I will get data in DataTable. I am going to iterate data in foreach. I will have all types of data in Datatable. Now I need to find Double for each item (string) in DataTable. How to find IsDouble for string? 
Ex:
I have "21342.2121" string. I need to covert this to Double. But sometimes the data will be "TextString". So I can't use Double.Parse().
How to handle this?
