推荐答案

，假设实体==实体
该模型与他的使用"相关联
并且您要删除
的记录 ID = 1的记录"表
您可以使用

assuming that the entity == Entities
the model is linked with his "using"
and you want to delete a record of the
"Record" table with id = 1
you can use

using (Entities entitiesContext = new Entities())
    {
        var e = from x in entitiesContext.Records
                where x.Id = 1
                select x;
        Record record = e.FirstOrDefault();
        entitiesContext.Records.DeleteObject(record);
        entitiesContext.SaveChanges();
    }

如果记录不仅是一个记录而且很多，那么必须使用带有DeleteObject方法的foreach循环

在循环之外，您可以保存更改

if the record is not only one but a lot, you have to use a foreach loop with the DeleteObject method

and outside of the loop you can save changes
