例

次の例では、対応する型のハンドルを返し、ハンドルから型を取得して表示するメソッドにハンドルを渡します。

using namespace System;
using namespace System::Reflection;
ref class MyClass
{
public:
   int myField;
};

void DisplayTypeHandle( RuntimeTypeHandle myTypeHandle )
{
   
   // Get the type from the handle.
   Type^ myType = Type::GetTypeFromHandle( myTypeHandle );
   
   // Display the type.
   Console::WriteLine( "\nDisplaying the type from the handle:\n" );
   Console::WriteLine( "The type is {0}.", myType );
}

int main()
{
   try
   {
      MyClass^ myClass = gcnew MyClass;
      
      // Get the type of MyClass.
      Type^ myClassType = myClass->GetType();
      
      // Get the runtime handle of MyClass.
      RuntimeTypeHandle myClassHandle = myClassType->TypeHandle;
      DisplayTypeHandle( myClassHandle );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception: {0}", e->Message );
   }

}

using System;
using System.Reflection;
class MyClass
{
    public int myField = 10;
}

class Type_TypeHandle
{
    public static void Main()
    {
        try
        {
            MyClass myClass = new MyClass();

            // Get the type of MyClass.
            Type myClassType = myClass.GetType();

            // Get the runtime handle of MyClass.
            RuntimeTypeHandle myClassHandle = myClassType.TypeHandle;

            DisplayTypeHandle(myClassHandle);
        }
        catch(Exception e)
        {
            Console.WriteLine("Exception: {0}", e.Message );
        }
    }

    public static void DisplayTypeHandle(RuntimeTypeHandle myTypeHandle)
    {
        // Get the type from the handle.
        Type myType = Type.GetTypeFromHandle(myTypeHandle);
        // Display the type.
        Console.WriteLine("\nDisplaying the type from the handle:\n");
        Console.WriteLine("The type is {0}.", myType.ToString());
    }
}

注釈

TypeHandle 型を表す内部データ構造体へのポインターをカプセル化します。 このハンドルは、プロセスの有効期間中に一意です。 ハンドルは、取得されたアプリケーションドメインでのみ有効です。
