Difficult to say with so little information, but a guess is that one of the columns in the variable row is set to null.

Change from

C#

Convert.ToDecimal(row["CimplicityPatientCaseID"])

to

C#

DBNull.Value.Equals(row["CimplicityPatientCaseID"]) ? 0 : Convert.ToDecimal(row["CimplicityPatientCaseID"])

and do the same for the other columns, CaseID and PatActID.

Solution 2

It seems some of column data is null. So in order to avoid use code like below:

C#

x.PatientID == (Convert.IsDBNull(row["CimplicityPatientCaseID"])? 0 : Convert.ToDecimal(row["CimplicityPatientCaseID"]));

Note: Do the same for other two columns CaseID and PatActID
