项目多次添加到列表中
我正在尝试仅使用c＃构建一个药房项目 我写了一个代码来诊断患者的疾病并打印出合适的治疗药物，我想检查一下这种药是否已经在我的药房（可用的药物在另一个类别中定义） 如果它存在，那么程序会将它传递给sell方法，如果它不存在，我想添加到列表中，以便我可以稍后订购 问题是，每次运行代码时，它都会多次添加该器官系统中所有疾病的所有药物

你想要的是检查列表以查看它是否已包含字符串。这很容易完成：
// 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");
}
您可以在此处详细了解Contains：http://www.dotnetperls.com/list-contains

这段代码太乱了。用某种黑魔法来理解这个项目。 如果您有一个列表，请使用linq只获取唯一的名称。
list = list.GroupBy(x => x.DrugName).Select(x => x.First()).ToList();
