在serilog中使用C＃参数

Question

Just starting using Serilog + ElasticSearch and was wondering if there is an elegant way to log a params object array in one log entry. So far the only way I have been able to manage it is looping through each params which creates a separate log entry for each one. Any way to combine them into one log entry?

Thanks!

Sample:

public static void MethodEntry<T>(string methodName, params object[] parameters)
{
    if (parameters.Length > 0)
        foreach (var param in parameters) // Will create parameters.Length number of log entries
            Log.ForContext(typeof(T)).Debug("Entering {MethodName} with {@Param}", methodName, param);
    else
        Log.ForContext(typeof(T)).Debug("Entering {MethodName}", methodName);
}

EDIT:

Sinks used:

• Serilog
• Serilog.Sinks.Elasticsearch (which includes The File, PeriodicBatching, & RollingFile Sinks)
• Couple Enrichers like Environment and ThreadId

Answer 1

If you know the specific type of your Sender object you can use the following feature of Serilog to avoid logging of the not required information:

Log.Logger = new LoggerConfiguration()
    .Destructure.ByTransforming<YOUR_SENDER_TYPE>(
        r => new { firstValue = r.firstValue, secondValue = r.secondValue })
    .WriteTo .... 

More about logging structured data you can find in the official documentation Serilog Structured Data

Answer 2

public static void MethodEntry<T>(string methodName, params object[] parameters)
{
    Log.ForContext<T>()
        .ForContext("Parameters", parameters)
        .Debug("Entering {MethodName}", methodName);
}

This should do what you're after.
