C# private, static, and readonly

Question

I was reviewing some code for log4net and I came across this.

private static readonly ILog logger = LogManager.GetLogger(typeof(AdminClient));

Answer 1

static in c# means the member is associated with the class, and not with an instance of the class. Readonly is important because in c# most variables, and this one in particular, are reference variables. The readonly means that this variable will always reference the same logger.
