Question

让我们考虑一下，

E:/Folder2/Fol24/Fo2222
E:/Folder3/Fol23/Folder333
E:/Folder4/Folde25/Fold44
E:/Folder5/Folder55/Folde5

我需要使用E:/Folder?/Fol2?/Fo*之类的输入来存档并从通配符匹配文件夹中删除所有文件在这里，我期待文件夹E:/Folder2/Fol24/Fo2222和E:/Folder3/Fol23/Folder333

这里的问题是用户可以输入任何通配符的模式。根据模式，我必须将文件复制到其他位置并删除文件。在这里，我无法使用任何固定的搜索模式。它应该是动态的，并且可以包含任意数量的通配符。

感谢您的帮助。

    private static List<string> folders = new List<string>();

    private void buttonExample_Click(object sender, EventArgs e)
    {
        folders.Clear();

        string input = textBox1.Text;
        string currentDir = string.Empty, currentPattern = string.Empty, nextPattern = string.Empty;

        foreach (char c in input)
        {
            if (c == '?')
            {

                string[] f = input.Split(new[] {'?'}, 2);
                if (f[0].Length > 0)
                {
                    currentDir = Directory.GetParent(f[0]).FullName;
                }

                if (f[1].Length > 0)
                {
                    nextPattern = f[1].TrimStart('\\');
                }

                string[] w = input.Split('\\');
                foreach (string s in w)
                {
                    if (s.Contains('?'))
                    {
                        currentPattern = s;
                        break;
                    }
                }

                break;
            }
            else if(c == '*')
            {
                string[] f = input.Split(new[] { '*' }, 2);

                if (f[0].Length > 0)
                {
                    currentDir = Directory.GetParent(f[0]).FullName;
                }
                if (f[1].Length > 0)
                {
                    nextPattern = f[1].TrimStart('\\');
                }

                string[] w = input.Split('\\');
                foreach (string s in w)
                {
                    if (s.Contains('*'))
                    {
                        currentPattern = s;
                        break;
                    }
                }

                break;
            }
        }
        DirectoryInfo di = new DirectoryInfo(currentDir);
        List<string> foldersNew = new List<string>();
        foldersNew = GetAllFolders(di, currentPattern, nextPattern);
    }

    private static List<string> GetAllFolders(DirectoryInfo currentDir,string currentPattern, string nextPatten)
    {
        DirectoryInfo[] dis = currentDir.GetDirectories(currentPattern);
        if (dis.Length == 0 && string.Equals(currentPattern,string.Empty))
            folders.Add(currentDir.FullName);

        if (dis.Length > 0)
        {
            string[] remainPattern = nextPatten.Split("\\".ToCharArray());
            if (remainPattern.Length > 0)
            {
                foreach (DirectoryInfo di in dis)
                {
                    GetAllFolders(di, remainPattern.First(),
                                   string.Join("\\", remainPattern.Skip(1).ToArray()));
                }
            }

        }

        return folders;
    }

我的解决方案可能对有需要的人有所帮助。这将解决问题。感谢大家的帮助。
