Type::IsInstanceOfType Method
Determines whether the specified object is an instance of the current Type.
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 nullptr, or if the current Type is an open generic type (that is, ContainsGenericParameters returns true).
Implements
_Type::IsInstanceOfType(Object)The following example demonstrates the use of the IsInstanceOfType method.
using namespace System; interface class IMyIfc{}; public ref class MyClass: public IMyIfc{}; public ref class MyDerivedClass: public MyClass{}; int main() { Type^ imyifcType = IMyIfc::typeid; MyClass^ mc = gcnew MyClass; Type^ mcType = mc->GetType(); MyClass^ mdc = gcnew MyDerivedClass; Type^ mdcType = mdc->GetType(); array<Int32>^arr = gcnew array<Int32>(10); Type^ arrayType = Array::typeid; Console::WriteLine( "Is Int32[] an instance of the Array class? {0}.", arrayType->IsInstanceOfType( arr ) ); 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 ) ); }
