Question

我有以下代码，它应该获取当前配置文件，向其中添加一个条目然后写回文件。但是，由于文件被锁定，这不起作用（请参阅堆栈跟踪）。有没有办法在这之前释放它？或者我可以用不同的方式做到这一点吗？

代码：

System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal); // Add an Application Setting.

config.AppSettings.Settings.Add("InputDirectory" + inputdirs.Count + 1, newinputdir);
config.AppSettings.Settings.Add("OutputDirectory" + outputdirs.Count + 1, newoutputdir);

// Save the changes in App.config file.
try
{
    config.Save(ConfigurationSaveMode.Modified);
}
catch (Exception e)
{
    Console.WriteLine(e);
}
Console.WriteLine("Config update successful.");
readConfig();

错误：

he configuration section handler for appSettings. ---> System.InvalidOperationEx
ception: ConfigurationSection properties cannot be edited when locked.

我还尝试使用以下方法手动修改exe配置：

System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoaming); // Add an Application Setting.
XmlDocument doc = new XmlDocument();
doc.Load(@config.FilePath);

然而，这会产生一个问题，因为它似乎不存在。

＆＃39; System.IO.DirectoryNotFoundException＆＃39;发生在System.Xml.dll

中

更新：

我现在正在使用以下内容：

ConfigurationSection settings = config.GetSection("EmailParserWinService.Settings");
settings.SectionInformation.AllowExeDefinition = ConfigurationAllowExeDefinition.MachineToLocalUser;
config.Sections.Add("GENERAL_USER_SETTINGS", settings);
config.Save();

但它在某种程度上是一个空引用。具体来说，这一行： settings.SectionInformation.AllowExeDefinition = ConfigurationAllowExeDefinition.MachineToLocalUser;

不知怎的，我的设置变量（即使我在上面定义了它？）回来了。我认为问题在于我没有提取正确的代码部分。其中哪一部分包含设置？

    [0] "system.data.dataset"   object {string}

写入锁定的设置文件？
