How do I search for a list of files using wildcard

Question

How do I use wildcards in C# to list down files contained in a selected folder?

Answer 1

Use DirectoryInfo.GetFiles

using System.IO;

DirectoryInfo folder = new DirectoryInfo(@"C:\foo\bar");
if (folder.Exists) // else: Invalid folder!
{
    FileInfo[] files = folder.GetFiles("*.xml");

    foreach (FileInfo file in files)
    {
        DoSomething(file.FullName);
    }
}
