问题描述

我有一个WinForms有一个app.config有一堆被设置在运行时，并保存用户范围设置的.exe文件。
我希望能够使用的WinForms应用更改并保存设置，然后点击按钮做基础上，这些设置一些工作。
我也想从在Sep同config文件读取用户设置。控制台应用程序，所以我可以安排工作要做作为一个计划任务。
什么是能够做到这一点的最好办法

I have a WinForms .exe with an App.config that has a bunch of User Scoped Settings that are set at runtime and saved. I want to be able to use the WinForms app to change and save the settings and then click on button to do some work based on the those settings. I also want to read the user settings in the same .config file from a sep. console app so I can schedule to work to be done as a scheduled task. What is the best way to be able to do this?

更​​新：
我试图在一些描述使用ConfigurationManager.OpenExeConfiguration的reccommendation 。像这样的答案

Update: I tried the reccommendation of using ConfigurationManager.OpenExeConfiguration as described in some of the answers like so.

Configuration config = ConfigurationManager.OpenExeConfiguration("F:\\Dir\\App.exe");

但是当我尝试检索用户设置像这样。

but when I try to retrieve a User Setting like so.

string result = config.AppSettings.Settings["DB"].ToString();

我得到一个空引用错误。

I get a Null reference error.

从代码的EXE但是下面正确返回数据库名称。

From code in the exe however the following correctly returns the DB name.

Properties.Settings.Default.DB

我要去哪里错了。

更新2：

因此，基于一些答案下面我现在可以使用以下方法来检索文件user.config我感兴趣的是从九月的部分的原始XML。 。ConsoleApp

So based on some of the answers below I now can use the following to retrieve the raw XML of the section of the user.config file I am interested in from sep. ConsoleApp.

System.Configuration.ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
fileMap.ExeConfigFilename = @"D:\PathHere\user.config";
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap,ConfigurationUserLevel.None);
System.Configuration.DefaultSection configSection = (System.Configuration.DefaultSection)config.GetSection("userSettings");
string result = configSection.SectionInformation.GetRawXml();
Console.WriteLine(result);

不过，我仍然无法直接拔掉的价值，因为我感兴趣的特定元素。

But I am still unable to just pull the value for the specific element I am interested in.

推荐答案

这应该这样做：

var clientSettingsSection = (System.Configuration.ClientSettingsSection)(ConfigurationManager.GetSection("userSettings/YourApplicationName.Properties.Settings"));
var setting = clientSettingsSection.Settings.Get("yourParamName_DB_");
string yourParamName_DB = ((setting.Value.ValueXml).LastChild).InnerText.ToString();
