C#中避免不必要装箱与拆箱的方法

Methods of Avoiding Unnecessary Boxing and Unboxing in C#

装箱/拆箱操作是C#中较重要的操作,如果使用不当,开发出来的系统性能将受到较大影响.在具体分析了装箱/拆箱的原理后,通过对实际代码进行性能分析和MSIL反编译程序查看.exe程序的内部机理,提出了通过重载函数、接口方式和泛型来避免不必要的装箱/拆箱;对正在使用C#进行系统开发的人员将有一定的参考价值.

Boxing/unboxing is a more important operation in C#. If it is improperly used in the system design process, the system performance will be greatly impacted. After analysing the principle of boxing/unboxing, the thesis proposes the miss of unnecessary boxing/unboxing by overloaded function, interface mode and generic by way of the code performance analysis and observing executable program＇ s structure by MSIL. This will have reference values for users of c#.
