How to check if a file exists in a folder?

Question

I need to check if an xml file exists in the folder.

DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles(\"*.xml\");         


        

Answer 1

This is a way to see if any XML-files exists in that folder, yes.

To check for specific files use File.Exists(path), which will return a boolean indicating wheter the file at path exists.

Answer 2

This helped me:

bool fileExists = (System.IO.File.Exists(filePath) ? true : false);

Answer 3

Since nobody said how to check if the file exists AND get the current folder the executable is in (Working Directory):

if (File.Exists(Directory.GetCurrentDirectory() + @"\YourFile.txt")) {
                //do stuff
}

The @"\YourFile.txt" is not case sensitive, that means stuff like @"\YoUrFiLe.txt" and @"\YourFile.TXT" or @"\yOuRfILE.tXt" is interpreted the same.
