c# - representing an XML config file with an IXmlSerializable class -

I am writing in C # and representing an XML configuration file via the IXmlSerializable class I am trying to do How can I represent nested elements in my config file, though, such as logLevel :

  & lt ;? Xml version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Configuration & gt; & Lt; Logging & gt; & Lt; LogLevel & gt; Error & lt; / LogLevel & gt; & Lt; / Logging & gt; & Lt; Credit & gt; & Lt; Users & gt; User123 & lt; / User & gt; & Lt; Host & gt; Local Host & lt; / Host & gt; & Lt; Password & gt; Pass123 & lt; / Password & gt; & Lt; / Credibility & gt; & Lt; Credit & gt; & Lt; Users & gt; User456 & lt; / User & gt; & Lt; Host & gt; My.other.domain.com & lt; / Host & gt; & Lt; Password & gt; Pass456 & lt; / Password & gt; & Lt; / Credibility & gt; & Lt; / Configuration & gt; There is an element called   
  log level  which represents all possible values ​​for the  logLevel  tag. Tags within  credentials  come in the form of all strings. In my class, which is called  DLLConfigFile , the following was the following: 
 
  [XmlElement (element name = "logleval", datatype = "logleval")] public logleval loglevel ;  
 
 However, this is not working because  & lt; LogLevel & gt;  is not within the root node of the XML file, it is a node in depth to  & lt; Logging & gt; .  & lt; Credential & gt; For nodes, I think I'll need a second class, the  address of the credentials , and there is a property in the form of: 
 
 < Code> [XmlElement (ElementName = "credentials", datatype = "address of credentials")] Public credentials [edit] AllCredentials; Edit:  OK: I tried Robert Love's suggestion and created a  logging address  class. However, my test fails: 
 
  var xs = new XML serializer (typef (DLLConfigFile)); (Var StreamReader = New Stream Reader (Stream)) {XmlReader Reader = New XmlTextReader (Stream Reader); (Var Stream = New File Stream (_configPath, FileMode.Open, FileAccess.Read, FileShare Reid)); Var file = (DLLConfigFile) xs.Deserialize (Reader); Assert.IsNotNull (file); Logging extension logging = file. Leasing; Assert.IsNotNull (login); // here fails LogLevel logLevel = logging.LogLevel; Assert.IsNotNull (LogLevel); Assign. AEQWELL (EXPECTED_LOG_LEVEL, logelveled); }}  
 
 I'm definitely  & lt; Logging & gt; I'm filing a test with . What these squares look like: 
  log level  
 

and then create the logging property on your base class which is a new type.
