VB.NET - Alternative to Array.Contains?
原标题:VB.NET - Alternative to Array.Contains?

此前,我在“NET Framework 3.5”上使用了这个词,并做了以下工作:

    If (New String() {"ER", "PM", "EM", "OC"}).Contains(Session("Position")) Then
         Some codes
    End If

现在,我正在实施一项与2.0网相联的项目,而上述准则并不奏效。

 Contains  is not a member of  System.Array .

我如何能够在不从2.0向3.0迁移的情况下实现上述准则? 任何替代品?

最佳回答

你们必须重新制定你们的法典。

If (Array.IndexOf(New String() {"ER", "PM", "EM", "OC"}), Session("Position")>-1) Then
         Some codes
End If

收集的初始编制者取决于汇编者,但并非目标框架,因此这项工作应当进行。

Edit:固定错误方法/条件。 我在进行这项工作时,与泄露的汇合在一起,这并不意味着在我证实其工作之前将其张贴。

问题回答

You can achieve this with Exists or Find

If Array.Exists(New String() {"ER", "PM", "EM", "OC"}, AddressOf FindExistance) Then
     Some codes   
End If



Private Function FindExistance(ByVal s As String) As Boolean
    If String.Equals(s, Session("Position")) Then
        Return True
    Else
        Return False
    End If
End Function
