[C#]圖形比對

public static bool ImageCompareString(Bitmap firstImage, Bitmap secondImage)

{

    MemoryStream ms = new MemoryStream();

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

    String firstBitmap = Convert.ToBase64String(ms.ToArray());

    ms.Position = 0;

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

    String secondBitmap = Convert.ToBase64String(ms.ToArray());

    if (firstBitmap.Equals(secondBitmap))

    {

        return true;

    }

    else

    {

        return false;

    }

}

使用範例"指定路徑圖片判斷是否一致"

PictureBox pb = new PictureBox();

PictureBox pb2 = new PictureBox();

string str = Directory.GetCurrentDirectory() + "\\1.jpg";

string str2 = Directory.GetCurrentDirectory() + "\\2.jpg";

pb.Load(str);

pb2.Load(str2);

Bitmap bmp1 = new Bitmap(pb.Image);

Bitmap bmp2 = new Bitmap(pb2.Image);

bool Result = false;

Result = ImageCompareString(bmp1, bmp2);
