What are base type?
The base type is the type from which the current type directly inherits. Object is the only type that does not have a base type, therefore null is returned as the base type of Object.

What is the object type in C#?
The Object Type is the ultimate base class for all data types in C# Common Type System (CTS). Object is an alias for System. Object class. The object types can be assigned values of any other types, value types, reference types, predefined or user-defined types.
What are the 3 types of bases?
In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases, and Lewis bases.
Is the base class of exception?
Throwable is the base class of all exception and error classes in Java.
Is used to design the base class?
Which class is used to design the base class? Explanation: Abstract class is used to design base class because functions of abstract class can be overridden in derived class hence derived class from same base class can have common method with different implementation, hence forcing encapsulation.
Is type in C#?
The is operator is used to check if the run-time type of an object is compatible with the given type or not. It returns true if the given object is of the same type otherwise, return false. It also returns false for null objects. Here, the expression will be evaluated to an instance of some type.
How do I know what type of object?
You can check object type in Java by using the instanceof keyword. Determining object type is important if you’re processing a collection such as an array that contains more than one type of object. For example, you might have an array with string and integer representations of numbers.
What is an example of the basetype property?
The Type from which the current Type directly inherits, or null if the current Type represents the Object class or an interface. The following example demonstrates using the BaseType property. The following example uses recursion to list the complete inheritance hierarchy of each class found in an assembly.
How does the type.basetype property return null?
Interfaces inherit from zero or more base interfaces; therefore, this property returns null if the Type object represents an interface. The base interfaces can be determined with GetInterfaces or FindInterfaces.
Which is the base type of a class?
The example defines a class named C that derives from a class named B, which, in turn, derives from a class named A. The base type is the type from which the current type directly inherits.
When to use basetype vs.class in Java?
If the current Type represents a type parameter of a generic type definition, BaseType returns the class constraint, that is, the class the type parameter must inherit. If there is no class constraint, BaseType returns System.Object.
