数组的初始化方式

 

举例说明：

Person p1=new Person("a","b");

        Person p2 = new Person("c", "d");

        Person p3 = new Person("e", "f");

        Person[] ap1=new Person[]{p1,p2,p3};

        //相当于：

        //1、Person[] ap1= {p1,p2,p3};

        //2、Person [] ap1=new Person[3]; ap1= {p1,p2,p3};

　　　　//3、Person[]ap1=new Person[3] {p1,p2,p3};

        //4、Person []ap1=new Person[];ap1= {p1,p2,p3};

 

Person[] ap2=new Person[6];

        Array.Copy(ap1, ap2, 2);

        foreach (Person p in ap2)

        {

            if(p!=null)

            {

                Response.Write(p.Fullname + "</br>");

            }

        }
