        Array.Sort(a);
```

        Console.WriteLine("Sorted Array : ");

```
        for (int i = 0; i < x; i++)
```
```
        {
```

            Console.WriteLine("{0}", a[i]);

```
        }
```

        Console.WriteLine("Enter the Element to be Searched : ");

```
        string s3 = Console.ReadLine();
```
```
        int x2 = Int32.Parse(s3);
```

        int x3 = Array.BinarySearch(a, (Object)x2);

        Console.WriteLine("BinarySearch: " + x3);

        Console.WriteLine("Element {0} is {1}", x3, a[x3]);

```
        Console.Read();
```
```
    }
```
```
}
```

Here is the output of the C# Program:

Enter Number of Elements you Want to Hold in the Array ? 5
Enter Array Elements : 
2
3
1
4
5
Sorted Array :
1
2
3
4
5
Enter the Element to be Searched : 4
Binary Search : 3
Element 3 is 4
