Namespace:  System.Net.NetworkInformation
Assembly:  System (in System.dll)

public abstract string DomainName { get; }

Property Value

Type: System.String
A String instance that contains the computer's domain name. If the computer does not belong to a domain, returns Empty.


A Win32 function call failed.

The DomainName property returns the domain in which the local computer is registered.

If a local computer is registered in a domain and then changes to a workgroup, the DomainName property still returns the previous domain name not the Empty.

The following code example displays network information for the local computer.

IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
Console.WriteLine("Computer name: {0}", properties.HostName);
Console.WriteLine("Domain name:   {0}", properties.DomainName);
Console.WriteLine("Node type:     {0:f}", properties.NodeType);
Console.WriteLine("DHCP scope:    {0}", properties.DhcpScopeName);
Console.WriteLine("WINS proxy?    {0}", properties.IsWinsProxy);
