


Public Shared Sub ShowRequestProperties1(ByVal request As HttpListenerRequest)
    ' Display the MIME types that can be used in the response.
    Dim types() As String = request.AcceptTypes
    If types IsNot Nothing Then
        Console.WriteLine("Acceptable MIME types:")
        For Each s As String In types
            Console.WriteLine(s)
        Next s
    End If
    ' Display the language preferences for the response.
    types = request.UserLanguages
    If types IsNot Nothing Then
        Console.WriteLine("Acceptable natural languages:")
        For Each l As String In types
            Console.WriteLine(l)
        Next l
    End If

    ' Display the URL used by the client.
    Console.WriteLine("URL: {0}", request.Url.OriginalString)
    Console.WriteLine("Raw URL: {0}", request.RawUrl)
    Console.WriteLine("Query: {0}", request.QueryString)

    ' Display the referring URI.
    Console.WriteLine("Referred by: {0}", request.UrlReferrer)

    'Display the HTTP method.
    Console.WriteLine("HTTP Method: {0}", request.HttpMethod)
    'Display the host information specified by the client;
    Console.WriteLine("Host name: {0}", request.UserHostName)
    Console.WriteLine("Host address: {0}", request.UserHostAddress)
    Console.WriteLine("User agent: {0}", request.UserAgent)
End Sub
