推荐答案

您的 SqlCommandBuilder 代码显示没有定义构造函数。这意味着只有默认的无参数构造函数。因此，您无法调用不存在的构造函数 new SqlCommandBuilder（da）。



这就是全部。就这么简单。

-SA

Your SqlCommandBuilder code shows that there is no constructor defined. It means that there is only the default, parameterless constructor. Therefore, you cannot call the non-existing constructor new SqlCommandBuilder(da).

That's all. As simple as that.
