短c#代替Java的路径。我的兄弟姐妹。不可能？

Question

我有一个文件路径string filePath = @"C:\MyDir\MySubDir\myfile.ext";和另一个文件名string file2 = "otherfile.txt"。假设我想获得另一个文件路径string filePath2 = @"C:\MyDir\MySubDir\otherfile.txt";

在c#中是否有创建此类文件路径2的方法

在Java中，方法是

Path resolveSibling(Path other)

Resolves the given path against this path's parent path. This is useful where a file name needs to be replaced with another file name. For example, suppose that the name separator is "/" and a path represents "dir1/dir2/foo", then invoking this method with the Path "bar" will result in the Path "dir1/dir2/bar".

Answer 1

类似这样（将第一个文件的目录名和第二个文件名组合在一起）：

  string filePath = @"C:\MyDir\MySubDir\myfile.ext";
  string file2 = "otherfile.txt";

  // C:\MyDir\MySubDir\otherfile.txt
  string result = Path.Combine(Path.GetDirectoryName(filePath), file2);
