用LINQ做一个IN语句

如何使用LINQ创建IN语句？

我有什么

    var t = from i in emails
            where i.Credencials_Id == agenciaid
            select new
            {
                i.Alias,
                i.Name,
                i.Description,
                i.Comentas,
                i.DateHour,
                i.Imovel_Id,
                i.Email,
                i.EmailCaptador
            };

我想要的东西（像这样的东西）

    var t = from i in emails
            where i.Credencials_Id IN (agenciaid)
            select new
            {
                i.Alias,
                i.Name,
                i.Description,
                i.Comentas,
                i.DateHour,
                i.Imovel_Id,
                i.Email,
                i.EmailCaptador
            };

int imovel = Convert.ToInt32(t.First().Imovel_Id);

Answer 1

当您使用LINQ to Objects时，您可以使用它：

from i in emails
where agenciaid.Contains(i.Credencials_Id)
select new
{
    i.Alias,
    i.Name,
    i.Description,
    i.Comentas,
    i.DateHour,
    i.Imovel_Id,
    i.Email,
    i.EmailCaptador
};
