c# - lambda 表达式

Question

我可以用 lambda 表达式简化这个语句吗？

var project = from a in accounts
              from ap in a.AccountProjects
              where ap.AccountProjectID == accountProjectId
              select ap;

Answer 1

var project = accounts.SelectMany(a => a.AccountProjects)
                      .Where(x => x.AccountProjectID == accountProjectId);

这是否真的更简单是个人喜好问题。
