Serilog: How to configure a logger in an Abstract class and have a derived type as the Context?

[stephenpatten]

Hello,

Looking for a way to have the derived class context be used when logging in the derived class. Is this possible?

Thank you,
Stephen

Yes, I think so, if you initialize the logger in the constructor:

class SomethingAbstract
{
   protected ILogger Log { get; }

   protected SomethingAbstract()
   {
       Log = Log.ForContext(GetType());
   }

// ...

Or another variation, if you want to ensure messages from the base class are tagged with that type:

abstract class SomethingAbstract
{
    readonly ILogger _log = Log.ForContext<SomethingAbstract>();

    // Here's your base class implementation, using _log for logging
}

abstract class SomethingToDeriveFrom : SomethingAbstract
{
   protected ILogger Log { get; }

   protected SomethingToDeriveFrom()
   {
       Log = Log.ForContext(GetType());
   }
}

// Derived classes inherit from SomethingToDeriveFrom and use Log for logging
