Hello,

It is on Windows platform, and you know the file path, right? If so, please refer to the following code:

#if WINDOWS
var stream = await FileSystem.OpenAppPackageFileAsync("a.log");// your log file in Raw folder
XmlDocument XNLDOC = new XmlDocument();
XNLDOC.Load(stream);
XmlNodeList list = XNLDOC.SelectNodes("configuration");
XmlNode configuration = list[0];
XmlNodeList listLog4List = configuration.SelectNodes("log4net");
XmlNode appender = listLog4List[0];
XmlNode fileNodes = appender.ChildNodes[1];
XmlNodeList appenderList= fileNodes.SelectNodes("file");
XmlNode itemNode = appenderList[1];
string fileValue = itemNode.Attributes["value"].Value;
Debug.WriteLine(fileValue);
 
//foreach (XmlNode item in appenderList)
//{
//    string value = item.OuterXml;
//    string nodeValue = item.Attributes["value"].Value;
//    Debug.WriteLine("{0},--{1}", value,nodeValue);
//}
#endif
