.NET Interactive - how to change collection output size

Question

I'm using .NET Interactive notebook inside VS Code and want to change the number of printed out elements:

var x = Enumerable.Range(0,21);
x.Display();

Only first 20 element are shown in the the output:

Can I somehow increase the size of output?

Answer 1

You can use Formatter from Microsoft.DotNet.Interactive.Formatting namespace to change the size of the output:

using Microsoft.DotNet.Interactive.Formatting; 
Formatter.ListExpansionLimit = 25;

Docs:

• Formatter.ListExpansionLimit = 20

  Gets or sets the limit to the number of items that will be written out in detail from an IEnumerable sequence.

• Formatter<T>.ListExpansionLimit = (not set)

  An optional type-specific list expansion limit
