C#_ Basics _ Partial class partial (18)

Under the same namespace, you can define only one class of the same class name, for example, there can be only one person class under a namespace.

Partial classes: Understanding that each part is just part of the constituent class, is actually a class, all members are shared, that is, variables defined in a partial class,

In another part of the class can be used, then the variables defined in a partial class, in other parts of the class can not be repeated definition, it is understood to put a class of members, separate into different classes.

Through the case demonstration:

1 usingSystem;2 usingSystem.Collections.Generic;3 usingSystem.Linq;4 usingSystem.Text;5 usingSystem.Threading.Tasks;6 7 namespacePartial Classes8 {9     class ProgramTen     { One         Static voidMain (string[] args) A         { -  -             // the  -  -         } -     } +  -  +     //only one person class can be defined under a namespace, and the Person class section class may be written A     //Partial : A class is made up of some classes, all of which are common and are actually a class at      Public Partial class Person -     { -         Private stringname; -  -         //void Test ()//will be an error, in another part of the class has -         //{ in  -         //} to     } +  -      Public Partial class Person the     { *         //all members are shared, including private members $        //private string name;Panax Notoginseng  -         voidTest () the         { +             //members of other parts of the class can be directly used A Console.WriteLine (name); the         } +     } -      $      Public Partial class Person $     { -        //You can define multiple partial classes -     } the  - Wuyi}
