c# - System.IO.IOException: file used by another process ...
stackoverflow.com › questions › 1025407System.IO.IOException: The process cannot access the file 'E:\mypath\myFile.cs' because it is being used by another process. at System.IO.__Error.WinIOError (Int32 errorCode, String maybeFullPath) at System.IO.File.Delete (String path) at callingMethod.modifyFile (FileInfo file, String extractedMethod, String modifiedMethod) Normally these errors come from unclosed file streams, but I've taken care of that.
