Concatenating strings with log4net

Question

Is it possible to do something like this with log4net logging ?

logger.Debug("username : {0} password : {1} server : {2}",username,server,password)

Or am i only left with the option of ugly "+" concatenating.

Answer 1

Yes you can, in two ways

log.Debug(String.format("username : {0} password : {1} server : {2}",username,server,password));

Or use default API

logger.DebugFormat("username : {0} password : {1} server : {2}",username,server,password)

Answer 2

You can also use the new string interpolation feature of C# 6.0:

logger.Debug($"username : {username} password : {password} server : {server}")
