Method 1: Using Split Method

We can convert a string to a collection using the Split method. This method splits a string into an array of substrings based on a specified delimiter. 

using System;

class Program
{
    static void Main()
    {
        string data = "red,blue,orange,white,vilot";
        string[] colors = data.Split(',');

        Console.WriteLine("String to Collection using Split Method:");
        foreach (var color in colors)
        {
            Console.WriteLine(color);
        }
        Console.ReadKey();
    }
}

Output:

String to Collection using Split Method:
red
blue
orange
white
vilot

In this example, the string "red,blue,orange,white,vilot" is split into an array of strings using the comma (,) as the delimiter.

Method 2: Using LINQ

This LINQ allows for more complex operations on collections. Check the below program.

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        string data = "1,2,3,4,5";
        var numbers = data.Split(',').Select(int.Parse).ToList();

        Console.WriteLine("String to Collection using LINQ:");
        foreach (var number in numbers)
        {
            Console.WriteLine(number);
        }
    }
}

Output:

String to Collection using LINQ:
1
2
3
4
5

This program converts a string of comma-separated numbers into a list of integers using LINQ's Select method.
