Just wondering if anyone knows how to fix this error? I\'ve also used TypeCode. but still no luck. Thanks
case typeof(Nullable).ToString
The type you use in the switch statement has to match the type in the case statements, where currently you're comparing a TypeCode to a string.
The TypeCode enumeration only contains values for the primitive types, and all others will be TypeCode.Object. So you can't get a specific TypeCode for the Nullable type.
