Answer 1

c# version of @qfactor77's answer. This is the best way without LINQ .

string[] wildcards= {"*.mp4", "*.jpg"};
ReadOnlyCollection filePathCollection = FileSystem.GetFiles(dirPath, Microsoft.VisualBasic.FileIO.SearchOption.SearchAllSubDirectories, wildcards);
string[] filePath=new string[filePathCollection.Count];
filePathCollection.CopyTo(filePath,0);

now return filePath string array. In the beginning you need

using Microsoft.VisualBasic.FileIO;
using System.Collections.ObjectModel;

also you need to add reference to Microsoft.VisualBasic
