如何动态地向我的表单添加按钮? [英] How to add buttons dynamically to my form?

问题描述

当我单击 button1 时，我想在表单上创建 10 个按钮.下面这段代码没有错误，但它也不起作用.

I want to create 10 buttons on my form when I click on button1. No error with this code below but it doesnt work either.

private void button1_Click(object sender, EventArgs e)
{
    List<Button> buttons = new List<Button>();
    for (int i = 0; i < buttons.Capacity; i++)
    {
        this.Controls.Add(buttons[i]);   
    }
}

推荐答案

它不起作用，因为列表为空.试试这个:

It doesn't work because the list is empty. Try this:

private void button1_Click(object sender, EventArgs e)
{
    List<Button> buttons = new List<Button>();
    for (int i = 0; i < 10; i++)
    {
        Button newButton = new Button();
        buttons.Add(newButton);
        this.Controls.Add(newButton);   
    }
}
