c＃中的动态内存管理 [英] dynamic memory manage in c#

问题描述

我想在c＃

i want do like that code in c#

node=(struct student *)new(struct student);

节点是指针，我想做那个工作

node is pointer and i want to do that job

推荐答案

你通常不会在C＃中使用指针 - 你可以，但只能 不安全代码 [ ^ 并且很难做到。



除非你在C＃和外部非.NET代码之间传递数据，否则你需要认真的性能调整它是一个非常好的馊主意。改为使用引用：

You don't normally use pointers in C# - you can, but only in unsafe code[^] and it is deliberatly difficult to do.

Unless you are passing data between C# and external non-.NET code, or you need serious performance tuning it is a very bad idea. use a reference instead:

Student node = new Student();

并让系统为您排序。

using System.Runtime.InteropServices;

node=(student *)Marshal.AllocHGlobal(sizeof(student));

这正是我想要的和它的真实

this is exactly what i want and its true
