推荐答案

在Page_InitComplete中，我的理解是ViewState 实际上并没有您要操纵的地方.与其像这样操作ViewState，不如改写SaveViewState 方法，最好是这样:

In Page_InitComplete, my understanding is that the ViewState is not actually there for you to manipulate. Rather than manipulate the ViewState like this, you would be better overriding the SaveViewState method like this:

protected override object SaveViewState()
{
  object[] vs = new object[2];
  vs[0] = base.SaveViewState(); // This gets the original viewstate
  vs[1] = _somethingToSave;

  return vs;
}
