Question

I have following foreach-loop:

using System.IO; //...    if (Directory.Exists(path)) {     foreach(string strFile in Directory.GetFiles(path, '*.txt'))     {         // do something, possibly delete the file named strFile     } } 

Could there be side effects when deleting files in the directory that is currently used for the foreach-loop?

Answer 1

GetFiles returns an array, not an iterator so the operation is complete by the time you reference the first file. Also it only returns the file names, not a File handle so you should be completely safe doing any operation on it.
