Answer 1

尝试链接像这样的选择

.Where(x => x.AdmissionNo == 15200).select (n => n.FirstName) 

获取名单。

Answer 2

我相信你需要这个，

InfowareEntities Infoware = new InfowareEntities();   
IEnumerable admn = Infoware.Admissions.Where(x => x.AdmissionNo == 1520002);
var arrayOfFirstNames = admn.select(n => n.FirstName).ToArray();

您还可以使用“ToList（）;”如果你想要名字列表..
