using System; using System.Reflection; using System.Collections.Generic; delegate void ComputeDelegate<T>( T instance, Decimal percent ); public class Employee {     public Decimal Salary;     public Employee( Decimal salary ) {         this.Salary = salary;     }     public void ComputeSalary( Decimal percent ) {         Salary *= (1 + percent);     } } public class MainClass {     static void Main() {         List<Employee> employees = new List<Employee>();         employees.Add( new Employee(40) );         employees.Add( new Employee(65) );         employees.Add( new Employee(95) );         MethodInfo mi = typeof(Employee).GetMethod( "ComputeSalary", BindingFlags.Public | BindingFlags.Instance );         ComputeDelegate<Employee> applyRaise = (ComputeDelegate<Employee> )Delegate.CreateDelegate(typeof(ComputeDelegate<Employee>), mi );         foreach( Employee e in employees ) {             applyRaise( e, (Decimal) 0.10 );             Console.WriteLine( e.Salary );         }     } } 44.0 71.5 104.5
