A Simple ASP.NET program for detecting browser type that clients use

Download source - 0.56 Kb

This article intends to show how to detect the browser on the clients side. I use the HttpBrowserCapabilities class using the C# language. The HttpBrowserCapabilities class gives information on the capabilities of the browser that is running on the client. It needs the System.Web namespace. HttpBrowserCapabilities properties are accessible through the Browser property of ASP.NET's intrinsic
