如何将更改后的值写回web.config
本文关键字:写回 web config | 更新日期: 2023-09-27 18:18:19
在我的网页。配置文件,我有下面的部分,
<system.webServer>
<rewrite>
<rules>
<rule name="rule 1D" stopProcessing="true">
<match url="^(.*)$" />
<!--<action type="Rewrite" url="//offline.html" />-->
</rule>
</rules>
</rewrite>
</system.webServer>
现在我需要更改stopProcessing的值并将其写回web.config。这是我到目前为止所做的
using System;
using System.IO;
using System.Linq;
using System.Web.UI;
using System.Xml.Linq;
namespace WebApplication3
{
public partial class About : Page
{
protected void btn1_Click(object sender, EventArgs e)
{
var configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
var section = configuration.GetSection("system.webServer");
var xdoc = XDocument.Load(new StringReader(section.SectionInformation.GetRawXml()));
var dec = xdoc.Descendants("system.webServer");
var stopProcessing = dec.Descendants("rules").SelectMany(i => i.Elements()).Select(s1 => s1.Attribute("stopProcessing")).Single().Value;
stopProcessing = "false";
configuration.Save();
}
}
}
但是改变没有反映....
我在做什么错误?
完成 web . config

重要提示:改变网络。配置文件通常会导致应用程序重新启动。
如果你的应用程序需要灵活的设置,那么你应该考虑另一种方法…比如使用路由或自定义httphandler,从XML文件或DB中读取/写入数据。
下面是一些可能在处理配置文件时会派上用场的东西:
WebConfigurationManager.OpenWebConfiguration(HttpRuntime.AppDomainAppVirtualPath);
// "WebConfigurationManager" is located in the "System.Web.Configuration" namespace.
