c#中将image类型转换成字节

[Waldenz]

c#中将image类型转换成字节存进数据库中
但不用路径
主要问题是:
就是数据中的一个image对象
我怎么转换成字节

[兔子-顾问]

Image img = Image.FromFile("文件名");
MemoryStream ms = new MemoryStream();
img.Save(ms, img.RawFormat);
byte[] data = ms.ToArray();//<--data

        /// <summary>
        /// 图像转换为Byte数组
        /// </summary>
        private byte[] imageToByteArray(Image imageIn)
        {
            MemoryStream ms = new MemoryStream();
            imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Icon);
            return ms.ToArray();
        }

        /// <summary>
        /// Byte数组转换为图像
        /// </summary>
        private Image byteArrayToImage(byte[] byteArrayIn)
        {
            MemoryStream ms = new MemoryStream(byteArrayIn);
            Image returnImage = Image.FromStream(ms);
            return returnImage;
        }

            Image i = Image.FromFile(@"c:\路径\图片.jpg");
            MemoryStream s = new MemoryStream();
            i.Save(s, System.Drawing.Imaging.ImageFormat.Jpeg);
            byte[] b = s.ToArray();

试试看

System.IO.FileStream stream = new FileStream(FilePath, FileMode.Open, FileAccess.Read)
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, (int)stream.Length);

[wuyq11]

using(MemoryStream ms = new MemoryStream())
{
pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
ms.Position = 0;
byte[] imageBytes = new byte[ms.Length];
ms.Read(imageBytes,0,imageBytes.Length);
}
Image img = Image.FromStream(new MemoryStream(buffer));//buffer为byte数组

[Quote=引用 1 楼 wuyazhe 的回复:]
C# code
Image img = Image.FromFile("文件名");
MemoryStream ms = new MemoryStream();
img.Save(ms, img.RawFormat);
byte[] data = ms.ToArray();//<--data
[/Quote]
IO行的.

我说过不用路径的
用二楼的解决了
多谢了
