Consider the following code:

DerivedClass drbObj = (DerivedClass)obj;

Here obj is of type Object and this is reasonable since Object is the base type of every Class in C#.

Here, since the type of derObj is defined at compile time, what is the need to explicitly use type conversion here. Can't the compiler predict on it's own that it will be of DerivedClass. I understand that, the Conversion type doesn't have to match the Derived type, but for practical purpose, it will only be as useful as the Derived type.

Could someone explain with a small, hypothetical example, as to why the Explicit Type Conversion is necessary when a reference of type Object is being assigned to a derived class.

From what I know, in C, there is no need to do perform Explicit type conversion from void* to any pointer and the compiler can handle it, based on the type of the pointer to which the converted value is being assigned.
