Question

I need to get the username who logged in particular machine in my LAN. Suggest me a best method to get the user name by passing machine name in C#.net windows application. Also consider the permission.

Answer 1

//How about this:
string strUserName = WindowsIdentity.GetCurrent().Name;

You can then do whatever you want to do with that "strUserName" variable. Please note it also contains the Domain Name if one is present.

Answer 2

Hi All I got the solution for my question. I used WMI to get the userName.

try {
    object[] objArr = new object[2];
    ManagementScope ms = new ManagementScope("Path");
    ms.Connect();
    if (ms.IsConnected)
    {
        ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_Process WHERE Name='explorer.exe'");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(ms, Query);
        foreach(ManagementObject objQuery in searcher.Get())
        {
            objQuery.InvokeMethod("GetOwner", objArr); // objArr[0] contains the userId and objArr[1] contains Domainname
            userName = Convert.ToString(objArr[0]);
        }
    }
}
catch (System.Exception ex)
{
    throw ex;
}

Thanks
