What is the C# equivalent for reducing the Slice values in Python?

List<T>.RemoveRange(Int32, Int32) Method is used to remove a range of elements from the List<T>. 

Example 1:

// C# Program to remove a range of

// elements from the List

using System;

using System.Collections;

using System.Collections.Generic;

class Geeks {

    // Main Method

    public static void Main(String[] args)

    {

        // Creating an List<T> of strings

        List<String> firstlist = new List<String>();

        // Adding elements to List

        firstlist.Add("Geeks");

        firstlist.Add("For");

        firstlist.Add("Geeks");

        firstlist.Add("GFG");

        firstlist.Add("C#");

        firstlist.Add("Tutorials");

        firstlist.Add("GeeksforGeeks");

        // Displaying the elements of firstlist

        Console.WriteLine("Elements in List:\n");

        foreach(string ele in firstlist)

        {

            Console.WriteLine(ele);

        }

        // removing 1 elements starting

        // from index 3

        firstlist.RemoveRange(3, 1);

        Console.WriteLine("");

        // Displaying the updated List

        Console.WriteLine("After Removing of elements:\n");

        // Displaying the elements in List

        foreach(string ele in firstlist)

        {

            Console.WriteLine(ele);

        }

    }

}

Output:

                 Elements in List:

                 Geeks

                 For

                 Geeks

                 GFG

                 C#

                 Tutorials

                 GeeksforGeeks

                 After Removing of elements:

                Geeks

                For

                Geeks

                C#

                Tutorials

Hi David and Manav

We can use Linq's .Where() and .Select() methods to wrangle the data since History returns an IEnumerable of Slice objects.

var df = History(...).Where(x => x != null).Select(x => x.Close);

Or if you'd like it to be paired with time:

var df = History(...).Where(x => x != null).ToDictionary(x => x.EndTime, x => x.Close);
