C# - SORT LIST ELEMENTS

How to sort a List in Ascending Order?

The Sort() Method is used to sort a List in Ascending order.

Example :

using System.Collections.Generic;
    
public class MyApplication
{
    public static void Main(string[] args)
    {
        var x = new List<string>(){"Mohan", "Kriti", "Salim"};
        x.Sort();
        
        foreach (var data in x)  
        {  
            System.Console.WriteLine(data);  
        }
    }    
}

Output :

Kriti
Mohan
Salim

So, in the above code we have created a List and initialised to the variable x.

var x = new List<string>(){"Mohan", "Kriti", "Salim"};

Below is how the values are positioned in the List,

Then we have used the Sort() method to sort the List x in ascending order.

x.Sort();

And the List x gets sorted with Kriti as the first value, Mohan second and Salim as the third.

And we get the below output.

Output :

Kriti
Mohan
Salim

How to sort a List with numbers in Increasing Order?

Even here the Sort() Method is used to sort a List with numbers in Increasing/Deceasing Order.

At first let us see an example to sort a List with numbers in Increasing order.

Example :

using System.Collections.Generic;
    
public class MyApplication
{
    public static void Main(string[] args)
    {
        var x = new List<int>(){5, 3, 2, 4};
        x.Sort();
        
        foreach (var data in x)  
        {  
            System.Console.WriteLine(data);  
        }
    }    
}

Output :

2
3
4
5

So, in the above code we have created a List and initialised to the variable x.

var x = new List<int>(){5, 3, 2, 4};

Below is how the values are positioned in the List,

Then we have used the Sort() method to sort the List x in increasing order.

x.Sort();

And the numbers in the List x gets sorted.

And we get the below output.

Output :

2
3
4
5

Next, let us see, how to sort a List in Descending order.

How to sort a List with numbers in Descending Order?

Example :

using System.Collections.Generic;
    
public class MyApplication
{
    public static void Main(string[] args)
    {
        var x = new List<int>(){5, 3, 2, 4};
        x.Sort();
        x.Reverse();
        foreach (var data in x)  
        {  
            System.Console.WriteLine(data);  
        }
    }    
}

Output :

5
4
3
2

So, in the above code we have created a List and initialised to the variable x.

var x = new List<int>(){5, 3, 2, 4};

Below is how the values are positioned in the List,

Then we have used the Sort() method to sort the List x in increasing order.

x.Sort();

Then we have used the Reverse() method to reverse the List

x.Reverse();

And the List x gets sorted in decreasing order.

And we get the below output.

Output :

5
4
3
2
