code Behing更新web.config文件映射问题 [英] Code Behing update web.config mapping issue

问题描述

我从code后面，我需要更新我的web.config。这从来就不是一个问题之前，但我最近得到一个错误。错误说无法映射路径'/'。
该行注释掉是什么，我尝试了不同的变化。

  //配置myWebConfig = WebConfigurationManager.OpenWebConfiguration（使用Server.Mappath（〜））;
        //配置myWebConfig = WebConfigurationManager.OpenWebConfiguration（〜）;
        //配置myWebConfig = WebConfigurationManager.OpenWebConfiguration（NULL）;
        配置myWebConfig = WebConfigurationManager.OpenWebConfiguration（。）;
        //更新页面的主题
        RoleManagerSection部分=（RoleManagerSection）myWebConfig.GetSection（的System.Web / roleManager）;
        section.DefaultProvider =SqlRoleManager;
        section.Providers.Clear（）;
        ProviderSettings providerSettings =新ProviderSettings（）;
        providerSettings.Name =SqlRoleManager;
        providerSettings.Type =System.Web.Security.SqlRoleProvider;
        providerSettings.Parameters.Clear（）;
        providerSettings.Parameters.Add（的connectionStringName，SimpleTickConnection）;
        providerSettings.Parameters.Add（的applicationName，TheaterSales）;
        section.Providers.Add（providerSettings）;
        myWebConfig.Save（）;
 

解决方案

我想通了错误的原因。从我的本地C移动网站后：驱动器西部数据的护照和运行应用程序启动的错误。 code以下的线路是好的：

 配置myWebConfig = WebConfigurationManager.OpenWebConfiguration（〜/）;
 

I from the code behind I need to update my web.config. This has never been a problem before, however I am getting an error recently. The errors say "Failed to map the path '/'." The lines commented out were different variations of what i tried.

//Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration(Server.MapPath("~"));
        //Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration("~");
        //Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration(null);
        Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration(".");
        // update pages theme
        RoleManagerSection section = (RoleManagerSection)myWebConfig.GetSection("system.web/roleManager");
        section.DefaultProvider = "SqlRoleManager";
        section.Providers.Clear();
        ProviderSettings providerSettings = new ProviderSettings();
        providerSettings.Name = "SqlRoleManager";
        providerSettings.Type = "System.Web.Security.SqlRoleProvider";
        providerSettings.Parameters.Clear();
        providerSettings.Parameters.Add("connectionStringName", "SimpleTickConnection");
        providerSettings.Parameters.Add("applicationName", "TheaterSales");
        section.Providers.Add(providerSettings);
        myWebConfig.Save();

解决方案

I figured out the reason for the error. After moving the site from my local C: drive to a western digital passport and running the app the error started. The line of code below is fine:

Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration("~/");
