HttpListenerRequest..::.AcceptTypes Property

Gets the MIME types accepted by the client.

Namespace: System.Net
Assembly: System (in System.dll)
Syntax
Public ReadOnly Property AcceptTypes As String()
public string[] AcceptTypes { get; }
public:
property array<String^>^ AcceptTypes {
	array<String^>^ get ();
}
member AcceptTypes : string[]

Property Value

Type: array<System..::.String>[]()[]
A String array that contains the type names specified in the request's Accept header or nullNothingnullptra null reference (Nothing in Visual Basic) if the client request did not include an Accept header.
Remarks

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.

Examples

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


public static void ShowRequestProperties1 (HttpListenerRequest request)
{
    // Display the MIME types that can be used in the response.
    string[] types = request.AcceptTypes;
    if (types != null)
    {
        Console.WriteLine("Acceptable MIME types:");
        foreach (string s in types)
        {
            Console.WriteLine(s);
        }
    }
    // Display the language preferences for the response.
    types = request.UserLanguages;
    if (types != null)
    {
        Console.WriteLine("Acceptable natural languages:");
        foreach (string l in types)
        {
            Console.WriteLine(l);
        }
    }

    // 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);
}
