Getting all file names from a folder using C#
提问by user2061405
I wanted to know if it is possible to get all the names of text files in a certain folder.
我想知道是否可以获取某个文件夹中文本文件的所有名称。
For example, I have a folder with the name Maps, and I would like to get the names of all the text files in that folder and add it to a list of strings.
例如，我有一个名为 Maps 的文件夹，我想获取该文件夹中所有文本文件的名称并将其添加到字符串列表中。
Is it possible, and if so, how I can achieve this?
是否有可能，如果有，我该如何实现？

I would recommend you google 'Read objects in folder'. You might need to create a reader and a list and let the reader read all the object names in the folder and add them to the list in n loops.
我建议你谷歌“读取文件夹中的对象”。您可能需要创建一个阅读器和一个列表，让阅读器读取文件夹中的所有对象名称，并在 n 次循环中将它们添加到列表中。

Take a look at Directory.GetFiles Method (String, String)(MSDN).
看看Directory.GetFiles 方法（字符串，字符串）（MSDN）。
This method returns all the files as an array of filenames.
此方法将所有文件作为文件名数组返回。

DirectoryInfo d = new DirectoryInfo(@"D:\Test");//Assuming Test is your Folder
FileInfo[] Files = d.GetFiles("*.txt"); //Getting Text files
string str = "";
foreach(FileInfo file in Files )
{
str = str + ", " + file.Name;
}
Hope this will help...
