我做了很多追踪和错误，找到了解决问题的方法。答案是SQL Server 2008 R2，我正在使用它，不支持命名参数。这就是错误的原因。

我必须更改我的代码，如下所示：

If cls.UserID = 0 Then
                        sql = "INSERT INTO Tabusers ("
                        sql &= " BenchID,"
                        sql &= " UserType,"
                        sql &= " UserName,"
                        sql &= " Password,"
                        sql &= " Status,"
                        sql &= " LastInTime,"
                        sql &= " LastOutTime"
                        sql &= ") VALUES ("
                        sql &= " ?,"
                        sql &= " ?,"
                        sql &= " ?,"
                        sql &= " ?,"
                        sql &= " ?,"
                        sql &= " ?,"
                        sql &= " ?"
                        sql &= " )"

然后它奏效了。谢谢大家的建议。
