Environment::UserDomainName Property

Gets the network domain name associated with the current user.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public:
static property String^ UserDomainName {
	String^ get ();
}

Property Value

Type: System::String
The network domain name associated with the current user.
ExceptionCondition
PlatformNotSupportedException

The operating system does not support retrieving the network domain name.

InvalidOperationException

The network domain name cannot be retrieved.

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 without the user name, and the UserName property to obtain the user name without the domain name. For example, if a user's domain name and user name are CORPORATENETWORK\john, the UserDomainName property returns "CORPORATENETWORK".

The UserDomainName property first attempts to get the domain name component of the Windows account name for the current user. If that attempt fails, this property attempts to get the domain name associated with the user name provided by the UserName property. If that attempt fails because the host computer is not joined to a domain, then the host computer name is returned.

Windows 95, Windows 98, Windows 98 Second Edition, Windows Millennium Edition Platform Note: The UserDomainName property is not supported for this platform.
