C # struct traps in languages

Suppose we want to write a salary management program for a university. First, it indicates the Employee's Employee class (Employee. cs ):

01: namespace Skyiv. ben02: {03: class Employee04: {05: public string Department {get; private set;} 06: public string Name {get; private set;} 07: public decimal Salary {get; set;} 08: 09: public Employee (string department, string name, decimal salary) 10: {11: Department = department; 12: Name = name; 13: Salary = salary; 14:} 15: 16: public override string ToString () 17: {18: return string. format ("{0} {1} Salary: {2: N2}", Department, Name, Salary); 19:} 20:} 21 :}

Next, the Department class (Department. cs) of each Department in the school ):

01: namespace Skyiv. ben02: {03: class Department04: {05: public string Name {get; private set;} 06: public int Count {get; private set;} 07: public decimal TotalSalary {get; private set;} 08: 09: public Department (string name) 10: {11: Name = name; 12:} 13: 14: public void Add (Employee) 15: {16: Count ++; 17: TotalSalary + = employee. salary; 18 :}19: 20: public override string ToString () 21: {22: return string. format ("{0} Total number of students: {1} total salary: {2: N2}", Name, Count, TotalSalary); 23:} 24:} 25 :}

Finally, the main Program. cs:

01: using System; 02: using System. collections. generic; 03: 04: namespace Skyiv. ben05: {06: class Program07: {08: static void Main () 09: {10: new Program (). run (); 11 :}12: 13: void Run () 14: {15: var employees = InitializeEmployees (); 16: SalaryRaise (employees); 17: statistic (employees); 18:} 19: 20: List <Employee> InitializeEmployees () 21: {22: var employees = new List <Employee> (); 23: employees. add (new Employee ("", "", 72767.58 m); 24: employees. add (new Employee (
