数组中的新关键字 [英] key word new in array

问题描述

大家好，

有什么区别 int []x=new int[]{1,2,3};
和
int[]x={1,2,3};

Thnx提供任何帮助

Hi everyone,
What a difference between
int []x=new int[]{1,2,3};
and
int[]x={1,2,3};

Thnx for any help

推荐答案

在.Net中，不同的代码语法生成相同的代码.

考虑下面的两位代码:

In .Net different code syntax produces identical code.

Consider the two bits of code below:

private string myString;

public string MyString
{
  get
  {
    return myString;
  }

  set
  {
    myString = value;
  }
}

和

and

public string MyString {get; set;}

他们俩都做完全一样的事情

第二个块基本上只是创建第一个块的简便方法.

对于第二个Array示例，C#编译器知道"您要创建一个新的int[]并在后台为您完成.

这只是使编码人员的工作更轻松的最新方法.

They both do exactly the same thing

The second block is basically just a shorthand way to create the first.

For your second Array example the C# compiler ''knows'' that you want to create a new int[] and does it for you behind the scenes.

It is just a more recent way to do it to make the coders job easier.

据我所知，没有什么区别.

它们只是声明和实例化数组的两种不同方式.我怀疑在幕后产生的IL代码会是相同的.

As far as I know, there is no difference.

They are just two different ways to declare and instantiate Arrays. I suspect that behind the scenes the IL code produced would be the same.
