parsedFunc2

Type: System.Func(T2, TResult)
Lambda executed on successful parsing of T2.

parsedFunc3

Type: System.Func(T3, TResult)
Lambda executed on successful parsing of T3.

notParsedFunc

Type: System.Func(IEnumerable(Error), TResult)
Lambda executed on failed parsing.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ParserResult(Object). When you use instance method syntax to call this method, omit the first parameter.
