| Path.GetFullPath(B).StartsWith(Path.GetFullPath(...

Question

Try this:

if (Path.GetFullPath(A).StartsWith(Path.GetFullPath(B)) ||
    Path.GetFullPath(B).StartsWith(Path.GetFullPath(A)))
   { /* ... do your magic ... */ }

is not a , it's a .So you can try this:

If you are not looking for a direct parent-child relationship you can try:

I needed to know if folder B was the same as OR was contained within folder A.

The following worked for me:

Answer 1

我已经尝试过用:

if (!Path.GetFullPath(A).TrimEnd(Path.DirectorySeparatorChar).Equals(Path.GetFullPath(B).TrimEnd(Path.DirectorySeparatorChar), StringComparison.CurrentCultureIgnoreCase)
    && (Path.GetFullPath(A).StartsWith(Path.GetFullPath(B) + Path.DirectorySeparatorChar, StringComparison.CurrentCultureIgnoreCase)
    || Path.GetFullPath(B).StartsWith(Path.GetFullPath(A) + Path.DirectorySeparatorChar, StringComparison.CurrentCultureIgnoreCase)))
   { /* ... do your magic ... */ }

像在

Answer 2

C:\files 后期File但这是行不通的。例如，如果我写 "C:\files "和 "C:\files baaa"，代码认为 "C:\files baaa "是 "C:\files "的子代，但它不是，它只是C:.当我尝试使用长路径，有大量子代时，问题真的很严重。Directory我也试过用 "if contains \"...但还是不能在所有的路径中工作。

DirectoryInfo A = new DirectoryInfo(Path.GetFullPath("firstPath"));
DirectoryInfo B = new DirectoryInfo(Path.GetFullPath("secondPath"));

if( B.Parent.FullName == A.FullName || A.Parent.FullName == B.FullName )

我可以做什么？

if (Directory
    .GetDirectories(A.FullName,"*",SearchOption.AllDirectories)
    .Contains(B.FullName) ||

     Directory
    .GetDirectories(B.FullName, "*", SearchOption.AllDirectories)
    .Contains(A.FullName))

谢谢！我想确定一个路径是否是另一个路径的子路径。
