ObjectDumper is a utility which aims to serialize C# objects to string for debugging and logging purposes.

This library is available on NuGet: https://www.nuget.org/packages/ObjectDumper.NET/ Use the following command to install ObjectDumper using NuGet package manager console:

PM> Install-Package ObjectDumper.NET

You can use this library in any .NET project which is compatible to PCL (e.g. Xamarin Android, iOS, Windows Phone, Windows Store, Universal Apps, etc.)

Serialization, the process of converting a complex object to a machine-readable or over-the-wire transmittable string, is a technique often used in software engineering. A well-known serializer is Newtonsoft.JSON which serializes .NET objects to the data representation format JSON.

ObjectDumper.NET provides two excellent ways to visualize in-memory .NET objects:

• DumpStyle.Console: serialize objects to human-readable strings, often used to write complex C# objects to log files.
• DumpStyle.CSharp: serialize objects to C# initializer code, which can be used to compile a C# object again.

The following sample program uses DumpStyle.Console to write C# objects to the console output:

static void Main(string[] args)
{
    var persons = new List<Person>
    {
        new Person { Name = "John", Age = 20, },
        new Person { Name = "Thomas", Age = 30, },
    };

    var personsDump = ObjectDumper.Dump(persons);

    Console.WriteLine(personsDump);
    Console.ReadLine();
}

//CONSOLE OUTPUT:
{ObjectDumperSample.Netfx.Person}
  Name: "John"
  Age: 20
{ObjectDumperSample.Netfx.Person}
  Name: "Thomas"
  Age: 30

The following sample program uses DumpStyle.CSharp to write C# initializer code from in-memory to the console output:

static void Main(string[] args)
{
    var persons = new List<Person>
    {
        new Person { Name = "John", Age = 20, },
        new Person { Name = "Thomas", Age = 30, },
    };

    var personsDump = ObjectDumper.Dump(persons, DumpStyle.CSharp);

    Console.WriteLine(personsDump);
    Console.ReadLine();
}

//CONSOLE OUTPUT:
var listOfPersons = new List<Person>
{
  new Person
  {
    Name = "John",
    Age = 20
  },
  new Person
  {
    Name = "Thomas",
    Age = 30
  }
};
