项目多次添加到列表中
[英]Items added to a list multiple times
问题描述
我正在尝试仅使用c＃建立一个药房项目。我编写了一个代码来诊断患者的疾病并为其打印合适的治疗药物，我想检查该药物是否已经在我的药房中（可用的药物是如果存在，则程序会将其传递给Selling方法，如果不存在，我想添加到列表中，以便稍后再订购，问题是每次运行代码时将多次添加该器官系统中所有疾病的所有药物

您想要的是检查列表以查看其是否已包含字符串。 这很容易做到：
// If the list of drugs to be ordered does not contain this drug name
if(!ToBeOrdered.Contains("DrugNameGoesHere")
{
// Then, add this drug name to the list.
ToBeOrdered.Add("DrugNameGoesHere");
}

这段代码太乱了。 用某种黑暗的魔法使这个项目有意义。 如果有列表，请使用linq仅获得唯一的名称。
list = list.GroupBy(x => x.DrugName).Select(x => x.First()).ToList();
如何根据列表中的项目数多次显示通知
