Object.GetType Method

July 28, 2014

Gets the Type of the current instance.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public Type GetType()

Return Value

Type: System.Type
The Type instance that represents the exact runtime type of the current instance.

For two objects x and y that have identical runtime types, Object.ReferenceEquals(x.GetType(),y.GetType()) returns true.

The Type object exposes the metadata associated with the class of the current Object.

The following code example demonstrates that GetType returns the runtime type of the current instance.


using System;

public class MyBaseClass : Object
{
}

public class MyDerivedClass : MyBaseClass
{
}

public class Example
{

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      MyBaseClass myBase = new MyBaseClass();
      MyDerivedClass myDerived = new MyDerivedClass();
      object o = myDerived;
      MyBaseClass b = myDerived;

      outputBlock.Text += String.Format("mybase: Type is {0}", myBase.GetType()) + "\n";
      outputBlock.Text += String.Format("myDerived: Type is {0}", myDerived.GetType()) + "\n";
      outputBlock.Text += String.Format("object o = myDerived: Type is {0}", o.GetType()) + "\n";
      outputBlock.Text += String.Format("MyBaseClass b = myDerived: Type is {0}", b.GetType()) + "\n";
   }
}


/*

This code produces the following output.

mybase: Type is MyBaseClass
myDerived: Type is MyDerivedClass
object o = myDerived: Type is MyDerivedClass
MyBaseClass b = myDerived: Type is MyDerivedClass
