c# - How make arrays of delegates and use this array? -

i have write class eve make code below:

class mainclass   {    int sum = 5;     public  void add (int x)     {       sum += x;     }     public static void write (int x)     {       console.writeline("x = " + x);     }     public static void main (string[] args)     {       eve p = new eve();       mainclass m = new mainclass();        p.registrate(m.add);       p.registrate(write);       p.registrate (delegate (int x) {                        system.console.writeline(" have {0} ", x);                     });        p.registrate (x => system.console.writeline (" square : {0} ", x * x));       p.run(10);       p.run(5);                   console.writeline(" sum {0} ", m.sum);     }   } 

output:

x = 10

i have 10

square : 100

x = 5

i have 5

square : 25

sum 20

so think have use delegates. , method registarte should add delegate array of delegates.

i wrote code dint sure wright.

 public class eve     {         int i;         public eve()         {             = 0;         }         public delegate void computedelegate(int x);          computedelegate[] delegates = new computedelegate[2];          public void registrate(computedelegate a)         {             if (i == 2) = 0;             delegates[i] += a;             i++;         }          public void run()         {             //delegates[0].;         } }         public class mainclass         {             int sum = 5;             public void add(int x)             {                 sum += x;             }             public void write(int x)             {                 console.writeline("x = " + x);             }             static void main()             {                 eve proc1 = new eve();                 mainclass m = new mainclass();                  proc1.registrate(m.add);                 proc1.registrate(m.write);               }         }     } 

i have problem how have write method run? or same in way how can lunch method wich in delegate array?

it looks need delegates[0](x); x int want pass 0th entry in array.

(delegates has type computedelegate[]. computedelegate type has same signature , return type system.action<int>, of course.)
