ConfigurationManager.save（）失败 [英] ConfigurationManager.save() fails

问题描述

我写一个C＃应用程序（没有的WinForms）

I am writing a C# application(no WinForms).

看了约ConfigurationManager中多个线程我有下面的代码结束：

Having read several threads about ConfigurationManager i have ended with the following code:

public static string GetValue(string key)
{
    Configuration configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
    var settings = configFile.AppSettings.Settings;
    if (settings[key] == null)
        throw new ArgumentException("Requested unknown key from Application Configuration("+configFile.FilePath+")",key);
    System.Console.Out.WriteLine("Got "+ key + " = " + settings[key].Value);
    return settings[key].Value;
}

public static void SetValue(string key, string value)
{
    try
    {
        Configuration configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        var settings = configFile.AppSettings.Settings;

        settings.Remove(key);
        settings.Add(key, value);
        configFile.Save(ConfigurationSaveMode.Modified,true);
    }
    catch (Exception e)
    {
        Console.WriteLine("Error writing app settings:"+e.Message+e.StackTrace);
    }
}

当我打电话我得到这个例外congig.save （）;

I am getting this exception when i call congig.save(); :

Error writing app settings: Method failed with unexpected error code 1.   at System.Security.AccessControl.NativeObjectSecurity.CreateInternal(ResourceType resourceType, Boolean isContainer, String name, SafeHandle handle, AccessControlSections includeSections, Boolean createByName, ExceptionFromErrorCode exceptionFromErrorCode, Object exceptionContext)

   at System.Configuration.MgmtConfigurationRecord.SaveAs(String filename, ConfigurationSaveMode saveMode, Boolean forceUpdateAll)
   at AppConfig.SetValue(String key, String value) in e:\FsLink\ConduitCore\AppConfig.cs:line 37

这是怎么回事，我该如何解决？

What is happening and how can i fix it?

推荐答案

以下GrawCubes此话事实证明这是一个事实，即该文件夹是VirtualBox的共享文件夹。

Following GrawCubes remark it turns out it was the fact that the folder was a VirtualBox Shared Folder.
