How to log complex object using Serilog in valid json format?

Serilog provides a way to log complex objects in JSON format using the WriteTo.Console() method. By default, this method formats log entries as plain text, but you can customize the format by providing a formatter.

Here's an example of how to log a complex object using Serilog in valid JSON format:

using Serilog; using Serilog.Formatting.Json; // Create a new logger configuration var loggerConfiguration = new LoggerConfiguration() .WriteTo.Console(new JsonFormatter()); // Create a logger instance var logger = loggerConfiguration.CreateLogger(); // Create a complex object to log var complexObject = new { Name = "John Doe", Age = 30, Address = new { Street = "123 Main St", City = "Anytown", State = "CA", Zip = "12345" } }; // Log the complex object logger.Information("{@ComplexObject}", complexObject);

In this example, we're creating a new logger configuration that writes log entries to the console using the JsonFormatter() formatter. We're then creating a logger instance from the configuration.

Next, we're creating a complex object to log, which includes a nested object.

Finally, we're logging the complex object using the Information() method and including the object as a structured argument with the {@ComplexObject} syntax. This tells Serilog to log the object as a JSON object, with each property as a key-value pair.

When you run this code, the output will be a valid JSON object that looks like this:

{ "Name": "John Doe", "Age": 30, "Address": { "Street": "123 Main St", "City": "Anytown", "State": "CA", "Zip": "12345" } }

By using the JsonFormatter() formatter and the {@ComplexObject} syntax, you can log complex objects in valid JSON format with Serilog.

Examples

  1. "Serilog log complex object to JSON"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; Log.Information("Complex object: {@ComplexObject}", complexObject);

    Description: Use the @ symbol with the object in the log message to instruct Serilog to serialize the complex object to JSON.

  2. "Serilog log complex object as JSON string"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; Log.Information("Complex object: {ComplexObject}", JsonConvert.SerializeObject(complexObject));

    Description: Serialize the complex object to a JSON string manually using JsonConvert.SerializeObject and include it in the log message.

  3. "Serilog log nested complex objects to JSON"

    Code:

    var nestedObject = new { NestedProperty = "NestedValue" }; var complexObject = new { Property1 = "Value1", Property2 = nestedObject }; Log.Information("Complex object with nested: {@ComplexObject}", complexObject);

    Description: Include nested complex objects in the log message using the @ symbol for each level of the object hierarchy.

  4. "Serilog log complex object with custom JSON property names"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; Log.Information("Custom names: {PropertyName1:Prop1, PropertyName2:Prop2}", complexObject);

    Description: Specify custom JSON property names using the format {PropertyName:JsonName} in the log message.

  5. "Serilog log complex object with excluded properties"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = "SensitiveData" }; Log.Information("Excluding sensitive data: {@ComplexObject}", new { complexObject.Property1 });

    Description: Create an anonymous object with only the properties you want to include in the log, excluding sensitive data.

  6. "Serilog log complex object with nested arrays in JSON"

    Code:

    var nestedArray = new[] { "Item1", "Item2" }; var complexObject = new { Property1 = "Value1", Property2 = nestedArray }; Log.Information("Complex object with array: {@ComplexObject}", complexObject);

    Description: Log a complex object containing nested arrays, and Serilog will serialize the arrays to JSON format.

  7. "Serilog log complex object with custom JSON formatting"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; Log.Information("Custom formatting: {ComplexObject:lj}", complexObject);

    Description: Apply custom JSON formatting using Serilog's formatting options, such as :lj for JSON.

  8. "Serilog log complex object with property name quoting"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; Log.Information("Quoting property names: {@'ComplexObject'}", complexObject);

    Description: Use the @'ObjectName' syntax to include property name quoting in the JSON output.

  9. "Serilog log complex object with indented JSON"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; Log.Information("Indented JSON: {@ComplexObject:lj}", complexObject);

    Description: Enable indented JSON formatting by using :lj in the log message.

  10. "Serilog log complex object with conditional logging"

    Code:

    var complexObject = new { Property1 = "Value1", Property2 = 42 }; if (condition) { Log.Information("Conditional logging: {@ComplexObject}", complexObject); }

    Description: Conditionally log a complex object based on a specific condition using an if statement.
