C ＃ picture display occupancy problem

  Control

  pictureBox1.Image = Image.FromFile("1.jpg");

No problem in actual use , But the picture will be occupied , Not even delete .

After image assignment pictureBox1 It will not refresh immediately , If released immediately image.Dispose() It will cause the back of the picture pictureBox1 An error is reported when the resource is not found during refresh . So refresh the image control before releasing pictureBox1.Refresh()  that will do Release files .

The implementation is as follows ：

var image  = Image.FromFile("1.jpg");

pictureBox1.Image = image;

pictureBox1.Refresh();

image.Dispose();
