这些都是自动属性

这是另一种写带有支持字段属性的方式。

public class Genre
{
    private string _name;

    public string Name 
    { 
      get => _name;
      set => _name = value;
    }
}

这意味着，如果您创建类型为Genre的变量，您将能够将该变量作为属性访问

Genre oG = new Genre();
oG.Name = "Test";

The get/set pattern provides a structure that allows logic to be added during the setting ('set') or retrieval ('get') of a property instance of an instantiated class, which can be useful when some instantiation logic is required for the property. A property can have a 'get' accessor only, which is done in order to make that property read-only When implementing a get/set pattern, an intermediate variable is used as a container into which a value can be placed and a value extracted. The intermediate variable is usually prefixed with an underscore. this intermediate variable is private in order to ensure that it can only be accessed via its get/set calls. See the answer from Brandon, as his answer demonstrates the most commonly used syntax conventions for implementing get/set.

属性就像一个层，它将私有变量与类的其他成员分开。从外界看来，属性只是一个字段，可以使用.Property访问属性

public class Person
{
    public string FirstName { get; set; }

    public string LastName { get; set; }

    public string FullName => $"{FirstName} {LastName}";
}

public class Person
{
    public string FirstName { get; set; }

    public string LastName { get; set; }

    public string FullName { get { return $"{FirstName} {LastName}"; } }
}

FullName是一个属性。有箭头的那个是捷径。从外部世界，我们可以像这样访问FullName:

var person = new Person();
Console.WriteLine(person.FullName);

调用者并不关心您如何实现FullName。但在类内部，你可以随心所欲地更改FullName。

它是c#的一个自动实现的属性。

在Visual Studio中，如果你在一个类中定义了一个属性X，并且你只想将这个类用作一个类型，在构建项目之后，你会得到一个警告，说“字段X从未被赋值，并且总是有它的默认值”。

通过添加{get;设置;}到X属性，则不会得到此警告。

此外，在Visual Studio 2013及更高版本中，通过添加{get;设置;}你就可以看到对该属性的所有引用。
