Question

我在这里有一些我已经帮助修改的代码，但是这段代码中有一部分可以更简化（ if orelse 语句）。我知道它与集合类或数组有关，但我对如何更改它感到困惑。任何帮助将不胜感激。

Function GetLastName(ByVal accountName As String) As String

    Dim lastName As  
    Dim stringArray As Array = accountName.Split(" ")
    Dim lastIndex = stringArray.Length - 1  'lastIndex will serve as the UpperBound of the Array
    Dim lastElement = stringArray(lastIndex).ToUpper

    If ((lastElement.Equals("JR")) OrElse (lastElement.Equals("JR.")) _
    OrElse (lastElement.Equals("SR")) OrElse (lastElement.Equals("SR.")) _
    OrElse (lastElement.Equals("I")) OrElse (lastElement.Equals("II")) _
    OrElse (lastElement.Equals("III")) OrElse (lastElement.Equals("IV")) _
    OrElse (lastElement.Equals("M.D.")) OrElse (lastElement.Equals("M.D")) _
    OrElse (lastElement.Equals("PH.D.")) OrElse (lastElement.Equals("PHD.")) _
    OrElse (lastElement.Equals("PHARM.D")) OrElse (lastElement.Equals("M.B.A"))) Then

Answer 1

Dim titles As IList(Of String) = New List(Of String)()

titles.Add("JR")
titles.Add("JR.")
titles.Add("SR")
titles.Add("SR.")
' ....

Return titles.Contains(lastElement)
