锁定时无法编辑 ConfigurationSection 属性
ConfigurationSection properties cannot be edited when locked
我以为我昨天解决了这个问题，我通过改变我的操作顺序让它工作了。
- 创建新部分
- 向部分添加元素
- 将部分添加到配置
- config.Save()
但是今天我在调用 config.Save()
时再次遇到同样的错误
我最初认为问题可能是因为我在 section 元素本身添加了一个 属性（添加了一个索引 属性），但我反对了。
我的问题是为什么该部分被锁定？什么操作导致部分被锁定。我需要做什么来清除锁定？更新部分的正确顺序是什么？
我应该只保存整个配置一次吗？我正在尝试在修改每个单独的部分后进行保存。
好的，这是我的代码的一部分。除了从 ConfigurationSection 和 ConfigurationElement 派生的 FolderSection 和 FolderElement。这
第一次调用 UpdateFolders() 按预期工作。第二次调用在调用 config.Save() 时失败，内部异常 "ConfigurationSection properties cannot be edited when locked" 我应该在两次调用之间做什么？

我至少可以在测试用例中解决这个问题，如果我将保存从更新中提升 class 所以它只执行一次。
[TestMethod]

UpdateFolders(userConfig, "srcFolders", 0, @"C:\Temp", @"C:\Users\Angela", @"C:\Users\Angela\MyDocuments");
userconfig.Save();
}
重新打开配置似乎也适用于测试用例，但我可以发誓这就是我在原始代码中所做的。
