C# 捕获鼠标
方式一-API
/// <summary>
/// 捕获鼠标
/// </summary>
/// <param name="hwnd"></param>
/// <returns></returns>
[DllImport("user32.dll", SetLastError = true)]
public static extern bool SetCapture(IntPtr hwnd);
/// <summary>
/// 释放鼠标
/// </summary>
/// <returns></returns>
[DllImport("user32.dll", SetLastError = true)]
public static extern bool ReleaseCapture()方式二
Control.Capture;
通过捕获鼠标改变指针
Cursor cursor;
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
Bitmap bitmap = Properties.Resources._111;
cursor = new Cursor(bitmap.GetHicon());
pictureBox1.Cursor = cursor;
SetCapture(pictureBox1.Handle);
bitmap.Dispose();
}
private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
cursor.Dispose();
ReleaseCapture();
pictureBox1.Cursor = Cursors.Default;
