How do I detect if the left mouse button is being held down in the OnMouseMove event for a control?

推荐答案

您事件处理程序的的OnMouseMove事件应该免费获赠 MouseEventArgs 应该告诉你，如果按下左键

Your eventhandler for the OnMouseMove event should recieve a MouseEventArgs that should tell you if the left button is pressed

private void mouseMoveEventHandler(object sender, MouseEventArgs e)
{
   if(e.Button == MouseButtons.Left)
   {
     //do left stuff
   }
   else
   {
     // do other stuff
   }
}
