Write a program in C# Sharp to find maximum and minimum element in an array ?

using System;  
public class Exercise9
{  
    public static void Main() 
{
    int[] arr1= new int[100];
    int i, mx, mn, n;	
       Console.Write("\n\nFind maximum and minimum element in an array :\n");
       Console.Write("--------------------------------------------------\n");	
       Console.Write("Input the number of elements to be stored in the array :");
	   n= Convert.ToInt32(Console.ReadLine());    
       Console.Write("Input {0} elements in the array :\n",n);
       for(i=0;i<n;i++)
            {
	      Console.Write("element - {0} : ",i);
		  arr1[i] = Convert.ToInt32(Console.ReadLine());  
	    }
    mx = arr1[0];
    mn = arr1[0];
    for(i=1; i<n; i++)
    {
        if(arr1[i]>mx)
        {
            mx = arr1[i];
        }
        if(arr1[i]<mn)
        {
            mn = arr1[i];
        }
    }
    Console.Write("Maximum element is : {0}\n", mx);
    Console.Write("Minimum element is : {0}\n\n", mn);
  }
