The improvement of C # Singleton

public class Singleton
{
private static BOOL Instance_flag=false;instance flag useless, directly determine whether there are instances of instance can solve this problem.
private static Singleton instance;
public string name;
Private Singleton ()//Changes the Singleton function to private, preventing it from being called directly to create it.
{
Name= "Guqi";
Console.WriteLine ("You can only see me once!");
}
public static Singleton getinstance ()
{
if (instance==null)
{

Instance_flag=true;
Instance=new Singleton ();
return instance;
}
else return instance;
}
}

Thanks for vb1980 's code improvements.

public static Singleton getinstance ()
{
if (instance==null)
{
Instance=new Singleton ();
}
return instance;
}
Much simpler.
