示例1: DemonstratePropertyItem
private void DemonstratePropertyItem(PaintEventArgs e)
{
// Create two images.
Image image1 = Image.FromFile("c:\\FakePhoto1.jpg");
Image image2 = Image.FromFile("c:\\FakePhoto2.jpg");
// Get a PropertyItem from image1.
PropertyItem propItem = image1.GetPropertyItem(20624);
// Change the ID of the PropertyItem.
propItem.Id = 20625;
// Set the PropertyItem for image2.
image2.SetPropertyItem(propItem);
// Draw the image.
e.Graphics.DrawImage(image2, 20.0F, 20.0F);
