推荐答案

通过使用

By using

Directory.GetDirectoryRoot(path)

DirectoryInfo info = Directory.GetParent(path);

这两行将得到上面想要的所有结果.

these two lines you will get all the results what you want above.

var path = "C:\Program Files\Test1\Test2\Test3\Test4";

var pathItems = path.Split('\');

var paths = new List<string>();

for(var i = 0; i < pathItems.Length; i++)
{
    var items = pathItems.Skip(0).Take(i+1).ToArray();

    paths.Add(string.Join(@"\", items);
}

然后，以下路径包含在变量"paths"中.

1.C:\
2.C:\ Program Files \
3.C:\ Program Files \ Test1 \
4.C:\ Program Files \ Test1 \ Test2 \
5.C:\ Program Files \ Test1 \ Test2 \ Test3 \
6.C:\ Program Files \ Test1 \ Test2 \ Test3 \ Test4

The following paths are then contained in the variable "paths".

1.C:\
2.C:\Program Files\
3.C:\Program Files\Test1\
4.C:\Program Files\Test1\Test2\
5.C:\Program Files\Test1\Test2\Test3\
6.C:\Program Files\Test1\Test2\Test3\Test4

您真的是这个意思吗

Do you really mean this

public void mysplit(string path)
{
  string[] sa = path.Split(new char[]{'\\'});

  for (int i=0; i < sa.Length; i++)
  {
    string s = (i+1) + "." + sa[0];
    for (int j=1; j<=i; j++)
    {
      s += "\\" + sa[j];
    }
    Console.WriteLine(s);
  }
}
