Switch over PropertyType

        System.Type propertyType = typeof(Boolean);
        System.TypeCode typeCode = Type.GetTypeCode(propertyType);
        switch (typeCode)
        {
            case TypeCode.Boolean:
                //doStuff
                break;
            case TypeCode.String:
                //doOtherStuff
                break;
            default: break;
        }

You can use an hybrid approach for TypeCode.Object where you dynamic if with typeof. This is very fast because for the first part – the switch – the compiler can decide based on a lookup table.
