This method compares the value parameter to the substring at the beginning of this string that is the same length as value, and returns a value that indicates whether they are equal. To be equal, value must be an empty string (String::Empty), must be a reference to this same instance, or must match the beginning of this instance.
This method performs a comparison using the specified casing and culture.
The following example determines whether a string occurs at the beginning of another string. The StartsWith method is called several times using case sensitivity, case insensitivity, and different cultures that influence the results of the search.
