HttpListenerRequest.ContentType Property

Note: This property is new in the .NET Framework version 2.0.

Gets the MIME type of the body data included in the request.

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

'Declaration
Public ReadOnly Property ContentType As String
'Usage
Dim instance As HttpListenerRequest
Dim value As String

value = instance.ContentType

/** @property */
public String get_ContentType ()

public function get ContentType () : String

Property Value

A String that contains the text of the request's Content-Type header.

If a client includes body data in a request, it declares the Multipurpose Internet Mail Extensions (MIME) type of the body data in the Content-Type header. For example, the default MIME type of data returned from a Web form using the POST method is application/x-www-form-urlencoded.

For a complete list of request headers, see the HttpRequestHeader enumeration and RFC 2616, available at http://www.rfc-editor.org.

The following code example demonstrates how to use this 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.
}
