.NET中的类和对象是什么? [英] What is Class and Objects in .NET?

问题描述

大家好，

我无法获得有关DOT NET框架中的类和对象的明确答案.我需要一个实用的答案，请告诉我所有又一件事，引用和对象之间的关系是什么?以下代码行是我对所有这些事情的怀疑.

班级学生
{
//成员和字段
学生st1 =新学生();
}
st1是学生还是学生?如果st1是学生班级的对象，学生班级的参考在哪里?还有一个存储在堆内存中?请告诉我一个切合实际的答案.

谢谢与问候

该对象位于(堆)内存中.您所拥有的只是一个引用，即st1(有了这样的引用，您就可以访问所有对象成员).

The object is in (heap) memory. All you have of it is a reference, namely st1 (with such reference you gain access to all object members).

student是类(即对象的类型).
st1是对该对象的引用.
对象本身(即类实例)位于堆中.
:)

student is the class (i.e. the type of the object).
st1 is a reference to the object.
The object itself (i.e. the class instance) is in the heap.
