我试图在窗体上的某些按钮之间创建某种联系,这样当我单击一个按钮时,它会突出显示所有以前的按钮[某种音量控制器]
想象一下它是一个音量控制器.所有这些彩色按钮都是灰色的,我想要实现的是当你点击一个按钮时,它会将所有按钮着色;然而IDK在不涉及大量无用代码的情况下制作这样的行为的最佳方式是什么…
解决方法
首先,您需要将所有按钮添加到数组中,然后从那里处理它
码
//Create an array of buttons and hook up the Click event of each of them
private Button[] VolumeButtons { get; set; }
public Main()
{
InitializeComponent();
//Assuming that you have 21 buttons as it appears in your picture...
VolumeButtons = new Button[21];
VolumeButtons[0] = button1;
VolumeButtons[1] = button2;
VolumeButtons[2] = button3;
VolumeButtons[3] = button4;
VolumeButtons[4] = button5;
VolumeButtons[5] = button6;
VolumeButtons[6] = button7;
VolumeButtons[7] = button8;
VolumeButtons[8] = button9;
VolumeButtons[9] = button10;
VolumeButtons[10] = button11;
VolumeButtons[11] = button12;
VolumeButtons[12] = button13;
VolumeButtons[13] = button14;
VolumeButtons[14] = button15;
VolumeButtons[15] = button16;
VolumeButtons[16] = button17;
VolumeButtons[17] = button18;
VolumeButtons[18] = button19;
VolumeButtons[19] = button20;
VolumeButtons[20] = button21;
foreach (var volumeButton in VolumeButtons)
volumeButton.Click += VolumeButton_Click;
}
void VolumeButton_Click(object sender,EventArgs e)
{
//Find the index of the clicked button
int index = Array.FindIndex(VolumeButtons,VolumeButtons.Length,button => button == ((Button)sender));
//Set the color of all the prevIoUs buttons to Aqua,and all the forward buttons to gray [ you may play with it to match your colors then ]
for (int i = 0; i < VolumeButtons.Length; i++)
VolumeButtons[i].BackColor = i <= index ? Color.Aqua : Color.Gray;
}
