推荐答案

下面是如何做到这一点做作的例子。你可能有一些失踪的逻辑被覆盖光标的可见性：

Here is a contrived example of how to do it. You probably had some missing logic that was overriding the cursor's visibility:

public partial class Form1 : Form
{
    public TimeSpan TimeoutToHide { get; private set; }
    public DateTime LastMouseMove { get; private set; }
    public bool IsHidden { get; private set; }

    public Form1()
    {
        InitializeComponent();
        TimeoutToHide = TimeSpan.FromSeconds(5);
        this.MouseMove += new MouseEventHandler(Form1_MouseMove);
    }

    void Form1_MouseMove(object sender, MouseEventArgs e)
    {
        LastMouseMove = DateTime.Now;

        if (IsHidden) 
        { 
            Cursor.Show(); 
            IsHidden = false; 
        }
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        TimeSpan elaped = DateTime.Now - LastMouseMove;
        if (elaped >= TimeoutToHide && !IsHidden)
        {
            Cursor.Hide();
            IsHidden = true;
        }
    }
}
