C#_ basic Structure struct (eight)

In general, the use of structs is not recommended.

The structure can contain many different types of fields, methods

Define a structure:

1   Public struct Person2         {3              Public string_name;//The naming convention field is underlined before4             Public   int_age;5             Public   Char_gender;6             PublicQqstate _state;//Enum Type7}

struct declaration: Calling

1  // declares a struct variable, essentially the same as an enumeration, where int is a variable, 2 Person              Zhangsan; 3              " Zhangsan " ; 4               - ; 5              Zhangsan._state = qqstate.busy; 6              ' male ';

The structure can also have methods:

1   Public struct Person2         {3              Public string_name;//The naming convention field is underlined before4             Public   int_age;5             Public   Char_gender;6             PublicQqstate _state;//Enum Type7              Public voidRun ()8            {9Console.WriteLine ("Run");Ten}

Call:

Zhangsan. Run ();

Structural Features:

Structs and classes are different and cannot be new objects. Declaring objects directly can

Structure is a value type, so the object is only in the stack and does not open space in the heap

struct does not have a default constructor.

Structure Construction Method: You must assign values to all the fields in the structure to

1  /// <summary>2         ///case with no fields3         /// </summary>4          Public structStudent5         {6              PublicStudent ()7             {8 9             }Ten              Public voidStudy () One             { A  -             } -}

Structure New object:

Student s = new Student ();

1  /// <summary>2         ///structure with Fields3         /// </summary>4          Public struct Person5         {6              Public string_name;//The naming convention field is underlined before7              Public int_age;8              Public Char_gender;9              PublicQqstate _state;//Enum TypeTen            One              PublicPerson (stringname) A             { -                  This. _name =name; -                  This. _age = A; the                  This. _gender ='male'; -                  This. _state =qqstate.busy; -  -             } +  -              +}
