C# GetType MethodUnderstand the result of the GetType method. GetType returns a Type object.
GetType. This is a C# method on object. It provides a Type object. This object indicates the most derived type of the object instance.
Type
Object
Returned value. GetType in .NET accesses the actual type of the object instance. It does not report the base types or the variable type.
Example program. This program uses the GetType method on a base type reference to more derived objects. We instantiate 3 classes—A, B and C—in Main.
Class
New
Constructor
Info The class A is used as base class. The class B derives from class A. And the class C derives from class B.
Base
Main This executes and creates an instance of each class, but stores the references in the A type variables.
Next The GetType method returns the most derived type of the instances, not the type of the variable.
using System; class A { } class B : A { } class C : B { } class Program { static void Main() { A a1 = new A(); A a2 = new B(); A a3 = new C(); Console.WriteLine(a1.GetType()); Console.WriteLine(a2.GetType()); Console.WriteLine(a3.GetType()); } }
A B C
A summary. We demonstrated the GetType method when used with derived and base classes. This C# method returns the most-derived class—it does not return base classes.
