Question

我编写了一个C＃代码，它将函数（1-9）发送到微控制器，控制器将通过RS232（SERIAL PORT）将数据发送回我的计算机。我遇到的问题是我试图获取传入的数据并将其放入排序列表中。排序列表键将是日期/时间，值将是传入数据。我试图将sortedlist部分添加到我的代码中，但它没有成功。我得到的错误是：

错误CS1503参数2：无法从'int'转换为'serialreadwrite.SMCValues'

CS0162检测到无法访问的代码SMCData-

您正在尝试将整数值'j'分配给作为类的'SMCValues'。

从您的问题看来，您最初是在尝试验证您是否可以获得有效日期的排序列表，因此您可以暂时进行以下更改：

//SortedList<DateTime, SMCValues> mySL1 = new SortedList<DateTime, SMCValues>(); SortedList<DateTime, int> mySL1 = new SortedList<DateTime, int>();

你也需要改变你的foreach。

然后在您准备好之后，交换回原始声明，并确保在.Add语句中使用'SMCValues'

如何将我的传入数据放入排序列表？
