将2d数组传递给vb.net中的wcf服务

Question

我试图将2d数组传递给wcf服务以连接到数据库并将2d数组返回到客户端以将数据放入列表视图中但引发错误：不支持2D数组

Function retreive(ByRef rows As Integer, ByRef colunms As Short, ByRef resarray(,) As String, ByVal identifier As Short) As Short Implements IService1.Retreive
    If (identifier = 0) Then
        Dim obj As New clsNews

        Return 0
    End If
