this.button_name.BackgroundColor = your_color_name_here; //get from enumeration :)

Button button = this.FindControl("name_of_yourcontrol");
button.BackgroundColor = your_color_here; //get from enumeration

希望对您有所帮助:)

Hope it helps :)

假设您的按钮名为btnRed, btnBlue, btnGreen，依此类推，然后您更改了表单的背景色，只需添加一个通用的Click事件处理程序即可:

Supposing that your buttons are named btnRed, btnBlue, btnGreen, and so on, and you change the background color of the form, just add a common Click event handler:

void ColorButtonClick(object sender, EventArgs e)
{
    this.BackColor = Color.FromName((sender as Button).Name.Substring(3));
}

private List<string> GetAllButtonNames()
{
    return (from ctrl in this.Controls.OfType<Button>() 
                              select ctrl.Name).ToList();
}
