Learn how to handle a WMI property when it does not match the. NET data type.

When the WMI property does not match the. NET data type
When the designers of WMI (Windows Management instrumentation) Create their classes, they do not take into account. NET programmer. You will find that many WMI properties do not directly match the. NET data types. For example, although WMI supports unsigned integer types, vb.net does not support it. Sometimes you can use it. NET provides the structure to imitate. In other cases, you need to turn off Option Strict in vb.net to process WMI data. If you find that your code does not run when Option Strict is opened, you can isolate the "fault" code in a separate module, at the top of the module, and set Option Strict to OFF.

Excluding a class member when serializing an object
When serializing an object, serializer saves all the values associated with your object (even private values) in the output stream. Because. NET serializer is designed to allow you to save and restore the entire state of an object or group of objects, so it is critical that serializer save all data (not just public data). If you want to explicitly exclude any class member when serializing an object, add the Nonserializable property to a specific member. (This technique applies only to the SoapFormatter and BinaryFormatter classes--xmlformatter classes do not save private data, because it is intended to serialize data that can be used for XML WEB services. Where private data is not useful. ）
