C# 中类和结构的区别

In order to differentiate between classes and structures, we must first understand that structures and classes appear to be equivalent in the context of holding and defining data. Both can define and save some default values in their data members. However, if we think about them beyond this context, classes provide more flexibility and functionality compared to structures.

The following are the important differences between classes and structures.

Sr. Number	Key	Class	Structure
1	Data type	The data defined in the class is stored in memory as a reference and has a specific address for access, so it can be represented as a class is Reference type.	On the other hand, in case of structure the value of the data member is stored directly on the stack or inline in the containing type, so the structure is treated as a value type.
2	Storage	As mentioned above, in the case of Class, the data members are stored as references, and the reference types are allocated on the heap memory . td>	On the other hand, the value is stored directly in the structure, so the value type is allocated on the stack memory.
3	Constructor	A class can be defined using constructors and destructors as it implements its functionality.	On the other hand, a structure cannot have a constructor or destructor because no such implementation is provided in it.
4	Instantiation	As a class introduced through the constructor, its instances can be instantiated using the new keyword.	On the other hand, structures can create instances without the new keyword.
5	Inheritance	A class can inherit properties from its parent class because it supports inheritance functionality.	On the other hand, structures do not support inheritance.
Protected modifier	We can use the protected modifier for data members defined in the class as Class supports the protected modifier.	Structure on the other hand does not support the protected modifier.
