I have browsed and uploaded a png/jpg file in my MVC web app. I have stored this file as byte[] in my database. Now I want to read and convert the byte[] to original file. How can i achieve this?

推荐答案

1. 创建 MemoryStream ，将数组传递给构造函数.
2. 使用 Image.FromStream从流中读取图像.
3. 致电 theImg.Save("theimage.jpg"，ImageFormat.Jpeg).

1. Create a MemoryStream passing the array in the constructor.
2. Read the image from the stream using Image.FromStream.
3. Call theImg.Save("theimage.jpg", ImageFormat.Jpeg).

记住要引用System.Drawing.Imaging，并为流使用 using 块.

Remember to reference System.Drawing.Imaging and use a using block for the stream.
