Syntax

C#

public static TResult MapResult<T1, T2, TResult>(
	this ParserResult<Object> result,

	Func<T2, TResult> parsedFunc2,
	Func<IEnumerable<Error>, TResult> notParsedFunc
)

VB

<ExtensionAttribute>

Parameters

 

result

Type: CommandLine.ParserResult(Object)
The result in verb scenario.

parsedFunc1

Type: System.Func(T1, TResult)
Lambda executed on successful parsing of T1.

parsedFunc2

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

notParsedFunc

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

Type Parameters

First verb type.

T2

Second verb type.

TResult

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(Object). When you use instance method syntax to call this method, omit the first parameter.
