Need help capturing {} in a dataTable's DataRow.

[Guest]

I'm getting the following Errors during run time and I tried capturing it
using the code below but I'm not able to. I'm also showing in Debug the
value is {}. How can I catch this so it won't create Exception error?
Thanks.

Unable to cast object of type 'System.DBNull' to type 'System.String'.

if ((dr["Primary Group"] != null) && (dr["Primary Group"] != ""))
groupName = (string)dr["Primary Group"];

p- dr["Primary Group"] {} object {System.DBNull}
- Static members
Value {} System.DBNull

p- dr["Primary Group"] {} object {System.DBNull}
- Static members
Value {} System.DBNull

if ((dr["Primary Group"] != null) needs to be:

if ((dr["Primary Group"] != DBNull.Value)

Lookup DbNull.Value in the documentation.

Good luck with your project,

Thank you Otis. I tried System.DBNull before but that didn't work because I
didn't use .Value since I add it, it's now working. Thank you for your help.
