推荐答案

为文件夹中的所有文本文件制作循环，并使用阅读器读取每个文件，并将您的数据（例如：玫瑰）与读取数据进行比较。

Make loop for all text files in a folder and read each file using reader and compare your data(Ex:Rose) with read data.

您需要的是 Path.GetFileName方法 [ ^ ]

what you need is Path.GetFileName Method[^]

string fileName = @"C:\mydir\myfile.ext";
string result = Path.GetFileName(fileName);//returns 'myfile.ext'
