推荐答案

在 ASP.NET 中，通过重定向到自身，可以轻松地将页面重置为其初始状态.这里有 3 种方法可以做到:

It's easy to reset a page to it's initial state in ASP.NET by redirecting to itself. Here are 3 ways you can do it:

1. Response.Redirect(Request.Path);

其中请求的路径以下列形式呈现:/MyApp/MyFile.aspx

In which the path to the request is presented in the following form: /MyApp/MyFile.aspx

1. Response.Redirect(Request.RawUrl);

其中不仅公开了路径，还公开了任何查询字符串参数，例如:/MyApp/MyFile.aspx?foo=bar

In which not only is the path exposed, but also any querystring parameters like: /MyApp/MyFile.aspx?foo=bar

1. Response.Redirect(Request.Url.ToString());

其中不仅公开了路径和查询字符串参数，而且还提供了以下形式的绝对引用:MyServer/MyApp/MyFile.aspx?foo=bar

In which not only is the path and querystring parameters exposed, but made available as an absolute reference in the form: MyServer/MyApp/MyFile.aspx?foo=bar
