我在这里有一个关于修改特征标记中的Web.Config文件的问题（SP2010 [Web应用程序级别功能，默认激活]）
我面临两个奇怪的问题
我在功能激活期间使用了以下代码片段。
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();
这就是我在功能停用时所做的事情。
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！

答案 1 :(得分：1)
由于你没有发布CreateModification（）的代码，我不得不猜测它，但我觉得有些问题。
对于SPWebConfigModification的Name属性，重要的是值是正确的XPath。假设这是你正在尝试的：
添加[key ='testadd']
这看起来很好，但事实并非如此。由于'key'是一个属性，比如'name'和其他属性，这是正确的方法：
添加[@ key ='testadd']
这会导致多个条目，并且无法删除修改。
答案 2 :(得分：0)
此类具有所有必需属性，并且还包含值。
ModificationEntry("someName", "someSection", “Value”, SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode)
这不是问题，我可以在web.config文件中添加配置条目。问题如上所述。
