Gets a reference to the Type object for the type that declares this member.
public:
virtual property Type ^ DeclaringType { Type ^ get(); };C#
public override Type? DeclaringType { get; }C#
public override Type DeclaringType { get; }member this.DeclaringType : TypePublic Overrides ReadOnly Property DeclaringType As TypeThe type that declares this member.
A member of a class (or interface) is either declared or inherited from a base class (or interface).
The following code sample illustrates the use of DeclaringType.

// Create assembly in current CurrentDomain
AssemblyName^ myAssemblyName = gcnew AssemblyName;
myAssemblyName->Name = "TempAssembly";
// Create a dynamic assembly
myAssemblyBuilder = myCurrentDomain->DefineDynamicAssembly(
myAssemblyName, AssemblyBuilderAccess::RunAndSave );
// Create a dynamic module in the assembly.
myModuleBuilder = myAssemblyBuilder->DefineDynamicModule( "TempModule" );
FieldInfo^ myFieldInfo =
myModuleBuilder->DefineUninitializedData( "myField", 2, FieldAttributes::Public );
// Create a type in the module
TypeBuilder^ myTypeBuilder = myModuleBuilder->DefineType( "TempClass", TypeAttributes::Public );
FieldBuilder^ myGreetingField = myTypeBuilder->DefineField( "Greeting",
String::typeid, FieldAttributes::Public );
array<Type^>^myConstructorArgs = {String::typeid};
// Define a constructor of the dynamic class.
ConstructorBuilder^ myConstructor = myTypeBuilder->DefineConstructor(
MethodAttributes::Public, CallingConventions::Standard, myConstructorArgs );

// Add declarative security to the constructor.
Console::WriteLine( "Adding declarative security to the constructor....." );
Console::WriteLine( "The Security action to be taken is \"DENY\" and" +
" Permission set is \"UNRESTRICTED\"." );
myConstructor->AddDeclarativeSecurity( SecurityAction::Deny, myPset );

Type^ myAttributeType = MethodAttributes::typeid;
int myAttribValue = (int)myMethodAttributes;
if ( !myAttributeType->IsEnum )
{
Console::WriteLine( "This is not an Enum" );
}
array<FieldInfo^>^myFieldInfo1 = myAttributeType->GetFields( static_cast<BindingFlags>(BindingFlags::Public | BindingFlags::Static) );
