C # Object-oriented way to set, read application configuration

Focus Point :

• 1. Access and set configuration items in an object-oriented manner (Get,set)
• 2. Workarounds for "callermembername" under. NET 4

The last week, everyone has entered the New Year mode. The body is still, the heart is far away. Recently things are not many, always look at the flash is not right AH. So I remembered a few days ago to see an article: "In. NET, a more convenient way to manipulate configuration items "; so try. As a result of a problem, the article uses the Callermembername property to simplify access to configuration items that require hard-coded key with the configuration item, which is used to tag the property name automatically at run time, but this is more than. NET 4.5. Since we do industrial control needs to be compatible with the old operating system of IPC,. NET has been 4.0. The compatibility issue was met. Baidu came out, found Yang Zhengko Teacher's approach is to use StackTrace specific is: "New StackTrace (true)." GetFrame (1). GetMethod (). Name ". The classes in the article were then modified:

The INotifyPropertyChanged interface is implemented so that the interface refreshes the display when the value of the configuration item changes when the interface binds the configuration item.

Look at this article is not understand, we need to look at the original text.
