In this program, You will learn how to find the second smallest element in an array in C#.

```
Array List is: 10 20 30 40 50 60 70 80 90 100
The second Smallest element is: 20
```

## Example: How to find the second smallest element in an array in C#.

```
using System;
public class Program
{
public static void Main(string[] args)
{
int i, j, temp;
int[] arr = new int[5];
Console.Write("Enter five numbers:");
for (i = 0; i < arr.Length; i++)
{
arr[i] = Convert.ToInt32(Console.ReadLine());
}
for (i = 0; i < 5; i++)
{
for (j = i + 1; j < 5; j++)
{
if (arr[i] > arr[j])
{
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}
Console.WriteLine("Second smallest element:" + arr[1]);
}
}
```

#### Output:

```
Enter five numbers:10
30
20
40
50
Second smallest element:20
```
