For example we have list of integers:

18, 13, 23, 12, 27



Initially large = 18;

In first comparison 	small > 13; true ,  Now small becomes  13. 
In second comparison 	small > 23; false	,  Now small is 13.
In third comparison 	small > 12; true ,  Now small becomes  12.
In forth comparison 	small > 27; false , Now small is  12.

Consider the example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main()
		{
			int i       = 0;
			int small   = 0;
			//integer array declaration
			int[] arr   = new int[5];

			Console.WriteLine("Enter array elements : ");
			//read array elements
			for (i = 0; i < arr.Length; i++)
			{
				Console.Write("Element[" + (i + 1) + "]: ");
				arr[i] = int.Parse(Console.ReadLine());
			}

			//assign fist element to the 'small' 
			//compare it with other array elements
			small = arr[0];

			for (i = 1; i < arr.Length; i++)
			{
				//compare if small is greater than of any element of the array
				//assign that element in it.
				if (small > arr[i])
					small = arr[i];
			}

			//finally print the smallest elemeent of the integer array
			Console.WriteLine("Smallest element in array is : " + small);
		}
	}
}

Output

Enter array elements :
Element[1]: 12
Element[2]: 13
Element[3]: 10
Element[4]: 25
Element[5]: 8
Smallest element in array is : 8
