大家好我创建10个按钮并添加我的面板。其作品。我想再次点击按钮时更改button.background颜色，我想要转动相同的颜色。 THA

  private void Form1_Load(object sender, EventArgs e)

        {
            Button button = new Button();
            button.Size = new Size(43, 43);
            button.Tag = i;
            button.Click += new EventHandler(ButtonClickOneEvent);
           button.Location = new Point(60, 60 + (i * 50));
          }
            this.panel1.Controls.Add(button);

                        button.BackColor = Color.White;
                    }
                    else
                    {
                        button.BackColor = Color.Red;
                    }
                    break;
                case 1:
                    button.BackColor = Color.Red;
                    break;
                case 3:
                    button.BackColor = Color.Red;
                    break;
            }
        }

    }

如果您想要的是在每次点击鼠标时更改背景颜色，您可以执行以下操作：

void ButtonClickOneEvent(object sender, EventArgs e)
{
    Button btn = sender as Button;
    if (btn != null)
    {
         btn.BackColor = (btn.BackColor == Color.White) ? Color.Red : Color.White;
    }
}

单击后更改按钮背面颜色，并在第二次单击后将其更改回来，依此类推
