Using Serilog to log generic object

Question

Is it possible to log in a method where the incoming argument is generic? For example ``` public async Task<TResult> Handle(TQuery query) { var watch = Stopwatch.StartNew(); var result = await _handler.Handle(query); watch.Stop(); Serilog.Log.Logger.Information("Processed {@" + query.GetType().Name + "} in {Elapsed} ms", query.GetType().Name, watch.ElapsedMilliseconds); return result; } ``` Note in the above, I'm using string concatenation in the template and I'm not sure this is a best practice. Is there another way to log the incoming object?

Accepted Answer

Have you considered just passing the type of the query object through, or the query object itself? E.g.:

```
Log.Information("Processed {@Query} in {Elapsed} ms", query, watch.ElapsedMilliseconds);
```

This will print output like:

```
Processed SomeQuery { SomeProp = "foo" } in 100 ms
```
