在C＃中初始化公共属性的最佳方法是什么？

Question

我需要给属性赋初始值，我想知道是否有比使用构造函数更简单的方法。

Answer 1

Are you using automatically implemented properties? The value type properties will be initialized to their default values. Reference types will be initialized to null.

If you want them to initialize them to some other I think the best option is to set them in the constructor.

If you are not using automatically implemented properties you can initialize them where they are declared.

It will also be useful to keep in mind the order in which the objects fields and constructors are initialized.

Answer 2

If you are taking advantage of automatic properties, the constructor is the easiest way. If you are not, then your member variable can define the default value.

private string _someString = "Hello.";

But, you'll have to define the getter and setter yourself.

public string SomeString
{
    get { return _someString; }
    set { _someString = value; }
}

Which wouldn't be simpler than just defining the default in the constructor.

Answer 3

If you just want to initialize the property values, then constructors are simply enough I don't see why you think they are not simple.

However you can do this if you want, you can initialize the variable like this :

int _myProperty = 5;
public int MyProperty
{
  get{ return _myProperty ;}

 set { _myProperty=value; }
}

Answer 4

I like to think about this a bit differently. If the value is something that is mandatory for the creation of an instance, it needs to be a parameter for the constructor.

However, if the value is optional then setting it via a property is fine.

Answer 5

Well Constructors are best for doing this. How ever u can call a methods too.
