使用LINQ选择2个表

Question

我有这样的查询：

var q2 = from i in dbconnect.tblComplementContracts
                 join b in dbconnect.tblContracts on i.contractId equals  b.contractId
                where (i.complementDate.Value - GetTime()).TotalDays <= _permission
                select i;

我想访问“i”和“b”字段，例如我尝试“选择i，b”但是它不起作用我该怎么办？

您可以使用匿名类型：

var q2 = from i in dbconnect.tblComplementContracts
         join b in dbconnect.tblContracts on i.contractId equals  b.contractId
         where (i.complementDate.Value - GetTime()).TotalDays <= _permission
         select new { I = i, B = b};

foreach (var x in query)
{
    Console.WriteLine("complementDate:{0} contractId:{1}", 
        x.I.complementDate, x.B.contractId);
}
