C # Read the base class implementation of XML files

Just to new units, learning their source code, the code to read and write the system configuration file of the XML code compared to the old, directly written in a system configuration class, no class splitting, causing the class is very large, at the same time, the operation of XML read and write operations are using setattribute and Node.attribute (name) method, therefore, the thought of combining the previous XML operation, completed a can read the XML file base class, easy to use later.

PS: Even if the old code, and currently do not dare to optimize, one is the level not, two is not afraid.

Using static extension classes, several frequently used types are extended to facilitate the reading and writing of data.

The classes that manipulate XML can inherit baselinqxmlfileinfo directly, only need to set the variable mpathname,mfilename of the protected type, and then rewrite the abstract method to implement the read operation of the XML document.

PS: The ability is limited, the wrong place please correct me, thank you.
