Passing dynamic object to C# method changes return type
WebIf the compiler allows us to create the object for an abstract class, we can invoke the abstract method using that object which cannot be executed by CLR at runtime. Hence to restrict calling abstract methods, the compiler does not allow us to instantiate an abstract class. Now, let us implement the two abstract methods inside the child class. WebWhen you pass a dynamic object as a parameter to a method, the C# compiler cannot determine the actual type of the object until runtime. As a result, the return type of the method can change based on the type of the dynamic object. For example, consider the following method that takes a dynamic object as a parameter: consumer industry in us 2023
