C# | Object.GetTypeCode() Method with Examples Last Updated : 01 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report This method is used to return the Type of the current instance. Here, Type Represents type declarations i.e. class types, interface types, array types, value types, enumeration types, type parameters, generic type definitions, and open or closed constructed generic types. The System.Object class is the base class for all the types which are present in the .NET Framework type system. Basically, this method returns the Type objects that represent all .NET Framework types. The .NET Framework recognizes the following five categories of types: Classes, which are derived from System.Object. Value types, which are derived from System.ValueType. Interfaces, which are derived from System.Object starting with the .NET Framework 2.0. Enumerations, which are derived from System.Enum. Delegates, which are derived from System.MulticastDelegate. Syntax: public Type GetType (); Return Value: This method returns the run-time type of the current instance. Below programs illustrate the use of Object.GetType() Method: Example 1: CSharp // C# program to demonstrate // Object.GetType() Method using System; // Base class public class G { } // Derived class public class X : G { } // Driver Class class GFG { // Main method public static void Main() { // Creating and initializing objects X obj = new X(); G obj1 = new G(); Object obj2 = obj; // Find the type of objects // using GetType() method Console.WriteLine("The X class object type is: " + obj.GetType()); Console.WriteLine("The G class object type is: " + obj1.GetType()); Console.WriteLine("The obj2 object type is: " + obj2.GetType()); } } Output: The X class object type is: X The G class object type is: G The obj2 object type is: X Example 2: CSharp // C# program to demonstrate // Object.GetType() Method using System; public class Author { public string A_Name; public string P_Name; public int n; public Author(string A_Name, string P_Name, int n) { this.A_Name = A_Name; this.P_Name = P_Name; this.n = n; } public void Show() { Console.WriteLine("Author Name : " + A_Name); Console.WriteLine("Article Name : " + P_Name); Console.WriteLine("Article No : " + n); } public void type() { Console.WriteLine("Type of Author Name : " + A_Name.GetType()); Console.WriteLine("Type of Article Name : " + P_Name.GetType()); Console.WriteLine("Type of Article No : " + n.GetType()); } } // Driver Class class GFG { // Main method public static void Main() { // Creating and initializing // the object of Author class Author obj = new Author("Kirti", "GetType() method", 3); Console.WriteLine("Author details:"); obj.Show(); // Display the type obj.type(); Console.WriteLine("Type of Author class object: " + obj.GetType()); } } Output: Author details: Author Name : Kirti Article Name : GetType() method Article No : 3 Type of Author Name : System.String Type of Article Name : System.String Type of Article No : System.Int32 Type of Author class object: Author Reference: https://docs.microsoft.com/en-us/dotnet/api/system.object.gettype?view=netframework-4.7.2 Comment More infoAdvertise with us K Kirti_Mangal Follow Improve Article Tags : C# CSharp-method CSharp Object Class Similar Reads C# Tutorial C# (pronounced "C-sharp") is a modern, versatile, object-oriented programming language developed by Microsoft in 2000 that runs on the .NET Framework.
