Nulls and Datetime

Jul 18 2022 1:56 PM


I have a small app that loads data from an excel worksheet to a sql server database table via a data table.

I have a column in the spreadsheet that contains a date.

I set the column in the data table thus...

            dt.Columns.Add("EffectiveDateOfTransaction_CR0057", typeof(DateTime));

and on processing each row of the spreadsheet into the data table thus...

            MyNewRow["EffectiveDateOfTransaction_CR0057"] = (DateTime)(worksheet.Cells[i, 25] as Excel.Range).Value;

I get an exception as DateTime cannot be null.

I have checked the web, but I am pretty new to this, there seems to be something DateTime?, but I cant seem to make it work.

Any help appreciated.
