C＃如何在面板形式加载中显示随机生成器数组按钮 [英] C# how to display a random generator array button in panel form load

问题描述

我有一个随机生成器数组按钮。我希望在表单加载时在面板中显示它...？



我尝试过：

I have a randomly generator array button.i want to display it inside the panel when form load...?

What I have tried:

int maxRows = 10;

            int maxCols = 10;

            Button[,] b_Array = new Button[maxRows, maxCols];

            for (int i = 0; i < maxRows; i++)

            {

                for (int j = 0; j < maxCols; j++)

                {

                    b_Array[i, j] = new Button();

                    b_Array[i, j].Size = new Size(40, 55);

                    b_Array[i, j].Location = new Point(55 + j * 35, 55 + i * 55);

                    this.Controls.Add(b_Array[i, j]);

                }

            }

推荐答案

您展示的代码应该有效：但是它将按钮添加到这个引用，这是包含类的当前实例 - 通常它将是您当前的表单。

要添加只需更改：

The code you show should work: but it adds the buttons to the this reference, which is the current instance of the containing class - normally it will be your current form.
To add them to your panel instead of teh form, just change:

this.Controls.Add(b_Array[i, j]);

收件人：

To:

myPanel.Controls.Add(b_Array[i, j]);

但我这样做的方式略有不同：

But the way I would do it is slightly different:

Button[] buttons = new Button[maxRows * maxCols];
int index = 0;
for (int i = 0; i < maxRows; i++)
    {
    for (int j = 0; j < maxCols; j++)
        {
        Button b = new Button();
        b.Size = new Size(40, 55);
        b.Location = new Point(55 + j * 35, 55 + i * 55);
        buttons[index++] = b;
        }
    }
myPanel.Controls.AddRange(buttons);
