Now that we have understood the concept of Stack and Heap, it's time to understand the concept of value types and reference types.
It stops you from putting null into ordinary reference types such as string- it makes those types non-nullable!
它阻止你null进入普通的引用类型，例如string-它使这些类型不可为空！它是温和的，有警告，而不是错误。!In fact, all reference types have a lifetime, but most of the time you do not have to write it explicitly.
实际上，所有的引用类型都有一个生命周期，但在大多数时候你无需将它显式写出来。Note that type parameters can represent only reference types not primitive types(like int, double and char).
注意类型参数只能代表引用型类型，不能是原始类型（像int,double,char的等）.Furthermore, C supports both user-defined reference types and value types, allowing dynamic allocation of objects as well as in-line storage of lightweight structures.
此外，C同时支持用户定义的引用类型和值类型，既允许对象的动态分配，也允许轻量结构的内联存储。Microsoft has made available Nullable Reference Types as preview for developers who want to try the new feature and provide feedback.
微软已经为开发者提供了预览版的可空引用类型（NullableReferenceType），想尝鲜的开发者可以尝试这个新特性，并提供反馈。Both reference types specifically model direct causal relationships between a child Span and a parent Span.
这两种引用类型代表了子节点和父节点间的直接因果关系。Reference types inherit directly from Object, while all value types inherit directly from a type called ValueType, which in turn inherits from Object.
Referencetype直接继承自object；所有valuetype则直接继承自valueType,后者又继承自object。The primary difference is that structs are value types and classes are reference types.
就是，主要一个区别就是：struct是值类型的，而class是引用类型的。Blueprint variables can also be reference types for holding things like Objects, Actors, and Classes.
蓝图变量也可以是保存对象、Actor和类等资源的引用类型。About a year ago I wrote a post Introducing Nullable Reference Types in C.
大约一年前，我写了一篇介绍C中的可空引用类型的文章。C has 15 predefined types, 13 value types, and 2(string and object) reference types.
C有15个预定义类型，其中13个是值类型，两个是引用类型(string和object).Chapter 5 covers all of the details regarding JavaScript's built-in reference types such as object and array.
第5章“引用类型”，详尽介绍了JavaScript内置的所有引用类型，如Object和Array。Unlike value types, reference types are not copied when they are assigned to a variable or constant, or when they are passed to a function.
不同于值类型，引用类型，在被赋值到一个变量或常量时，或者当它们被传递给一个函数时，其不会被复制。Developers can define new value types through enum and struct declarations, and can define new reference types via class, interface, and delegate declarations.
开发人员可以通过枚举声明和结构声明定义新的值类型，并可通过类声明、接口声明和委托声明定义新的引用类型。Value of Reference type can be only in two cases.
引用类型的值只有可能是以下两种情况：.Since every reference type represents an underlying.
由于每种引用类型表示基础.If T is reference type, nothing is done.
若T是引用类型，则不做任何事。ParamType is a pointer or reference type, but not a universal 1 reference. .
类型说明符是指针或者引用类型，但不是universalreference.The target type must be a pointer or reference type, and the expression being cast must evaluate to a pointer or reference. .
目标类型必须是指针或引用类型，并且表达式必须计算为指针或引用。
