C# 操作 config 取出指定节点的值

Question

求教一个问题 
我想取出在config文件里的某个节点，节点如下<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="SAP.Middleware.Connector">
      <sectionGroup name="ClientSettings">
        <section name="DestinationConfiguration" type="SAP.Middleware.Connector.RfcDestinationConfiguration,sapnco"/>
      </sectionGroup>
    </sectionGroup>
  </configSections>
  <SAP.Middleware.Connector>
    <ClientSettings>
      <DestinationConfiguration>
        <destinations>
          <add NAME="Conn" USER="KY_PG01" PASSWD="ky@123" CLIENT="002" SYSNR="10" ASHOST="192.168.0.22" LANG="ZH" GROUP="PUBLIC" MAX_POOL_SIZE="5"></add>
        </destinations>
      </DestinationConfiguration>
    </ClientSettings>
  </SAP.Middleware.Connector>
</configuration>
我想取到并且能修改<SAP.Middleware.Connector>节点下的<add>节点里面各个属性的值。希望各位大大能帮帮小妹，有代码最好了哦！
祝大家中秋快乐啊！

Answer 1

就当成xml文件来读就可以了。
 XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load("test.config");            XmlNode node = xmlDocument.SelectSingleNode("configuration/SAP.Middleware.Connector/ClientSettings/DestinationConfiguration/destinations/add");            Console.WriteLine(node.Attributes["NAME"].InnerText);//其它属性类似获取 这里输出Conn

Answer 2

XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load("test.config");            XmlNode node = xmlDocument.SelectSingleNode("configuration/SAP.Middleware.Connector/ClientSettings/DestinationConfiguration/destinations/add");            node.Attributes["NAME"].InnerText = "ConnStrings";//给指定的属性赋值
            xmlDocument.Save("test.config");//最关键的，一定要保存一下。

Answer 3

            //读取Config配置文件
            string ConfigFileName = Process.GetCurrentProcess().MainModule.ModuleName + ".config";
            XmlDocument XmlDoc = new XmlDocument();
            MemoryStream Ms = new MemoryStream(File.ReadAllBytes(ConfigFileName));
            XmlDoc.Load(Ms);
            Ms.Close();
            XmlNode Node = XmlDoc.SelectSingleNode("configuration/SAP.Middleware.Connector/ClientSettings/DestinationConfiguration/destinations/add");            //取到Name和Value
            string Str = string.Empty;
            foreach (XmlAttribute item in Node.Attributes)
            {
                Str += string.Format("Name:{0} \t Value:{1} \n", item.Name, item.Value);
            }
            MessageBox.Show(Str);            //修改属性
            foreach (XmlAttribute item in Node.Attributes)
            {
                item.Value = "修改Value";
            }            //保存覆盖到原文件
            XmlDoc.Save(ConfigFileName);
