谁说的?您是否看过我在此部分中共享的链接:按钮数组的通用事件处理程序 [ ^ ]

i have found lots of answers for dynamic arrays,but i cant implement it for a button array.
Who said so? Did you look at this link I shared, here this section: Creating a Common Event Handler for a button array[^]

您修改后的代码应该可以工作:

Hi,
this modified code of yours should work:

private Button[] bu = new Button[12];
public static int index1;
public int[] ar = new int[4];
public string[] cl1 = new string[4];
index1 = 0;
           {
            x = 30;
            for (int i = 0; i < ar.Length; i++)
            {
                bu[index1] = new Button();
                bu[index1].Location = new Point(50, x);
                bu[index1].Size = new Size(75, 20);
                bu[index1].Text = "1";
                bu[index1].Click += new EventHandler(button_Click);
                cl1[i] = "b" + i;//name the buttons @ the 1st column
                lable[index1] = new Label();
                lable[index1].Location = new Point(75,(x+25));
                lable[index1].Size = new Size(35, 13);
                //lable[index1].Text = Convert.ToString(cl1[i]);
                bu[index1].Name = Convert.ToString(cl1[i]);
                lable[index1].Text = bu[index1].Name;
                x = x + 100;
                index1++;
            }
            this.Controls.AddRange(bu);
            this.Controls.AddRange(lable);
        }

        private void button_Click(object sender, EventArgs e)
        {
            MessageBox.Show("You hv cast ur vote for the 1ft preference");
        }
