如何在 ASPX 中设置控件状态

Question

当我在代码项目中遇到一篇文章时，我正在尝试研究控制状态

http://www.codeproject.com/Articles/331981/A-Beginner-s-Tutorial-Understanding-ControlState-i

但是在该示例中，只有"文本"值保持控制状态，如果我必须同时保留它们怎么办？所以我尝试了这段代码

    protected override void OnInit(EventArgs e)
    {
        Page.RegisterRequiresControlState(this);
        base.OnInit(e);
    }
    protected override object SaveControlState()
    {
        object[] state = new object[2]; // save the 2 properties
        state[0] = Text;
        state[1] = Text1;
        return state;
    }
    protected override void LoadControlState(object savedState)
    {
        object[] state = (object[])savedState;
        Text = (string)state[0];
        Text1 = (string)state[1];
    }

但它似乎不起作用..谁能帮我解决???

提前致谢

您可以使用字典或列表而不是数组

protected override object SaveControlState()
{
    var state = new List<string>(); // save the 2 properties
    state.Add(Text);
    state.Add(Text1);
    return state;
}
protected override void LoadControlState(object savedState)
{
    var state = (List<string>)savedState;
    Text = state[0];
    Text1 = state[1];
}
