The comma character after the command is compulsory as are all three parameters and the commas separating them.
Parameters:
SearchFor: The string to search for within the original string
OriginalString: The string to search
StringComparison: A string representing a member of the StringComparison enumeration:
SearchFor and OriginalString parameters are compulsory, the StringComparison parameter is optional. If provided, the value must be one of the following:
CurrentCulture |
Compare strings using culture-sensitive sort rules and the current culture.

It is good practice to include the quotation marks in any case, so that it reduces the risk of error when writing scripts.If the string contains no instances of the SearchFor value are located in the original string -1 will be returned.
