推荐答案

1.在报告页面中，要返回的位置请使用anchors ，如下例所示;
< h2><名称="1">您的第一份报告</a></h2>
...
< h2><名称="2">您的第二个报告</a></h2>
...
2.然后，当您启动报告时，您还应该发送(或缓存)参数作为锚名称，例如，如果您启动第二个报告，您还应发送(或缓存)值"2".
3.最后，通过使用上面的参数，通过在URL的末尾添加一个#2"，最后使用返回的参数来构建您的后退按钮URL.

1.In your reports page use anchors in places where you want to come back, like in the next example;
<h2><a name="1">Your 1st Report</a></h2>
...
<h2><a name="2">Your 2nd report</a></h2>
...
2.Then when you start a report your should send (or cache) as parameter also the anchor name, for example if you start the 2nd report you should send (or cahce) also the value "2".
3.Finally build your URL for back button by using also the param from point above by adding a "#2" at the end of the URL in the case of example from point 2 above.

全局声明
静态字符串prevPageUrl = String.Empty;
将其写在page_load事件中
prevPageUrl = Request.UrlReferrer.ToString();

在btn_click()
中 Response.Redirect(prevPageUrl);

引用此链接，您还可以了解获得以前的url的多少方法

Response.Redirect(prevPageUrl);
