　　Here is a very close-up of the mouth need to look carefully:Destory (): shows that a destructor that invokes an object is equivalent to releasing some dynamic memory that an object needs to release to prepare for the next really freed

In C, array arguments behave as though they are passed by reference, and scalar variables and constants are passed by value (like var parameters and value parameters, respectively, in Pascal or modula ).Thus, any changes made by a function to a

Donet provides four equality functions, namely referenceequal, static equal, specific equal, and =. First, object. referenceequal and static equal Public static bool referenceequal (OBJ left, OBJ right) It is worth noting that when the object.

Textreader and textwriter are very useful. Many Methods accept them as parameters. Textreader has two subclasses: Stringreader/stringwriter is used to read strings; Streamreader/streamwriter is used to read streams; I. Role of
