Read all text files in a folder with StreamReader

I am trying to read all .txt files in a folder using stream reader. I have this now and it works fine for one file but I need to read all files in the folder. This is what I have so far. Any suggestions would be greatly appreciated.

using (var reader = new StreamReader(File.OpenRead(@"C:\ftp\inbox\test.txt")))

You can retrieve the files of a directory:

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

Therefore you can iterate each file performing whatever you want. Ex: reading all lines.

And also you can use a file mask as a second argument for the GetFiles method.

Edit:

Inside this post you can see the difference between EnumerateFiles and GetFiles.

What is the difference between Directory.EnumerateFiles vs Directory.GetFiles?

You can use Directory.EnumerateFiles() method instead of.

Returns an enumerable collection of file names that match a search pattern in a specified path.

var txtFiles = Directory.EnumerateFiles(sourceDirectory, "*.txt");
foreach (string currentFile in txtFiles)
{
   ...
}

You can call Directory.EnumerateFiles() to find all files in a folder.
