SqlParameter问题

[thisisdell]

    Public Function AjaxPage(currentpage As Integer, pagesize As Integer, sortfield As String, sortorder As String, model As Model.Article, procname As String) As DataSet
        Try
            Dim param As SqlParameter()
            param = {
                    New SqlParameter("@currentpage", SqlDbType.SmallInt),
                    New SqlParameter("@pagesize", SqlDbType.SmallInt),
                    New SqlParameter("@sortfield", SqlDbType.VarChar, 64),
                    New SqlParameter("@sortorder", SqlDbType.VarChar, 8),
                    New SqlParameter("@auditresults", SqlDbType.TinyInt),
                    New SqlParameter("@searchkey", SqlDbType.VarChar, 32)
                   }
            param(0).Value = Convert.ToInt16(currentpage)
            param(1).Value = Convert.ToInt16(pagesize)
            param(2).Value = sortfield
            param(3).Value = sortorder
            param(4).Value = Convert.ToInt16(model.AuditResults)
            param(5).Value = StringPlus.ClearChar(model.SearchKey)
            Dim ds As DataSet = DbHelperSql.RunProcToDataSet(procname, param)
            If DbHelperSql.JudjeDataset(ds) Then
                Return ds
            Else
                Return Nothing
            End If
        Catch ex As Exception
            Throw
        End Try
    End Function

当model.AuditResults=0时，存储过程接收到的值是null，而不是0。
参考https://msdn.microsoft.com/zh-cn/library/0881fz2y(v=vs.100).aspx的说明，修改后问题依旧。
请问诸位老师如何解决？多谢！

代码的参数顺序和存储过程的参数顺序一样吗

顺序一样，model.AuditResults大于0时，都没有问题，只是等于0时，显示null
