Question

我有此型号的清单：型号1

public class Model1//: IConvertible
{
    public int p1 { get; set; }

    public string p2{ get; set; }
}

我正在尝试从另一个表进行linq查询，以使用 Model1

的列表获取数据

List<Model1> lList = GetModel();
var test = Model2.Where(p => lList .Any(l => p.p1== l.p1 && p.p2== l.p2)).ToList();

我想念什么？

Answer 1

我将Lin和p1 + p2连接起来

<form class="subscription__form">
  <div class="form__email-input">

  </button>
</form>

然后在另一个查询中使用此列表是：

   var stringKeys = lList.Select((e, i) => lList[i].p1.ToString() + "_" + lList[i].p2).ToList();

Linq在哪里用型号清单关闭
