Here's an example (WPF):

这是一个例子（WPF）：

public MainWindow()
{
    InitializeComponent();
    this.MouseMove += new MouseEventHandler(MainWindow_MouseMove);
}

void MainWindow_MouseMove(object sender, MouseEventArgs e)
{
    if (e.LeftButton == MouseButtonState.Pressed)
    {
        //do something
    }
}
