推荐答案

这很容易给它的通过重定向到自己在ASP.NET初始状态重新设置的页面。这里有3种方式可以做到这一点：

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. 的Response.Redirect（Request的）;

在该路径请求以下形式psented $ P $：/MyApp/MyFile.aspx

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

1. 的Response.Redirect（Request.RawUrl）;

在这不仅是露出的路径，但也可以是任何查询字符串参数，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. 的Response.Redirect（Request.Url.ToString（））;

在这不仅是路径和查询字符串参数曝光，但作为形式的绝对基准可用：
要播/ MyApp的/ MyFile.aspx？富=栏

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
