Image 转成 byte 的问题？

[sqlaqandy]

byte[] byteImage;
Image img = picBox.Image;
MemoryStream mem = new MemoryStream();
img.Save(mem, System.Drawing.Imaging.ImageFormat.Jpeg);
byteImage = mem.ToArray();
MemoryStream mem2 = new MemoryStream();
mem2.Read(byteImage, 0, byteImage.Length);
pictureBox1.Image = Image.FromStream(mem2); //这里报“无效的参数”

在
img.Save(mem, System.Drawing.Imaging.ImageFormat.Jpeg);
之后加上
mem.Flush();

[Knight94]

Sample code as follows:
byte[] byteImage;
Image img = picBox.Image;
MemoryStream mem = new MemoryStream();
img.Save(mem, System.Drawing.Imaging.ImageFormat.Jpeg);
mem.Flush();
byteImage = mem.ToArray();
MemoryStream mem2 = new MemoryStream( byteImage, true );
mem2.Read(byteImage, 0, byteImage.Length);
pictureBox1.Image = Image.FromStream(mem2);
