How to get windows user ID in C# web application?<br />
To clarify, I am talking about login ID that user uses to login to his working machine. (he/she has to press Ctrl-Alt-Del and enter login and password to start working)<br />
<br />
I was looking around and &nbsp;one of the suggestion was to use: &nbsp;System.Environment.UserNam<wbr />e;<br />
But, this gives (by my opinion) account name under which the application is logged to the server that hosts application. In my case I get &quot;ASPNET&quot; and that is not my windows ID.<br />
<br />
I assume that for this I will have to connect to Active Directory. How can I do that and how to query Active Directory. Thanks.<br />

How to get windows user ID in C# web application (asp.net 2.0)?

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
