	this ParserResult<TSource> result,
	Func<TSource, TResult> parsedFunc,
	Func<IEnumerable<Error>, TResult> notParsedFunc
)

VB

<ExtensionAttribute>
Public Shared Function MapResult(Of TSource, TResult) ( 
	result As ParserResult(Of TSource),
	parsedFunc As Func(Of TSource, TResult),

) As TResult

	Func<IEnumerable<Error^>^, TResult>^ notParsedFunc
)

F#

[<ExtensionAttribute>]
static member MapResult : 
        result : ParserResult<'TSource> * 
        parsedFunc : Func<'TSource, 'TResult> * 
        notParsedFunc : Func<IEnumerable<Error>, 'TResult> -> 'TResult 

Parameters

 

result

Type: CommandLine.ParserResult(TSource)
An ParserResult(T) instance.

parsedFunc

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

notParsedFunc

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

Type Parameters

 

TSource

Type of the target instance built with parsed value.

TResult

The type of the new value.

Return Value

Type: TResult
The new value.

Usage Note

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