Answer 1

You have 3 versions of "GetFiles" method. 2 of which includes a filter option: https://msdn.microsoft.com/en-us/library/system.io.directory.getfiles%28v=vs.110%29.aspx

The version you were using accepts a "path". Not a filter.

• Option 1 Directory.GetFiles with two arguments:

  var files = Directory.GetFiles(animatedgifsdirectory, "*.gif");
  

• Option 2 DirectoryInfo.GetFiles instance method takes filter as single parameter:

  var directory = new DirectoryInfo(animatedgifsdirectory);
  var files = directory.GetFiles(animatedgifsdirectory, "*.gif");
  

Answer 2

Use the search pattern overload on GetFiles:

System.IO.Directory.GetFiles(@"C:\Windows", "*.gif");
