【C#属性】C＃Properites没有存储位置。 C＃属性是字段的扩展，并且像字段一样进行访问。
这些属性具有用于设置，获取或计算其值的访问器。
C＃属性的用法
- C＃属性可以是只读或只写的。
- 在C＃属性中设置值时，我们可以拥有逻辑。
- 我们将类的字段设为私有，这样就不能直接从类外部访问字段。现在我们被迫使用C＃属性来设置或获取值。
using System;
public class Employee
{
private string name;
public string Name
{
get
{
return name;
}
set
{
name = value;
}
}
}
class TestEmployee{
public static void Main(string[] args)
{
Employee e1 = new Employee();
e1.Name = "Sonoo Jaiswal";
Console.WriteLine("Employee Name: " + e1.Name);
}
}输出：
Employee Name: Sonoo JaiswalC＃属性示例2：在设置值时具有逻辑
using System;
public class Employee
{
private string name;
public string Name
{
get
{
return name;
}
set
{
name = value+" srcmini";
}
}
}
class TestEmployee{
public static void Main(string[] args)
{
Employee e1 = new Employee();
e1.Name = "Sonoo";
Console.WriteLine("Employee Name: " + e1.Name);
}
}输出：
Employee Name: Sonoo srcminiC＃属性示例3：只读属性
using System;
public class Employee
{
private static int counter;
public Employee()
{
counter++;
}
public static int Counter
{
get
{
return counter;
}
}
}
class TestEmployee{
public static void Main(string[] args)
{
Employee e1 = new Employee();
Employee e2 = new Employee();
Employee e3 = new Employee();
//e1.Counter = 10;
//Compile Time Error: Can't set valueConsole.WriteLine("No. of Employees: " + Employee.Counter);
}
}输出：
No. of Employees: 3
