How to make number Count in loop in c#? -

this simple begginer program setter , getter concept have make first enter user name , password welcomed , if enter wrong info should display invalid , 5 tries left if again enter wrong info should display 4 tries left , on , when tries on should hang program or lock screen or

using system;   namespace consoleapplication4 {     class program     {         static void main(string[] args)         {             demo obj = new demo();             string uname, pass;             console.foregroundcolor = consolecolor.green;         label1:             console.clear();             console.writeline("enter username");             uname = console.readline();             console.writeline("enter password");             pass = console.readline();             obj.setname(uname);             obj.setpass(pass);             if (obj.getname() == "niit")             {                 if (obj.getpass() == "1234")                 {                     console.writeline("welcome");                  }             }             else             {                 console.clear();                 console.writeline("invalid");                 console.writeline("\n \n \n try again enter y");                 int n = 5;                 string yes = console.readline();                     if (yes == "y")                 {                     while (n >= 1)                     {                         console.write(n + " tries left");                         goto label1;                         n = --n;                     }                 }             }              console.readkey();          }     }     class demo     {         private string name, pass;         public void setname(string name)         {             this.name = name;         }         public string getname()         {             return name;         }         public void setpass(string pass)         {             this.pass = pass;         }         public string getpass()         {             return pass;         }     } } 

please suggest simple begginers code make loop work , make count down

a while loop should suffice. using boolean detect successful password entry. when entered, break out of loop. invalid attempts decrement attemptsleft int. note: haven't tried in visual studio, logic should sound, recommend debugging , stepping through test if meets criteria.

static void main(string[] args)     {         demo obj = new demo();         string uname, pass;         console.foregroundcolor = consolecolor.green;     label1:         console.clear();         console.writeline("enter username");         uname = console.readline();         console.writeline("enter password");        bool successfulpassword = false;        int attemptsleft = 5;         while(!successfulpassword && attemptsleft > 0){         pass = console.readline();         obj.setname(uname);         obj.setpass(pass);         if (obj.getname() == "niit")         {             if (obj.getpass() == "1234")             {                 console.writeline("welcome");                 successfulpassword = true;             }         }         else         {             attemptsleft--;             console.clear();             console.writeline("invalid");             console.writeline("\n \n \n try again enter y");             int n = 5;             string yes = console.readline();                 if (yes == "y")             {                      console.write(attemptsleft + " tries left");             }         }          console.readkey();         }     }
