需要Object引用/不能从引用调用Request

Question

我目前正在尝试创建一个新的Umbraco文档，然后请求查询字符串Rid并运行我的代码（这将找到页面的ID并正确显示）但我不能在它是asp.net用户控件时调用引用请求。我收到错误非静态字段，方法或属性需要对象引用＆＃34; System.Web.Ui.UserControl.Request.get＆＃34;

错误来自（请求未被识别）

 Document rDoc = new Document(Convert.ToInt32(Request.QueryString["rid"]));

有什么想法吗？代码如下。如果您有任何改进，您可以想到/为什么这段代码不起作用的原因，非常感谢解释，谢谢。
