由于需要写了几个自定义控件，步骤如下：
1.创建N个UserControl，分别放一个PictrueBox控件，然后导入本地图片。
2.将自定义控件拖入一个WinForm窗体上，并在控件的Click事件中分别入如下代码以做测试：
private void yesButton1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is A YesButton !", "Test UserControls");
}
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is A SystemButton !", "SystemControl");
}
private void noButton1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is A NoButton !", "Test UserControls");
}
private void cancelButton1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is A CancelButton !", "Test UserControls");
}
private void returnButton1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is A ReturnButton !", "Test UserControls");
}
private void communicationButton1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is A CommunicationButton !", "Test UserControls");
}
结果编译器自带的button可以触发Click事件，我自己写的控件触发不了Click事件是怎么回事呢，请有经验的朋友帮忙，在线等！
