Store multiple variables of the same type in an array data structure in C#. Declare an array by specifying a type or specify Object to store any type.
The C++ type system consists of the following types: fundamental types(see alsostd::is_fundamental): the typevoid(see alsostd::is_void); the typestd::nullptr_t(see alsostd::is_null_pointer); (since C++11) arithmetic types (see alsostd::is_arithmetic): ...
TypeRangeSize.NET type charU+0000 to U+FFFF16 bitSystem.Char The default value of thechartype is\0, that is, U+0000. Thechartype supportscomparison,equality,increment, anddecrementoperators. Moreover, forcharoperands,arithmeticandbitwise logicaloperators perform an operation on the corresponding cha...
type, if you need to support the three-valued logic, for example, when you work with databases that support a three-valued Boolean type. For the bool? operands, the predefined & and | operators support the three-valued logic. For more information, see the Nullable Boolean logical operators ...
type[] arrayName; 数组是引用类型,因此数组可以是可为 null 的引用类型。 元素类型可能是引用类型,因此可以声明数组来保存可为 null 的引用类型。 以下示例声明显示了用于声明数组或元素可为 null 性的不同语法: C#复制 type?[] arrayName;// non nullable array of nullable element types.type[]? arrayName...

A partial type is a type declaration that allows you to split the declaration of the type into multiple files.
可空引用类型 Null Reference Type 所以,C# 8的可空引用类型就出现了。 C# 8可以让你在编译时就避免null引用错误,它并不是把null值从代码里移除了,而是它可以让你表达意图。具体的做法就是你可以告诉编译器哪个引用可能是null的,而哪些引用不可能是null。
