我有一个路径，我需要确定它是否是一个目录或文件。

I have a path and I need to determine if it is a directory or file.

这是确定的路径是一个文件的最好方法？

Is this the best way to determine if the path is a file?

string file = @"C:Testfoo.txt";

bool isFile = !System.IO.Directory.Exists(file) && 
                         System.IO.File.Exists(file);

有关目录我会扭转的逻辑。

For a directory I would reverse the logic.

string directory = @"C:Test";

bool isDirectory = System.IO.Directory.Exists(directory) && 
                            !System.IO.File.Exists(directory);

如果两者都不存在的话，我不会去做任何分支。因此，假设他们都这样做存在。

If both don't exists that then I won't go do either branch. So assume they both do exists.

推荐答案

使用：

System.IO.File.GetAttributes(string path)

和检查FileAttributes 结果返回是否包含值 FileAttributes.Directory ：

and check whether the returned FileAttributes result contains the value FileAttributes.Directory:

bool isDir = (File.GetAttributes(path) & FileAttributes.Directory)
                 == FileAttributes.Directory;
