Retrieving a DateTime value from a DataRow (C#)

Question

How can I get DateTime value in C# from row, the current code is giving me error any help is appreciated, the data is coming in from progress database:

Answer 1

This is just a guess but if the corresponding type in the database is DateTime, could you check if the column is nullable?

If so you may want to do a check r["column"] == DBNull.Value and then pass it to a nullable DateTime? Field.

Or even easier:

row.Field<DateTime?>("column")

If it isn't then yeah, Convert.ToDateTime() or something else should do it.

EDIT:

I see your final code there but is there any chance you want to do this:

DateTime? firstIssueDate = r.Field<DateTime?>("fiss"); 
DateTime? endIssueDate = r.Field<DateTime?>("eiss"); 

if (firstIssueDate.HasValue && endIssueDate.HasValue) 
{ 
    firstIssueDate.Value // blah blah 
    endIssueDate.Value // blah blah 
}

Answer 2

I would recommend using DateTime.Parse() if the row is returning a string for that index.

 string prodCode = r["PRD-CDE"].ToString(),statCode = r["STAT"].ToString();
 DateTime firstIssueDate = DateTime.Parse(r["FISS"].ToString());
 DateTime endIssueDate = DateTime.Parse(r["EISS"].ToString());

You could also use TryParse depending on your needs.
