Examples
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.
}
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)
Console.WriteLine("End of client data:")
body.Close()
reader.Close()
' If you are finished with the request, it should be closed also.
End Sub
Remarks
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 https://www.rfc-editor.org.
The ContentType is null when there is no Content-Type
header in the request.
