Int. Parse () is a class-tolerant transformation that converts a string of numeric content into an int type.
Throws a ArgumentNullException exception if the string is empty;
Throws a FormatException exception if the string content is not a number;
Throws a OverflowException exception if the string content represents a number that is outside the range represented by the int type;

Int. TryParse and Int. Parse is more similar, but it does not produce an exception, the conversion succeeds and returns True, and the conversion fails to return false. The last parameter is the output value, and if the conversion fails, the output value is 0
