一:转换为byte[]
1.将Bitmap转换为二进制流
public static byte[] Bitmap2Byte(Bitmap bitmap) { using (MemoryStream stream = new MemoryStream()) { bitmap.Save(stream, ImageFormat.Jpeg); byte[] data = new byte[stream.Length]; stream.Seek(0, SeekOrigin.Begin); stream.Read(data, 0, Convert.ToInt32(stream.Length)); return data; } }
二:将byte[]转换为其他
1.将byte[]转换为字符串
string res = System.Text.Encoding.Default.GetString(byteArr);
