//图片转二进制流
private byte[] PictureToByte(string picturePath)
{
FileStream fs = new FileStream(picturePath, FileMode.Open);
byte[] streamByte = new byte[fs.Length];
fs.Read(streamByte, 0, streamByte.Length);
fs.Close();
return streamByte;
}
//二进制流转图片
private System.Drawing.Image ByteToPicture(byte[] streamByte)
{
System.IO.MemoryStream ms = new System.IO.MemoryStream(streamByte);
System.Drawing.Image img = System.Drawing.Image.FromStream(ms);
return img;
}
把这两幅图片转换成二进制，在比较
