C# 循环通过configration部分读取它'；使用C语言创建s元素#

我有一个配置文件，类似于：

<logonurls>
  <othersettings>
    <setting name="DefaultEnv" serializeAs="String">
      <value>DEV</value>
    </setting>
  </othersettings>
  <urls>      
    <setting name="DEV" serializeAs="String">
      <value>http://login.dev.server.com/Logon.asmx</value>
    </setting>
    <setting name="IDE" serializeAs="String">
      <value>http://login.ide.server.com/Logon.asmx</value>
    </setting>
  </urls>
  <credentials>
    <setting name="LoginUserId" serializeAs="String">
      <value>abc</value>
    </setting>
    <setting name="LoginPassword" serializeAs="String">
      <value>123</value>
    </setting>
  </credentials>    
</logonurls>

config是包含配置文件中数据的配置变量。

将其转换为正确的XML并在节点内搜索：

private static string GetKeyValue(string keyname)
{
    string rtnValue = String.Empty;
    try
    {
        ConfigurationSectionGroup sectionGroup = config.GetSectionGroup("logonurls");
        System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
        doc.LoadXml(sectionGroup);

        foreach (System.Xml.XmlNode node in doc.ChildNodes)    
        {    
            // I want to loop through all the settings element of the section
            Console.WriteLine(node.Value);
        }
    }
    catch (Exception e)
    {
    }

    return rtnValue; 
}

请注意：如果将其转换为XML，还可以使用XPath获取值

System.Xml.XmlNode element = doc.SelectSingleNode("/NODE");

将配置文件加载到XmlDocument中，按名称获取XmlElement（设置要读取的值），然后尝试以下代码

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.LoadXml(xmlfilename);

XmlElement elem = doc.GetElementByName("keyname");
var allDescendants = myElement.DescendantsAndSelf();
var allDescendantsWithAttributes = allDescendants.SelectMany(elem =>
    new[] { elem }.Concat(elem.Attributes().Cast<XContainer>()));

foreach (XContainer elementOrAttribute in allDescendantsWithAttributes)
{
    // ...
}

System.Xml.XmlDocument doc=new System.Xml.XmlDocument（）；
doc.LoadXml（xmlfilename）；
XmlElement elem=doc.GetElementByName（“keyname”）；
var allsubstands=myElement.substantsandself（）；
var allgenderantswithattributes=allsubstands.SelectMany（elem=>
新[]{elem}.Concat（elem.Attributes（）.Cast（））；
foreach（所有子代属性中的XContainer ElementAttribute）
{
// ...
}

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.LoadXml(xmlfilename);

XmlElement elem = doc.GetElementByName("keyname");
var allDescendants = myElement.DescendantsAndSelf();
var allDescendantsWithAttributes = allDescendants.SelectMany(elem =>
    new[] { elem }.Concat(elem.Attributes().Cast<XContainer>()));

foreach (XContainer elementOrAttribute in allDescendantsWithAttributes)
{
    // ...
}
