读键值对到字典从app.config中configSection [英] Reading keyvalue pairs into dictionary from app.config configSection

问题描述

我目前在我的一个应用程序中设置像这样一个app.config：

I currently have an app.config in an application of mine set up like so:

 <?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="DeviceSettings">
      <section name="MajorCommands" type="System.Configuration.DictionarySectionHandler"/>
    </sectionGroup>
  </configSections>
  <appSettings>
    <add key="ComPort" value="com3"/>
    <add key="Baud" value="9600"/>
    <add key="Parity" value="None"/>
    <add key="DataBits" value="8"/>
    <add key="StopBits" value="1"/>
    <add key="Ping" value="*IDN?"/>
    <add key="FailOut" value="1"/>
  </appSettings>
  <DeviceSettings>
    <MajorCommands>
      <add key="Standby" value="STBY"/>
      <add key="Operate" value="OPER"/>
      <add key="Remote" value="REMOTE"/>
      <add key="Local" value="LOCAL"/>
      <add key="Reset" value="*RST" />
    </MajorCommands>
  </DeviceSettings>
</configuration>

我现在的目标是的foreach或只是读取MajorCommands所有值成字典<字符串，字符串> 格式为词典<关键字，值> 。我试着用System.Configuration几种不同的方法，但似乎没有任何工作，我一直无法找出有什么细节我确切的问题。是否有这样做的正确方法？

My current objective is to foreach or simply read all values from MajorCommands into a Dictionary<string, string> formatted as Dictionary<key, value>. I've tried several different approaches using System.Configuration but none seem to work and I haven't been able to find any details out there for my exact question. Is there any proper way to do this?

推荐答案

使用 ConfigurationManager中类你可以从的app.config 文件全断面为的Hashtable ，你可以转换为词典如果你想：

using ConfigurationManager class you can get whole section from app.config file as Hashtable which you can convert to Dictionary if you want to:

var section = (ConfigurationManager.GetSection("DeviceSettings/MajorCommands") as System.Collections.Hashtable)
                 .Cast<System.Collections.DictionaryEntry>()
                 .ToDictionary(n=>n.Key.ToString(), n=>n.Value.ToString());

您需要添加引用 System.Configuration 组装
