Found that Baidu is also not a problem, some people irrelevantly replying lead to learning atmosphere a mess, so write a little basic needs comrade can refer to

  Private voidButton1_Click (Objectsender, EventArgs e) {            int[] num=New int[6]; num[0] =0; num[1] =1; num[2] =2; num[3] =3; num[4] =4; stringres =string.            Empty;  for(inti =0; I < Num. Length; i++) {res+ = Num[i] +","; }             This. Label1. Text ="before inserting:"+Res; stringRes1 =string.            Empty;  for(inti =0; I < Num. Length; i++) {res+=Num[i]; if(i = =2)                {                     for(intj = Num. length-1; J >2; j--)                    {                        if(J <6) {Num[j]= Num[j-1]; }} num[2] =int. Parse ( This. TextBox1.Text);  Break; }            }             for(inti =0; I < Num. Length; i++) {res1+ = Num[i]. ToString () +","; }             This. Label2. Text ="after insertion:"+res1; }
