Compare and contrast the Contains method and the IndexOf methods of determining whether a string contains a specific sequence of characters.
What will be an ideal response?
Both methods perform a case-sensitive search. The Contains method returns the Boolean value True when the substring is contained anywhere in the string; otherwise, it returns the Boolean value False. The IndexOf method returns in integer: either -1 or a number that is greater than or equal to 0. The -1 indicates that the substring is not contained in the string. A number other than -1 is the character index of the subString's starting position in the string.
