Cursor.Dispose Method

Definition

Releases all resources used by the Cursor.

C#
public void Dispose ();

Implements

Examples

The following code example draws the specified cursor on the form in its normal size, and in stretched mode, twice its size. This example requires a Form and a Cursor to pass into the method when it is called.

C#
private void DrawCursorsOnForm(Cursor cursor)
{
   // If the form's cursor is not the Hand cursor and the 
   // Current cursor is the Default, Draw the specified 
   // cursor on the form in normal size and twice normal size.
   if(this.Cursor != Cursors.Hand & 
     Cursor.Current == Cursors.Default)
   {
      // Draw the cursor stretched.
      Graphics graphics = this.CreateGraphics();
      Rectangle rectangle = new Rectangle(
        new Point(10,10), new Size(cursor.Size.Width * 2, 
        cursor.Size.Height * 2));
      cursor.DrawStretched(graphics, rectangle);
        
      // Draw the cursor in normal size.
      rectangle.Location = new Point(
      rectangle.Width + rectangle.Location.X, 
        rectangle.Height + rectangle.Location.Y);
      rectangle.Size = cursor.Size;
      cursor.Draw(graphics, rectangle);

      // Dispose of the cursor.
      cursor.Dispose();
   }
}

Remarks

Call Dispose when you are finished using the Cursor. The Dispose method leaves the Cursor in an unusable state. After calling Dispose, you must release all references to the Cursor so the garbage collector can reclaim the memory that the Cursor was occupying. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

Notes

Always call Dispose before you release your last reference to the Cursor. Otherwise, the resources it is using will not be freed until the garbage collector frees it.
