Question

我似乎无法在FeatureRecievers Activated事件中找到我对web.config所做的修改。我尝试在停用事件中从SpWebApplication.WebConfigModifications集合中获取修改，但这始终是空的....最奇怪的是，在停用该功能后，我的更改仍然会被恢复...

我的问题是，在Deactivating事件中访问SpWebApplication.WebConfigModifications集合时，我是否应该无法查看对web.config文件所做的所有更改？我应该如何明确删除我的更改？


 public class FeatureReciever : SPFeatureReceiver
{
    private const string FEATURE_NAME = "HelloWorld";
    private class Modification
    {
        public string Name;
        public string XPath; 
        public string Value; 
        public SPWebConfigModification.SPWebConfigModificationType ModificationType;
        public bool createOnly;

    public Modification(string name, string xPath, string value, SPWebConfigModification.SPWebConfigModificationType modificationType, bool createOnly)
    {
        Name = name;
        XPath = xPath;
        Value = value;
        ModificationType = modificationType;
        this.createOnly = createOnly;
    }
}

private Modification[] modifications =
{ 
    new Modification("connectionStrings", "configuration", "<connectionStrings/>", SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode, true),
    new Modification("add[@name='ConnectionString'][@connectionString='Data Source=serverName;Initial Catalog=DBName;User Id=UserId;Password=Pass']", "configuration/connectionStrings", "<add name='ConnectionString' connectionString='Data Source=serverName;Initial Catalog=DBName;User Id=UserId;Password=Pass'/>", SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode, false)
};

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    SPSite siteCollection = (properties.Feature.Parent as SPWeb).Site as SPSite;
    SPWebApplication webApplication =  siteCollection.WebApplication;
    siteCollection.RootWeb.Title = "Set from activating code at " + DateTime.Now.ToString();

    foreach (Modification entry in modifications)
    {
        SPWebConfigModification webConfigModification = CreateModification(entry);
        webApplication.WebConfigModifications.Add(webConfigModification);
    }
    webApplication.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications();
    webApplication.WebService.Update();
}

public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
    SPSite siteCollection = (properties.Feature.Parent as SPWeb).Site as SPSite;
    SPWebApplication webApplication = siteCollection.WebApplication;
    siteCollection.RootWeb.Title = "Set from deactivating code at " + DateTime.Now.ToString();

    IList<SPWebConfigModification> modifications = webApplication.WebConfigModifications;
    foreach (SPWebConfigModification modification in modifications)
    {
        if (modification.Owner == FEATURE_NAME)
        {
            webApplication.WebConfigModifications.Remove(modification);
        }
    }

    webApplication.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications();
    webApplication.WebService.Update();
}

public override void FeatureInstalled(SPFeatureReceiverProperties properties)
{
}

public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
{
}

private SPWebConfigModification CreateModification(Modification entry)
{
    SPWebConfigModification spWebConfigModification = new SPWebConfigModification()
    {
        Name = entry.Name,
        Path = entry.XPath,
        Owner = FEATURE_NAME,
        Sequence = 0,
        Type = entry.ModificationType,
        Value = entry.Value
    };

    return spWebConfigModification;
}

}

感谢您的时间。 /汉斯

最后今天我弄清楚我的代码出了什么问题（这就是为什么当我在停用事件中查询它时WebConfigModifications集合为空）似乎你必须以不同于我的方式应用更改。

我应用更改的原始方法涉及以下代码：

激活事件

webApplication.Farm.Services.GetValue().ApplyWebConfigModifications();
webApplication.WebService.Update();

“正确”的做法是这样的：

SPWebService.ContentService.ApplyWebConfigModifications();
webApplication.Update();

虽然我仍然不知道为什么我的原始代码不能正常工作..在Sharepoint中有更多知识配置对象的人可以启发我吗？
