e.g 1: with default format

string StartSearchDate = "30112015"; //30th Nov 2015 

var startSearchDate = StartSearchDate.ToSafeParseExact();


e.g 2: with explicitly passing date format

string StartSearchDate = "11302015"; //30th Nov 2015 
var startSearchDate = StartSearchDate.ToSafeParseExact(), "MM/dd/yyyy");
