Update datetime field by blank in datatable

      DataTable dtModetare = oCatalogcl.Moderate();
      dtModetare.Rows[0]["dt_moderate"] = DBNull.Value;
      DataTable dt = dtModetare;

Verbatim String

A verbatim string is one that does not need to be escaped, like a filename:

string myFileName = "C:\\myfolder\\myfile.txt";

would be

string myFileName = @"C:\myfolder\myfile.txt";

The @ symbol means to read that string literally, and don't interpret control characters otherwise.
