function GetType ( ) : 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.
[ C#, JScript ] The following code example demonstrates that GetType returns the runtime type of the current instance.
[ C# ]
using System;
public class MyBaseClass: Object {
}
public class MyDerivedClass: MyBaseClass {
}
public class Test {
public static void Main ( ) {
MyBaseClass myBase = new MyBaseClass ( );
MyDerivedClass myDerived = new MyDerivedClass ( );
object o = myDerived;
MyBaseClass b = myDerived;
Response.Write ( "mybase: Type is {0}", myBase.GetType ( ) );
Response.Write ( "myDerived: Type is {0}", myDerived.GetType ( ) );
Response.Write ( "object o = myDerived: Type is {0}", o.GetType ( ) );
Response.Write ( "MyBaseClass b = myDerived: Type is {0}", b.GetType ( ) );
}
}
