C# Question

Deleting multiple files with wildcard

You know that in linux it's easy but I can't just understand how to do it in C# on Windows. I want to delete all files matching the wildcard

f*.txt
. How do I go about going that?

Answer

You can use the DirectoryInfo.EnumerateFiles function:

var dir = new DirectoryInfo(directoryPath);

foreach (var file in dir.EnumerateFiles("f*.txt")) {
    file.Delete();
}

(Of course, you'll probably want to add error handling.)
