代替使用array of delegate的，使用multicast delegate。更改main方法如下。

student s1 = new student(); 
method d;       
d = new method(s1.Setpersonalinfo);    
d += new method(s1.setcourseinfo); 
d += new method(s1.setgpa);    
d += new method(s1.getpersonalinfo); 
d += new method(s1.getcourseinfo); 
d += new method(s1.getgpa); 

for (int i = 0; i < 2;i++) 
     d(); 

Console.ReadKey();
