Solution 1

You're using exclamation marks (!!, ASCII code 33) instead of vertical bars (||, ASCII code 124):

C#

DateTime dt = new DateTime(1900, 1, 1);
if (rowLB.IsNull("CloseDate") || Convert.ToDateTime(rowLB["CloseDate"]) == dt)
{
    ...
}

Instead of using exclamation mark use || operator and Use the Datetime compare methods to get the actual results.
for example, || dt.CompareTo(Convert.ToDateTime(closedate))==0)

If compareTo method returns the values based on,

Less than zero - This instance is earlier than value.

Zero - This instance is the same as value.

Greater than zero - This instance is later than value, or value is null.
