One, C # as operatorThe as operator is used to perform an explicit type conversion of a reference type. Please read the C # data type.The as operator can be represented in the following format:expression as type?expression: expressions of reference

Some object-oriented languages allow a class to inherit from multiple base classes, while other object-oriented languages allow inheritance from only one class, but can be arbitrarily inherited from several interfaces or pure abstract classes.Only C

First, C # unchecked operatorThe unchecked operator is used to suppress overflow checking of integer arithmetic operations and conversions.Second, promptBy default, these are the unchecked options. Therefore, you need to explicitly use the unchecked

One, C # is operatorThe IS operator is used to check whether an object is compatible with a given type (compatible means that the object is that type, or is derived from that type).The IS operator is used to check whether an object (variable)
