LINQ 检查列表中是否存在 ID

Question

I am using LINQ Entity framework. I have a SQL table and I want to get all the items in the table that have an ID that exist in a List

Is this possible with LINQ?

Answer 1

对的，这是可能的。

(from item in yourContext.YourTable where yourList.Contains(item.ID) select item).ToList();

Answer 2

为此，您可以用Contains其转换成SQL IN ：

context.SomeTable.Where(r => someListOfId.Contains(r.ID));
