在C#中创建文件夹时添加数字后缀

Question

如果要创建的文件夹已经存在，我正在尝试处理。要在文件夹名称中添加数字，请执行以下操作。就像windows资源管理器..例如(新建文件夹、新建文件夹1、新建文件夹2 ..)我怎么才能递归呢?我知道这段代码是错误的。我如何修复或者修改下面的代码来解决这个问题？

    int i = 0;
    private void NewFolder(string path)
    {
        string name = "\\New Folder";
        if (Directory.Exists(path + name))
        {
            i++;
            NewFolder(path + name +" "+ i);
        }
        Directory.CreateDirectory(path + name);
    }

Answer 1

为此，您不需要递归，而是应该寻找迭代解决方案

private void NewFolder(string path) {
  string name = @"\New Folder";
  string current = name;
  int i = 0;
  while (Directory.Exists(Path.Combine(path, current)) {
    i++;
    current = String.Format("{0} {1}", name, i);
  }
  Directory.CreateDirectory(Path.Combine(path, current));
}

Answer 2

    private void NewFolder(string path) 
    {
        string name = @"\New Folder";
        string current = name;
        int i = 0;
        while (Directory.Exists(path + current))
        {
            i++;
            current = String.Format("{0} {1}", name, i);
        }
        Directory.CreateDirectory(path + current);
    }

最简单的方法是：

        public static void ebfFolderCreate(Object s1)
        {
          DirectoryInfo di = new DirectoryInfo(s1.ToString());
          if (di.Parent != null && !di.Exists)
          {
              ebfFolderCreate(di.Parent.FullName);
          }

          if (!di.Exists)
          {
              di.Create();
              di.Refresh();
          }
        }
