This article delves into methods for recursively traversing folders and their subfolders in C# to obtain lists of file paths. By analyzing a common issue—how to design a recursive method that returns a list rather than relying on global variables—we explain the core logic of recursive algorithms, memory management considerations, and exception handling strategies. Based on the best answer, we refactor the DirSearch method to independently return file lists, supporting multiple calls with different directories. We also compare simplified approaches using Directory.GetFiles and discuss alternatives to avoid memory blocking, such as iterators. The goal is to provide a structured, reusable, and efficient implementation for directory traversal, applicable to various scenarios requiring dynamic file list retrieval.
