比较IntPtr / UIntPtr与nint / nuint

基于：

  • I.10.3 ECMA 的运算符重载部分
  • 运算符重载
  • 可重载运算符（C# 编程指南）

转换

除了支持隐式转换之外：

  • IntPtr与nint之间的转换
  • UIntPtr到/从nuint

与IntPtr / UIntPtr的可用转换相比，支持以下转换。

1从纯 C++ 的角度来看，为 CLI 编写这些函数的方式在一个非常重要的方面有所不同。在 C++ 中，这些方法必须直接递增或递减其操作数，而在 CLI 中则不能；相反，它们只是根据需要返回其操作数的值 +/- 1，而不修改其操作数。操作数必须由生成 ++/-- 运算符代码的编译器递增或递减，与对这些方法的调用分开。

2 C++ 中不存在 op_True 和 op_False 运算符。提供它们是为了支持三态布尔类型，例如数据库语言中使用的类型。

二元运算符

下表显示了可以与给定二元运算符的标头中的类型一起使用的类型。默认情况下，这适用于表达式左侧或右侧的类型（二元运算符）。但是，在某些情况下，运算符可能仅可用于表达式特定一侧的类型，其中(R)表示“仅右侧”。
