I have a linq expression which returns a list of objects. I want to dump that output to console in a pretty tabular format.

I like to use JSON.NET for serializing objects to string (in pretty tabular format). I also like to create extension method Dump() which outputs serialized object to console:

public static void Dump(this object value)
{
     Console.WriteLine(JsonConvert.SerializeObject(value, Formatting.Indented));
}

Usage is simple:

items.Dump();

Thansk a lot Sergey. Can I use the same method with a datatable as well??

Sergey Berezovskiy Over a year ago

@gargmanoj yes, it will serialize DataTable also into array of objects like this [ { "Column1": Value1, "Column2": Value2 }, { "Column1": Value3, "Column2": Value4 }]

I am getting an exception "Self referencing loop detected for property 'Table' with type 'System.Data.DataTable'. Path 'Columns[0]'." when i use it with datatable.. using as dt.Dump<DataTable>();

@gargmanoj I think you need to add loops ignoring, like described here stackoverflow.com/questions/13510204/…
