HttpListenerRequest::UserAgent Property
.NET Framework (current version)
Gets the user agent presented by the client.
Assembly: System (in System.dll)
The User-Agent header typically contains text that identifies the name and version number of the software used to generate the request.
For a complete list of request headers, see the HttpRequestHeader enumeration.
The UserAgent is null when there is no User-Agent header in the request.
The following code example demonstrates using this property.
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); }
