使用 SharePoint 2010 我正在尝试使用 SPWebConfigModification 类对场中的应用程序上的 web.config 文件进行一些基本更改，包括使用 Web 应用程序范围功能的管理中心 web.config 文件，其中功能接收器处理添加/删除修改：

public override void FeatureActivated(SPFeatureReceiverProperties properties)
    {
        SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;
        String ownerId = properties.Feature.DefinitionId.ToString();
        List<SPWebConfigModification> modsToAdd = new List<SPWebConfigModification>();

        #region Authentication Providers

        modsToAdd.Add(new SPWebConfigModification()
        {
            Name = "defaultProvider",
            Owner = ownerId,
            Path = "configuration/system.web/membership",
            Sequence = 0,
            Type = SPWebConfigModification.SPWebConfigModificationType.EnsureAttribute,
            Value = "FBA_AD_MP"
        });

        modsToAdd.Add(new SPWebConfigModification()
        {
            Name = "add [@name=\"FBA_AD_MP\"] [@type=\"System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a\"] [@connectionStringName=\"ADFBAConnectionString\"] [@enableSearchMethods=\"true\"] [@attributeMapUsername=\"userPrincipalName\"]",
            Owner = ownerId,
            Path = "configuration/system.web/membership/providers",
            Sequence = 0,
            Type = SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode,
            Value = "<add name=\"FBA_AD_MP\" type=\"System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a\" connectionStringName=\"ADFBAConnectionString\" enableSearchMethods=\"true\" attributeMapUsername=\"userPrincipalName\" />"
        });

        #endregion

        #region Connection Strings

        modsToAdd.Add(new SPWebConfigModification()
        {
            Name = "connectionStrings",
            Owner = ownerId,
            Path = "configuration",
            Sequence = 0,
            Type = SPWebConfigModification.SPWebConfigModificationType.EnsureSection,
            Value = "<connectionStrings />"
        });

        modsToAdd.Add(WebConfigModificationsUtility.CreateConnectionStringModification(ownerId, 1, "ADFBAConnectionString", properties.Feature.Properties["ADFBAConnectionString"].Value));

        #endregion

        WebConfigModificationsUtility.AddWebConfigModifications(webApp, modsToAdd.ToArray());
    }

WebConfigModificationsUtility 类是这些功能接收器共享的简单实用程序：

public static void AddWebConfigModifications(SPWebApplication webApp, params SPWebConfigModification[] modificationsToAdd)
    {
        AddWebConfigModifications(webApp, true, modificationsToAdd);
    }
public static void AddWebConfigModifications(SPWebApplication webApp, Boolean persistChanges, params SPWebConfigModification[] modificationsToAdd)
    {
        foreach (SPWebConfigModification curMod in modificationsToAdd)
        {
            SPWebService.ContentService.WebApplications[webApp.Id].WebConfigModifications.Add(curMod);                
        }

        if (persistChanges)
        {
            PersistWebConfigModifications(webApp);
        }
    }
public static void PersistWebConfigModifications(SPWebApplication webApp)
    {
        SPWebService.ContentService.WebApplications[webApp.Id].Update();                        
        SPWebService.ContentService.ApplyWebConfigModifications();
    }

在内容应用程序上一切正常，但在尝试激活中央管理 Web 应用程序上的功能时，SPWebConfigModificaiton 项目永远不会写入 web.config 文件。我已经验证代码正在执行，没有异常。此外，我的功能接收器尝试删除任何修改是在停用时进行的：

public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;
            String ownerId = properties.Feature.DefinitionId.ToString();
            WebConfigModificationsUtility.RemoveWebConfigModifications(webApp, ownerId);
        }
public static void RemoveWebConfigModifications(SPWebApplication webApp, String ownerId, Boolean persistChanges)
        {            
            RemoveWebConfigModifications(webApp, persistChanges, webApp.WebConfigModifications.Where(x => x.Owner == ownerId).ToArray());
        }
public static void RemoveWebConfigModifications(SPWebApplication webApp, Boolean persistChanges, params SPWebConfigModification[] modificationsToRemove)
        {
            foreach (SPWebConfigModification curMod in modificationsToRemove)
            {
                SPWebService.ContentService.WebApplications[webApp.Id].WebConfigModifications.Remove(curMod);                
            }

            if (persistChanges)
            {
                PersistWebConfigModifications(webApp);
            }
        }

当此代码在 Central Admin Web 应用程序上运行时，它会找到在功能激活中创建的四个修改并成功删除它们，但这些操作实际上都没有更改 Web 应用程序的 web.config 文件；它甚至没有被触及，上次编辑日期的时间戳始终保持不变。

我发现各种博客都在谈论 SPWebConfigModification 类的继承技巧，大多数问题都在正确使用 Name 和 Owner 属性，以及使用 SPWebService 静态属性正确持久化更改，但尽我所能告诉我正在关注所有推荐的做法。我开始怀疑 API 中存在错误，但我想知道是否有人在 SharePoint 2010 中成功完成了此操作，或者我是否应该打开 Reflector 并尝试查看提供了什么？

Just like ContentService, SPWebService has an AdministrationService object which also has a WebApplications collection. Use the AdministrationService to get to your CentralAdmin web applications.
