Sequential Search in C#

Input -
1. one Array
2. one value to be searched

Algorithm
I am giving one simple example.

bool SequenceSearch(int[] arr, int svalue)

        {

            for (int index = 0; index < arr.Length - 1; index++)

            {

                if (arr[index] == svalue)

                {

                    return true;

                }

                else

                {

                    return false;

                }

            }

            return false;

        }

If 'svalue' is found in array then it will return true otherwise false.
