推荐答案

我要做一些假设



1.您正在将单个图像与多个图像进行比较。

2.比较是两个图像的字节到字节比较。

3.图像的格式相同。



然后

I''m going to make some assumptions

1. You are comparing a single image with a number of images.
2. The comparison is a byte-to-byte comparison of two images.
3. Images are in the same format.

Then

foreach image in database
    {
    images_equal = true
    if ( image.Size != uploaded_image.Size )
        {
        images_equal = false
        }
    else
        {
        foreach byte in the images
            {
            if ( image_byte != uploaded_image_byte )
                {
                images_equal = false
                break
                }
            }
        }
    if ( images_equal )
        {
        do something with equal images
        }
    else
        {
        do something with unequal images
        }
    }

字节到字节的比较可能需要是System.Runtime.InteropServices。

The byte to byte comparison may require System.Runtime.InteropServices.
