什么是C＃项目设置&QUOT的实际功能;允许不安全的代码" [英] What is the actual function of the C# project setting "Allow unsafe code"

问题描述

我想知道如果C＃项目设置允许不安全的代码只适用于不安全的C＃代码项目本身，还是有必要设置一个本地C ++ DLL链接时，这个选项？怎么样在自身链接到本机DLL托管DLL链接？这是什么选项真的这么做了，引擎盖下？

I was wondering if the C# project setting "Allow unsafe code" applies only to unsafe C# code in the project itself, or is it necessary to set this option when linking in a native C++ DLL? What about linking in a managed DLL that itself links to a native DLL? What does this option really do, under the hood?

推荐答案

它与C＃中的不安全的关键字做。 不安全关闭所有，通常会发生，使您可以直接访问内存中的检查。它并不是指调用本地C ++ DLL的或接口。

It has to do with the "unsafe" keyword in C#. "unsafe" turns off all the checks that would normally happen and allow you to directly access the memory. it doesn't refer to calling native C++ DLL's or interfaces.
