Directory.GetFiles: how to get only filename, not full path?

如何使用 c# 仅获取目录中的文件名？
Using C#, I want to get the list of files in a folder.
My goal: ["file1.txt", "file2.txt"]
使用 C#，我想获取文件夹中的文件列表。
我的目标：["file1.txt", "file2.txt"]
So I wrote this:
所以我写了这个：
string[] files = Directory.GetFiles(dir);
Unfortunately, I get this output: ["C:\\dir\\file1.txt", "C:\\dir\\file2.txt"]
不幸的是，我得到了这个输出： ["C:\\dir\\file1.txt", "C:\\dir\\file2.txt"]
I could strip the unwanted "C:\dir\" part afterward, but is there a more elegant solution?
之后我可以去掉不需要的 "C:\dir\" 部分，但是有更优雅的解决方案吗？

You can use System.IO.Path.GetFileNameto do this.
您可以使用它System.IO.Path.GetFileName来执行此操作。
E.g.,
例如，
string[] files = Directory.GetFiles(dir);
foreach(string file in files)
Console.WriteLine(Path.GetFileName(file));
While you could use FileInfo, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFilesunless you need the additional functionality of the FileInfoclass.
虽然您可以使用FileInfo，但它比您已经使用的方法（仅检索文件路径）要重量级得多。所以我建议你坚持使用，GetFiles除非你需要这个FileInfo类的附加功能。

Have a look at using FileInfo.Name Property
看看使用FileInfo.Name 属性
something like
就像是
string[] files = Directory.GetFiles(dir);
for (int iFile = 0; iFile < files.Length; iFile++)
string fn = new FileInfo(files[iFile]).Name;
Also have a look at using DirectoryInfo Classand FileInfo Class
也看看 using DirectoryInfo Class和FileInfo Class

Use this to obtain only the filename.
使用它仅获取文件名。
Path.GetFileName(files[0]);
