C# file exists by file name pattern

Question

Using C# .net v2.

I am using File.Exists(filepath).

What I would like to do is swop this out for a pattern, because the first part of the filename changes...

For example.. the file could be

01_peach.xml
02_peach.xml
03_peach.xml

How can I check if the file exists based on some kind of search pattern?

Answer 1

You can do a direcoty list to check for files

string[] files = Directory.GetFiles(path, "*_peach.xml",SearchOption.TopDirectoryOnly);
if (files.Length > 0)
{
    //file exist
}

Answer 2

Get a list of all matching files using System.IO.DirectoryInfo.GetFiles()
