How Can I Programmatically Simulate Mouse Movement in C#?

Use C# to simulate mouse movement

Question:

How to programmatically move the mouse cursor on the screen periodically?

Answer:

To control the movement of the mouse cursor using C#, you can use the Cursor.Position attribute. Here is an example of a method that moves the cursor 50 pixels left and up.

<code class="language-csharp">private void MoveCursor()
{
    // 设置当前光标，移动光标的位置，
    // 并将其剪裁矩形设置为窗体。
    this.Cursor = new Cursor(Cursor.Current.Handle);
    Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
    Cursor.Clip = new Rectangle(this.Location, this.Size);
}</code>

Example usage:

To simulate mouse movement every "x" seconds, use a timer with an interval of "x" milliseconds. When the timer ticks, call the MoveCursor method to move the cursor.

<code class="language-csharp">private void StartMouseMovementSimulation()
{
    // 设置计时器，每隔x秒模拟鼠标移动
    Timer timer = new Timer();
    timer.Interval = x * 1000; // 将x秒转换为毫秒
    timer.Tick += OnTimerTick;
    timer.Start();
}

private void OnTimerTick(object sender, EventArgs e)
{
    // 移动光标
    MoveCursor();
}</code>

Note: x represents the time interval in seconds. In the code, x has been multiplied by 1000 to convert it to milliseconds because the Timer.Interval attribute uses milliseconds as the unit. This code needs to be used in an appropriate form or class, making sure that the necessary using statements (such as using System.Drawing; and using System.Windows.Forms;) have been added. In addition, frequent mouse movements may be detected by the operating system and blocked, please use this feature with caution.
