c#: getter/setter | 易学教程

问题

I saw something like the following somewhere, and was wondering what it meant. I know they are getters and setters, but want to know why the string Type is defined like this. Thanks for helping me.

public string Type { get; set; }

回答1:

Those are Auto-Implemented Properties (Auto Properties for short).

The compiler will auto-generate the equivalent of the following simple implementation:

private string _type;

public string Type
{
    get { return _type; }
    set { _type = value; }
}

回答2:

That is an auto-property and it is the shorthand notation for this:

private string type;
public string Type
{
  get { return this.type; }
  set { this.type = value; }
}

回答3:

In C# 6:

It is now possible to declare the auto-properties just as a field:

public string FirstName { get; set; } = "Ropert";

Read-Only Auto-Properties

public string FirstName { get;} = "Ropert";

回答4:

public string Type { get; set; }

Is no different then doing

private string _Type;

public string Type
{    
get { return _Type; }
set { _Type = value; }
}

回答5:

This means that the compiler defines a backing field at runtime. This is the syntax for auto implemented properties.

回答6:

Its a automatically backed property, basically equivalent to

private string type;
public string Type
{
   get{ return type; }
   set{ type = value; }
}

回答7:

These are called auto properties.

Functionally (and in terms of the compiled IL), they are the same as properties with backing fields.

回答8:

I know this is an old question but with the release of C# 6, you can now do something like this for private properties.

public constructor()
{
   myProp = "some value";
}

public string myProp { get; }
