在C#中,鼠標滾輪事件和鼠標移動事件可以通過以下方式關聯:
public Form1()
{
InitializeComponent();
this.MouseWheel += new MouseEventHandler(Form1_MouseWheel);
}
private void Form1_MouseWheel(object sender, MouseEventArgs e)
{
MessageBox.Show("Mouse wheel has been scrolled.");
}
public Form1()
{
InitializeComponent();
this.MouseMove += new MouseEventHandler(Form1_MouseMove);
}
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
MessageBox.Show("Mouse has been moved.");
}
private void Form1_MouseWheel(object sender, MouseEventArgs e)
{
MessageBox.Show("Mouse wheel has been scrolled.");
Form1_MouseMove(sender, e);
}
這樣,當鼠標滾輪滾動時,鼠標移動事件處理程序將被調用,從而實現了鼠標滾輪事件與鼠標移動事件的關聯。
