Introduction
If I want to use the list element as an array element then it is necessary to convert the list into an array, so in this article I convert the list into an array and array into the list. In this article I also explain how to find the maximum element in the list and how to find the minimum element in list.
Convert List to array
In this you can see how to convert your List to an array, using the integer element type, this example creates a new List and populates it with some integers. The List is a constructed type and can only hold integer values. Next it uses ToArray on the List.
namespace ConsoleApplication8
{
class Program
{
static void Main(string[] args)
{
//creation of list<>
List<int> number = new List<int>();
//add the elements in the list
number.Add(10);
number.Add(20);
number.Add(15);
number.Add(25);
number.Add(30);
number.Add(35);
number.Add(40);
number.Add(45);
//creation of an array
int[] a = number.ToArray();
//display the array element
Console.WriteLine("the array elements are:");
foreach (int i in a)
{
Console.WriteLine(i);
}
}
}
}
Output

Convert array to List
In this example we see how to convert an array of any number of elements to a List that has the same type of elements. First, I initialize a new string[] array containing 7 strings. Next it converts the array to a List with the new List constructor.
namespace ConsoleApplication8
{
class Program
{
static void Main(string[] args)
{
//create array
string[] s = new string[] { "sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday" };
//create list
List<string> days = new List<string>(s);
Console.WriteLine("The list element is:");
foreach (string i in days)
{
Console.WriteLine(i);
}
}
}
}
Output

Find maximum element
Write the following code to find the maximum element in the list. For this we use the max() method of the list.
namespace ConsoleApplication8
{
class Program
{
static void Main(string[] args)
{
List<int> a = new List<int>();
a.Add(10);
a.Add(20);
a.Add(1);
a.Add(30);
a.Add(67);
Console.WriteLine("list elements are:");
foreach (int i in a)
{
Console.WriteLine(i);
}
int max = a.Max();
Console.WriteLine("Maximum element in the list is:" + max);
}
}
}
Output

Find minimum element
Write the following code to find the minimum element in the list. For this we use the min() method of the list.
namespace ConsoleApplication8
{
class Program
{
static void Main(string[] args)
{
List<int> a = new List<int>();
a.Add(10);
a.Add(20);
a.Add(1);
a.Add(30);
a.Add(67);
Console.WriteLine("list elements are:");
foreach (int i in a)
{
Console.WriteLine(i);
}
int min = a.Min();
Console.WriteLine("Minimum element in the list is:" + min);
}
}
}
Output

Summary: In this article I explain how to convert the array into a list and a list into an array and also to find the maximum and minimum number from the list.
