How Can I Easily Dump C# Objects to Logs as JSON?

Dumping Objects to Logs in C#

The Visual Studio Immediate window provides a convenient way to view an object's state at runtime. By simply typing "? objectname," developers can extract a formatted dump of the object. However, a similar functionality is often needed in logging scenarios.

Is there a straightforward approach to replicate this functionality in code?

One effective solution is to leverage the Newtonsoft.Json library. By utilizing a custom class with a serialization method, developers can easily convert an object to a JSON representation.

Consider the following code snippet:

using Newtonsoft.Json;

public static class Logger
{
    public static string Dump(object obj)
    {
        return JsonConvert.SerializeObject(obj);
    }
}

To use this class, simply call its "Dump" method, passing in the object to be serialized:

var dump = Logger.Dump(myObject);

The result will be a JSON string representing the object's state. In the Visual Studio Immediate Window, this string can be visualized by assigning it to a variable and selecting the "Json visualizer" option from the Value column's dropdown menu.
