Efficient Logging in C# Using Serilog

Logging is a fundamental part of software development. It allows you to gain insights into the application's behavior and troubleshoot issues more efficiently. In this post, we will discuss how to log key details, such as the class path, method name, and line number of log entries in a .NET Framework 4.6.1 application using Serilog.

Problem Statement

You want to enhance your logging system in C# to automatically include information about which class and method log entries are coming from. This includes logging the exact line number, allowing for better debugging and documentation of your system's behavior.

Solution Overview

To achieve this, there are several approaches you can take. Here we will discuss two solutions: using the Serilog.Enrichers.StackTrace package and leveraging C# compiler services with attributes like CallerMemberName, CallerFilePath, and CallerLineNumber.

Solution 1: Utilizing Serilog Enricher

The first approach is the simplest as it utilizes an external package called Serilog.Enrichers.StackTrace to automatically enrich your logs with stack trace information.

Step-by-Step Implementation

Install the NuGet Package:
First, you need to install the Serilog.Enrichers.StackTrace package into your project.

Configure Serilog: Modify your Serilog configuration to incorporate the enricher.

Solution 2: Using C# Compiler Services

Alternatively, you can achieve similar results without additional packages by using C# compiler service attributes.

Step-by-Step Implementation

Create a custom logging function:
Create a static class for Serilog extensions to handle the detailed logging.
