    }
}

所以这是我的一个应用程序的代码，它要求用户提供 2 个图像文件，比较它们，如果相同，它会将这 2 个文件的名称附加到一个无效的文本文件中，如果不同，则不工作'会将 2 个 img 文件的名称附加到名为 WORKING.txt 的文本文件中。

基本上我的问题是用户输入。包含图像的目录包含大约 1100 张图像，第一张图像比较第二张，第三张到第四张，依此类推，

所以我不想手动输入每个图像文件名来将它与第二个文件进行比较，我想遍历整个 MTOImage 目录并比较图像，同时将 similar/different 相机的名称附加到它们的各自的 txt 文件。

我很难自动执行此操作，有人可以帮忙吗？谢谢

我认为您过度使用了静态方法和变量。例如。我会将 equalElements 设为局部变量，这样您就可以使用它更轻松地遍历所有文件：

public int CompareImgSimilarityvalue(String filename1, String filename2)
    {
        List<bool> iHash1 = GetHash(new Bitmap(filename1));
        List<bool> iHash2 = GetHash(new Bitmap(filename2));

        //determine the number of equal pixel (x of 256) 256 is a perfect match
        return iHash1.Zip(iHash2, (i, j) => i == j).Count(eq => eq);

    }

    public static void Analyis()
    {

        string[] files = Directory.GetFiles(@"C:\Users\ChawlaRa\Desktop\FilezilleIMGS\MTO_Image\", "*.jpg");

        Array.Sort(files);

        int equalElements = 0;
        StringBuilder workingText = new StringBuilder();
        StringBuilder notWorkingText = new StringBuilder();


        for (var i = 0; i < (files.Length - 1); i++)
        {
            equalElements = CompareImgSimilarityvalue(files[i], files[i + 1]);



            //if LESS THAN 98% similar
            if (equalElements < 253.44)
            {
                //images different
                Console.WriteLine("NOT Same Images");

                Console.WriteLine("These images below are DIFFERENT - conclusion CAMERA WORKING");
                Console.WriteLine(files[i] + ".jpg");
                Console.WriteLine(files[i+1] + ".jpg");

                workingText.AppendLine(files[i] + ".jpg");
                workingText.AppendLine(",");
                workingText.AppendLine(files[i+1] + ".jpg");
                workingText.AppendLine(",");

                Console.WriteLine("The image file names of the non working cameras above have been appended to list of nonworking cameras.");
            }

            else
            //images same
            {
                Console.WriteLine("These images below are the same- conclusion CAMERA NOT WORKING ");
                Console.WriteLine(files[i] + ".jpg");
                Console.WriteLine(files[i+1] + ".jpg");


                notWorkingText.AppendLine(files[i] + ".jpg");
                notWorkingText.AppendLine(",");
                notWorkingText.AppendLine(files[i+1] + ".jpg");
                notWorkingText.AppendLine(",");

                Console.WriteLine("The image file names of the non working cameras above have been appended to list of nonworking cameras.");

            }

        }
        // Console.WriteLine(equalElements);


        // you probably shouldn't be using static StreamWriters here 
        using (writetext) 
        {
            writetext.Write(workingText.ToString());
        }    
        using (writetext2) 
        {
            writetext2.Write(notWorkingText.ToString());
        }          

        Console.ReadLine();
