Hi there i need to show/hide a button in form1 based on user roles,

If Logedin User = Administrator then

btn1.show
else

hide

how do i do this?

I found this on the web but not good:

Code:

 
String sddlAdmins = "S-1-5-32-544";  //Sid of administrators group
IdentityReference AdminsSid = new SecurityIdentifier(sddlAdmins);
 
WindowsIdentity wid = new WindowsIdentity(Environment.UserName);
_isAdministrator = wid.Groups.Contains(AdminsSid);
 
if (_isAdministrator)
    Console.WriteLine(Environment.UserName + " is running with admin rights!");

_is Administrator is not defined

thanks
