如何在WebApi中路由具有相同参数的两个get方法？

Question

在我的ApiController中，我有一个GET方法正在从数据库返回一些数据。

现在，我必须通过添加一个更多GET方法来扩大该控制器，该方法将从同一数据库返回数据，但是以另一种方式格式化，因此参数[[传递给该方法的参数将是相同的]与从第一个开始。

我正在尝试执行以下操作：

Public Class CshController
    Inherits ApiController

    Public Function GetValoriCsh(ByVal npv As String, ByVal nc As String) As IEnumerable(Of Cshlvl)
        Dim csh As Cshlvl = New Cshlvl
        Return csh.ValoreCsh(npv, nc)
    End Function

    Public Function GetOperazioni(ByVal npv As String, ByVal nc As String) As IEnumerable(Of OperazioniCsh)
        Dim operazioni As OperazioniCsh = New OperazioniCsh
        Return operazioni.OperazioniCsh(npv, nc)
    End Function


End Class

所以问题来了，api失败了，因为有两种方法需要相同的参数，所以它不知道如何选择我要使用的方法。 
实际上，我是通过以下URL api / csh /调用以下api的，是否可以通过某种方式调用api / csh /从GetValoriCsh获取数据，就像通过调用api / csh / operazioni /这样的数据来获取数据一样来自GetOperazioni吗？
我的WebApiConfig
Public Module WebApiConfig
    Public Sub Register(ByVal config As HttpConfiguration)
        ' Servizi e configurazione dell'API Web

        ' Route dell'API Web
        config.MapHttpAttributeRoutes()

        config.Routes.MapHttpRoute(
            name:="DefaultApi",
            routeTemplate:="api/{controller}/{id}",
            defaults:=New With {.id = RouteParameter.Optional}
        )

    End Sub
End Module

我尝试在GetOperazioni上方添加<Route("api/csh/op")>，但没有效果。

如果使用属性路由，则全部或全部。

<RoutePrefix("api/csh")>
Public Class CshController
    Inherits ApiController

    'GET api/csh
    <HttpGet()>
    <Route("")>
    Public Function GetValoriCsh(ByVal npv As String, ByVal nc As String) As IEnumerable(Of Cshlvl)
        Dim csh As Cshlvl = New Cshlvl
        Return csh.ValoreCsh(npv, nc)
    End Function

    'GET api/csh/op
    <HttpGet()>
    <Route("op")>
    Public Function GetOperazioni(ByVal npv As String, ByVal nc As String) As IEnumerable(Of OperazioniCsh)
        Dim operazioni As OperazioniCsh = New OperazioniCsh
        Return operazioni.OperazioniCsh(npv, nc)
    End Function
End Class
