推荐答案
错误信息是。 ..什么？
我猜你作为字符串提供的一些值应该是不同的类型（例如数字，DateTime）。因此，在添加参数时转换它们，例如
And the error message is ... what?
I guess that some of the values which you provide as strings ought to be different types (e.g. numbers, DateTime). Hence convert them when you add the parameters, e.g.
command.Parameters.AddWithValue("Mincharge", Convert.ToDouble(Mincharge.Text));
