对象初始化器性能 [英] Object initializer performance

问题描述

在C＃3.0中对象初始化快于常规的方法是什么？

这是更快

  Object对象=新对象
{
    的id = 1;
}
 

比这个？

  Object对象=新的对象（）

object.id = 1;
 

解决方案

在发行模式下，它们将编译到的确切的相同IL code（假设你实际上是使用类型与 ID 属性，而不是对象）

因此​​，将不根据定义没有性能差异。

我不知道哪一个会编得更快，但它会在编译时间分差，你可能不关心，

不过，对象初始化语法中快（少打字），所以你应该使用它。

Is the object initializer in c# 3.0 faster then the regular way?

Is this faster

Object object = new Object
{
    id = 1;
}

than this ?

Object object = new Object()

object.id = 1;

解决方案

In Release mode, they will compile to the exact same IL code (assuming that you're actually using a type with an id property instead of Object)

Therefore, there will by definition be no performance difference.

I don't know which one will compile faster, but it would be a minute difference in compilation time and you probably don't care,

However, the object initializer syntax is written faster (less typing), so you should probably use it.
