推荐答案

1）使用Directory.GetFiles [ ^ ]。请参阅： http://www.csharp-examples.net/get-files-from-directory/ [ ^ ]

2）使用 Substring [ ^ ]方法。请参阅： http://www.dotnetperls.com/substring [ ^ ]

1) Use Directory.GetFiles[^]. See: http://www.csharp-examples.net/get-files-from-directory/[^]
2) Use Substring[^] method. See: http://www.dotnetperls.com/substring[^]

应该识别Linq，同时更新你的VS'

确保你已经使用System.Linq写了特定的类;

Linq should be recognized, update your VS'' also:
make sure you have written in that specific class "using System.Linq;"

是substring是获取文件名的最佳方法

yes substring is the best way to get the name of file
