The Char.CompareTo() method in C# is used to compare this instance to a specified object or value type, and indicates whether this instance precedes, follows, or appears in the same position in the sort order as the specified object or value type.SyntaxFollowing is the syntax −public int CompareTo (char val); public int CompareTo (object val);Above, Val for the 1st syntax is a char object to compare, whereas for the 2nd syntax it is an object to compare this instance to or null.The return value is zero if the current instance has the same position in the sort order as Val. ...
