■ Control 클래스를 사용해 컨트롤 이벤트를 제거하는 방법을 보여준다.

▶ 예제 코드 (C#)


using System.ComponentModel;
using System.Reflection;
using System.Windows.Forms;

#region 이벤트 제거하기 - RemoveEvent(targetControl, eventName)

/// <summary>
/// 이벤트 제거하기
/// </summary>
/// <param name="targetControl">타겟 컨트롤</param>
/// <param name="eventName">이벤트명</param>

    PropertyInfo propertyInfo = targetControl.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);

    object fieldValue = fieldInfo.GetValue(targetControl);

    EventHandlerList eventHandlerList = (EventHandlerList)propertyInfo.GetValue(targetControl, null);

    eventHandlerList.RemoveHandler(fieldValue, eventHandlerList[fieldValue]);
