I have made for this purpose configuration program which modifies
.log4net.config and replaces paths for all appenders.
Remember, config is normal XML document, so you can modify it through
DOM model.
Here is code snippet which does it. Do not compile, but for inspiration:
public void UpdateAppenderFileDirs(string dirName)
{
System.Xml.XmlNodeList xmlNList;
xmlNList =
_configXmlDoc.DocumentElement.SelectNodes("/configuration/log4net/appender/file");
foreach (System.Xml.XmlNode node in xmlNList)
{
XmlNode attr = node.Attributes.GetNamedItem("value");
if (attr == null)
{
throw (ExcUtils.XmlAttributeNotFound("value", node));
}
attr.InnerXml = Path.Combine(dirName, Path.GetFileName(attr.InnerXml));
}
}
