Override .ToString method c# -

okay, wrote program out of exercise of c# programming book (i'm trying learn here) , asks "override tostring() method return data members".

have done correctly? or have wrote code compiles nothing. purpose of tostring?

i have spent 30 minutes looking @ other posts on , havn't figured out, decided make this.

using system; using system.collections.generic; using system.linq; using system.text;  namespace consoleapplication297 { class program {     static void main(string[] args)     {         string name = "stormtrooper";         employee s = new employee(name);         console.writeline("the type of hire {0}", s.name);         console.writeline("the identification number {0}", s.number);         console.writeline("the date of hire {0} aby", s.date);         console.writeline("the standard galactic salary is...{0:c}", s.salary);      }      class employee     {         private string _name;         private string _number;         private int _date;         private int _salary;         public string name         {                         {                 return _name;             }         }          public string number         {                         {                 return _number;             }         }          public int date         {                         {                 return _date;             }         }         public int salary         {                         {                 return _salary;             }         }         public employee(string n)         {             _name = n;             _number = "aa23tk421";             _date = 4;             _salary = 800;         }     }      public override string tostring()      {         return "_name + _number + _date + _salary".tostring();     } } } 

you returning string says phrase _name + _number + _date + _salary.

what wanted build string using fields. if wanted them mushed concat work, highly un-readable

public override string tostring() {     return string.concat(_name, _number, _date, _salary); } 

however better use format , include labels values

public override string tostring() {     return string.format("name: {0}, number:{1}, date:{2}, salary:{3}",_name, _number, _date, _salary); }
