Type.IsInstanceOfType Method
.NET Framework 4.5
Determines whether the specified object is an instance of the current Type.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- o
- Type: System.Object
The object to compare with the current type.
Return Value
Type: System.Booleantrue if the current Type is in the inheritance hierarchy of the object represented by o, or if the current Type is an interface that o supports. false if neither of these conditions is the case, or if o is null, or if the current Type is an open generic type (that is, ContainsGenericParameters returns true).
Implements
_Type.IsInstanceOfType(Object)
NoteThe following example demonstrates the use of the IsInstanceOfType method.
using System; public interface IMyIfc {} public class MyClass : IMyIfc {} public class MyDerivedClass : MyClass {} class IsInstanceTest { public static void Main() { Type imyifcType=typeof(IMyIfc); MyClass mc = new MyClass(); Type mcType = mc.GetType(); MyClass mdc = new MyDerivedClass(); Type mdcType = mdc.GetType(); int [] array = new int [10]; Type arrayType = typeof(Array); Console.WriteLine("Is int[] an instance of the Array class? {0}.", arrayType.IsInstanceOfType(array)); Console.WriteLine("Is myclass an instance of MyClass? {0}.", mcType.IsInstanceOfType(mc)); Console.WriteLine("Is myderivedclass an instance of MyClass? {0}.", mcType.IsInstanceOfType(mdc)); Console.WriteLine("Is myclass an instance of IMyIfc? {0}.", imyifcType.IsInstanceOfType(mc)); Console.WriteLine("Is myderivedclass an instance of IMyIfc? {0}.", imyifcType.IsInstanceOfType(mdc)); } }
