Проблема изменения Web.Config в SharePoint

Question

У меня есть небольшая проблема здесь в отношении модификации файлов web.config в Feature Штамповка (SP2010 [Web Feature Уровень приложений, Активация по умолчанию])

я столкнулся два странных Вопросы

1. Применяемая модификация типа (добавление дочернего узла) появляется несколько раз в web.config.
2. При отключении функции, я удаляю модификацию против владельца, она получает модификацию, но Они не удаляются.

Я использую следующий снимок кода во время активации функции.

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(); 

Это то, что я делаю при деактивации функции.

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(); 
    } 
}

Answer 2

Этот класс обладает всеми необходимыми атрибутами и содержит значение.

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

Это не проблема, я могу добавить записи конфигурации в файл web.config. Проблемы, как я описал выше.

Answer 3

Поскольку вы не разместили код для CreateModification(), я должен угадать, но я думаю, что там что-то не так.

Важно, что свойство Name SPWebConfigModification имеет значение, соответствующее правилу XPath. Предположим, что это то, что вы пытаетесь:

добавить [ключ = «testadd»]

Это выглядит хорошо, но это не так. Так как «ключ» является атрибутом, как «имя» и другие, это правильный путь:

добавить [@ ключ = «testadd»]

Это вызывает множество записей и делает изменение невозможно удалить ,
