一：将Image类转换成Bitmap类

1 System.Drawing.Image img = System.Drawing.Image.FromFile(filepath);
2 System.Drawing.Image bmp = new System.Drawing.Bitmap(img);
3 img.Dispose();

然后使用 bmp作为PictureBox的图片源
二：从流中读取

1 FileStream fileStream = new FileStream("文件名", FileMode.Open, FileAccess.Read);
2 pictureBox1.Image = Image.FromStream(fileStream);
3 fileStream.Close();
4 fileStream.Dispose();
