2019-8-30-C#-反射调用私有事件

class A
{
private event EventHandler Fx
{
add { }
remove { }
}
}

var eventInfo = typeof(A).GetEvent("Fx", BindingFlags.Instance | BindingFlags.NonPublic);

var eventInfo = typeof(A).GetEvent("Fx", BindingFlags.Instance | BindingFlags.NonPublic); var a = new A(); eventInfo.AddEventHandler(a, new EventHandler(Fx)); void Fx(object sender, EventArgs e)
{
}

System.InvalidOperationException:“由于不存在此事件的公共添加方法，因此无法添加该事件处理程序。”

var eventInfo = typeof(A).GetEvent("Fx", BindingFlags.Instance | BindingFlags.NonPublic);
var addFx = eventInfo.GetAddMethod(true);
var removeFx = eventInfo.GetRemoveMethod(true); var a = new A(); addFx.Invoke(a, new[] {new EventHandler(Fx)});
removeFx.Invoke(a, new[] {new EventHandler(Fx)}); void Fx(object sender, EventArgs e)
{
}
