问题更改Web.config文件的SharePoint

我有一个关于在功能冲压web.config文件中修改一个小问题在这里（SP2010 [Web应用程序级别功能，激活缺省]）问题更改Web.config文件的SharePoint

我面临两个怪问题

像（添加子节点）应用的修改在web.config中出现多次。
在功能停用时，我将删除对所有者的修改，它获得修改，但是这些不会被删除。

我在功能激活过程中使用了下面的代码片段。

ModificationEntry[] enries = 
{ 
    new ModificationEntry("someName", "someSection", SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode) 
}; 

    SPWebApplication WebApp = (SPWebApplication)properties.Feature.Parent; 
WebApp.WebConfigModifications.Clear(); 

foreach (ModificationEntry entry in enries) 
{ 
    // CreateModification simply return me SPWebConfigModification 
    SPWebConfigModification configModificationItem = CreateModification(entry, properties.Feature.DefinitionId.ToString()); 
    if (!WebApp.WebConfigModifications.Contains(configModificationItem)) 
    { 
     WebApp.WebConfigModifications.Add(configModificationItem); 
    } 
} 

WebApp.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications(); 
WebApp.Update();

这就是我正在做的功能停用。

if (webApp != null) 
{ 
    Collection<SPWebConfigModification> collection = webApp.WebConfigModifications; 
    int iStartCount = collection.Count; 

    // Remove any modifications that were originally created by the owner. 
    for (int c = iStartCount - 1; c >= 0; c--) 
    { 
     SPWebConfigModification configMod = collection[c]; 
     if (configMod.Owner == properties.Feature.DefinitionId.ToString()) 
      collection.Remove(configMod); 
    } 

    // Apply changes only if any items were removed. 
    if (iStartCount > collection.Count) 
    { 
     webApp.Update(); 
     webApp.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications(); 
    } 
}

请评论！

其中是ModificationEntry/CreateModification的代码。你似乎没有一个'路径'变量在任何地方（除非是someSection），但那么'价值' – djeeg 2011-02-03 22:18:16

该类具有所有必需的属性，它也包含Value。

ModificationEntry("someName", "someSection", “Value”, SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode)

这不是问题，我可以将配置项添加到web.config文件。问题如上所述。

由于您没有发布CreateModification（）的代码，我必须猜测它，但我认为那里有些问题。

SPWebConfigModification的Name属性值是正确的XPath非常重要。假如这是你想要什么：

添加[键=“testadd”]

这看上去很好，但事实并非如此。由于“钥匙”是一个属性，比如“名”和其他人，这是正确的做法：

添加[@键=“testadd”]

这导致多个条目，使修改无法删除。
