1. System.Object The runtime requires every type to ultimately be derived from the System.Object type. Because all types are ultimately derived from System.Object, you are guaranteed that every object of every type has a minimum set of
1.All Types Are Derived from System.Object The CLR requires all objects to be created using the new operator(Employee e = new Employee("ConstructorParam1");) the new operator does: 1.It calculates the number of bytes required 2.It allocates memo
方法: public virtual bool IsAssignableFrom ( Type c ) 1.如果 c 和当前 Type 表示同一类型2.当前 Type 在 c 的继承层次结构中3.当前 Type 是 c 实现的接口44.或者 c 是泛型类型参数且当前 Type 表示 c 的约束之一,则为 true.如果上述情况都不符合,或者 c 为 空引用(在 Visual Basic 中为 Nothing),则为 false. 示例: class Program { static void M
When working with conditionals types, within the “extends” expression, we can use the “infer” keyword to either get the type of the elements of an array, or even to get the return type of a function. We can use this to build a “FnReturnType” type, th
