Environment::UserName Property

Gets the user name of the person who is currently logged on to the Windows operating system.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public:
static property String^ UserName {
	String^ get ();
}

Property Value

Type: System::String
The user name of the person who is logged on to Windows.

You can use the UserName property to identify the user on the current thread, to the system and application for security or access purposes. It can also be used to customize a particular application for each user.

The UserName property wraps a call to the Windows GetUserName function. The domain account credentials for a user are formatted as the user's domain name, the '\' character, and user name. Use the UserDomainName property to obtain the user's domain name and the UserName property to obtain the user name.

If an ASP.NET application runs in a development environment, the UserName property returns the name of the current user. In a published ASP.NET application, this property returns the name of the application pool account (such as Default AppPool).

The following example displays the user name of the person who started the current thread.

// Sample for the Environment::UserName property 
using namespace System;
int main()
{
   Console::WriteLine();

   //  <-- Keep this information secure! -->
   Console::WriteLine( "UserName: {0}", Environment::UserName );
}
