C# 实体框架LINQ Include-子实体

我正在从我的交易详情加载子实体

UserStarted

var result = (from A in context.Transactions.Include(_ => _.TransactionDetails.Select(us => us.UserStarted))
              select A).SingleOrDefault();

现在我想加载另一个实体，但我不知道如何加载。该实体类似于

UserStarted

，它是

UserEnded

，也来自TransactionDetails

var result = (from A in context.Transactions.Include(_ => _.TransactionDetails.Select(us => us.UserStarted))
              select A).SingleOrDefault();

非常感谢

您可以将多个include谓词链接在一起：

var result = context.Transactions
  .Include(transaction => transaction.TransactionDetails.Select(us => us.UserStarted))
  .Include(transaction => transaction.TransactionDetails.Select(us => us.UserEnded))
  .SingleOrDefault();

你也可以试试

 var result = (from A in context.Transactions.Include(_ => _.TransactionDetails.Select(us => new { UserStarted  = us.UserStarted, UserEnded = us.UserEnded }))
select A).SingleOrDefault();
