Both methods will convert the input value to small letters.

The difference here is ToLower is depending on current culture(ex: en-US) i.e ToLower method return a copy of this String object converted to lowercase using the casing rules of the specified culture. some time this culture dependency will result in invalid results.

Ex: For alphabhet (i) dot is removed. You can check this link for more details.

ToLowerInvariant Method will return a copy of this String object converted to lowercase using the casing rules of the invariant culture. ie. this method will convert characters to lowercase without culture dependency.
