How to sort one-dimensional array in ascending order using non-static method?

Set the unsorted array first.

int[] list = {87, 45, 56, 22, 84, 65};

Now use a nested for loop to sort the list, which is passed to a function.

for(int i=0; i< arr.Length; i++) {
   for(int j=i+1; j<arr.Length; j++) {
      if(arr[i]>=arr[j]) {
         temp=arr[j];
         arr[j]=arr[i];
         arr[i]=temp;
      }
   }
   Console.Write(arr[i] + " ");
}

The following is the complete code to sort one-dimensional array in ascending order using non-static method.

Example

using System;
namespace Demo {
   public class MyApplication {
      public static void Main(string[] args) {
         int[] list = {87, 45, 56, 22, 84, 65};
         Console.WriteLine("Original Unsorted List");
         foreach (int i in list) {
            Console.Write(i + " ");
         }
         MyApplication m = new MyApplication();
         m.sortFunc(list);
      }
      public void sortFunc(int[] arr) {
         int temp = 0;
         Console.WriteLine("\nSorted List");
         for(int i=0; i< arr.Length; i++) {
            for(int j=i+1; j<arr.Length; j++) {
               if(arr[i]>=arr[j]) {
                  temp=arr[j];
                  arr[j]=arr[i];
                  arr[i]=temp;
               }
            }
            Console.Write(arr[i] + " ");
         }
      }
   }
}

Output

Original Unsorted List
87 45 56 22 84 65
Sorted List
22 45 56 65 84 87
