List<string> MyKeyWords = GetKeywords();
var allDirectories = new DirectoryInfo("Path").GetDirectories("*", SearchOption.AllDirectories);
lstView.ItemsSource = (from di in allDirectories from fi in di.GetFiles("*.txt") where HasKeyWordMatch(fi, MyKeyWords) select fi);

private bool HasKeyWordMatch(FileInfo fi, List<string> MyKeyWords)
{
try
{
StreamReader testTxt = new StreamReader(fi.FullName);
string allRead = testTxt.ReadToEnd();
testTxt.Close();
string regMatch = "string";
if (Regex.IsMatch(allRead, regMatch))
{
return true;

}
else
{
return false;
}

}
catch (Exception ex)
{
return false;
