Code snippet to make a ToJson extension method for objects in C#. Relies on NewtonSoft.Json Nuget.

JsonExtensions.cs

public static class ObjectExtensions
{
    /// <summary>
    /// The string representation of null.
    /// </summary>
    private static readonly string Null = "null";
    
    /// <summary>
    /// The string representation of exception.
    /// </summary>
    private static readonly string Exception = "Exception";

    /// <summary>
    /// To json.
    /// </summary>
    /// <param name="value">The value.</param>
    /// <returns>The Json of any object.</returns>
    public static string ToJson(this object value)
    {
        if (value == null) return Null;

        try
        {
            string json = JsonConvert.SerializeObject(value);
            return json;
        }
        catch (Exception exception)
        {
            //log exception but dont throw one
            return Exception;
        }
    }
}

Cool!

For me, I love to log formatted JSON. Maybe add a parameter for Formatting and default to Formatting.None?

public static string ToJson(this object value, Formatting formatting = Formatting.None)
{
    if (value == null) return Null;
    try
    {
         return JsonConvert.SerializeObject(value, formatting);
    }
    catch
    {
         //log exception but dont throw one
         return Exception;
    }
}

string formatted_string = new SomeObject().ToJson(Formatting.Indented)
