The PromptChar property represents the prompt character that is used by the ToDisplayString and ToString methods to represent the current state of the formatted input string. A prompt character is placed in editable positions that have not yet been assigned an input value. Some versions of the ToString method also depend on the value of the IncludePrompt property.
