利用net5实现图片格式的相互转换

Image image = BytesToImage(buffer);

MemoryStream ms = new MemoryStream();

image.Save(ms, System.Drawing.Imaging.ImageFormat.Png);

var bmp = BytesToImage(ms.ToArray());

ImageFormat format = bmp.RawFormat;

if (format.Equals(ImageFormat.Jpeg))

{

}

 else if (format.Equals(ImageFormat.Png))

 {

}

else if (format.Equals(ImageFormat.Bmp))

{

}

else if (format.Equals(ImageFormat.Gif))

{

}

else if (format.Equals(ImageFormat.Icon))

 {

 }

 /// <summary>

/// Convert Byte[] to Image

/// </summary>

 /// <param name="buffer"></param>

/// <returns></returns>

public static Image BytesToImage(byte[] buffer)

 {

            MemoryStream ms = new MemoryStream(buffer);

            Image image = System.Drawing.Image.FromStream(ms);

            return image;

 }
