How to get the current Windows User Account Name efficiently?

I am trying to get "current active user account name" (Windows user).

For that I have tried the below mentioned code and I get the "current active user account name", but this code first get all users list and then filters (get) the "current active user name".

Now, I am trying to get "current active user account name" (Windows user) but without a for loop and I tried to get help (research) in Microsoft Developer Documentation but I could not able to find helpful resources.

SelectQuery userListQuery = new SelectQuery("Win32_UserAccount");
ManagementObjectSearcher userSearcher = new ManagementObjectSearcher(userListQuery);

foreach (ManagementObject envVar in userSearcher.Get())
{
    // get sid string from username (for to acsess user's current_user registry key)
    NTAccount userAccount = new NTAccount(envVar["Name"].ToString());
    SecurityIdentifier sid = (SecurityIdentifier)userAccount.Translate(typeof(SecurityIdentifier));
    string sidString = sid.ToString();

    File.AppendAllText("c:\\outs\\log.txt", " ---- user account  ----" + userAccount + "\n\n");
    File.AppendAllText("c:\\outs\\log.txt", " ---- sid string  ----" + sidString + "\n\n");
}

I've solved my problem using:

var searcher = new ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem");
var collection = searcher.Get();
string username = (string)collection.Cast<ManagementBaseObject>().First()["UserName"];
