使用EntityFramework。Plus可以是一个选项:

dbContext.Employ.Where(e => e.Id == 1).Delete();

这里有更多的例子

您可以使用SingleOrDefault获取与您的条件匹配的单个对象，然后将其传递给EF表的Remove方法。

var itemToRemove = Context.Employ.SingleOrDefault(x => x.id == 1); //returns a single item.

if (itemToRemove != null) {
    Context.Employ.Remove(itemToRemove);
    Context.SaveChanges();
}

使用EntityFramework。Plus可以是一个选项:

dbContext.Employ.Where(e => e.Id == 1).Delete();

这里有更多的例子

你可以像这样简单地做

   public ActionResult Delete(int? id)
    {
        using (var db = new RegistrationEntities())
        {
            Models.RegisterTable Obj = new Models.RegisterTable();
            Registration.DAL.RegisterDbTable personalDetail = db.RegisterDbTable.Find(id);
            if (personalDetail == null)
            {
                return HttpNotFound();
            }
            else
            {
                Obj.UserID = personalDetail.UserID;
                Obj.FirstName = personalDetail.FName;
                Obj.LastName = personalDetail.LName;
                Obj.City = personalDetail.City;

            }
            return View(Obj);
        }
    }


    [HttpPost, ActionName("Delete")]

    public ActionResult DeleteConfirmed(int? id)
    {
        using (var db = new RegistrationEntities())
        {
            Registration.DAL.RegisterDbTable personalDetail = db.RegisterDbTable.Find(id);
            db.RegisterDbTable.Remove(personalDetail);
            db.SaveChanges();
            return RedirectToAction("where u want it to redirect");
        }
    }

模型

 public class RegisterTable
{

    public int UserID
    { get; set; }


    public string FirstName
    { get; set; }


    public string LastName
    { get; set; }


    public string Password
    { get; set; }


    public string City
    { get; set; }

} 

从视图中调用它

 <table class="table">
    <tr>
        <th>
            FirstName
        </th>
        <th>
            LastName
        </th>

        <th>
            City
        </th>
        <th></th>
    </tr>

    @foreach (var item in Model)
    {
        <tr>
            <td> @item.FirstName </td>
            <td> @item.LastName </td>
            <td> @item.City</td>
            <td>
                <a href="@Url.Action("Edit", "Registeration", new { id = item.UserID })">Edit</a> |
                <a href="@Url.Action("Details", "Registeration", new { id = item.UserID })">Details</a> |
                <a href="@Url.Action("Delete", "Registeration", new { id = item.UserID })">Delete</a>

            </td>
        </tr>

    }

</table>

我希望这对你来说很容易理解

Employer employer = context.Employers.First(x => x.EmployerId == 1);

context.Customers.DeleteObject(employer);
context.SaveChanges();

  var stud = (from s1 in entities.Students
            where s1.ID== student.ID
            select s1).SingleOrDefault();

  //Delete it from memory
  entities.DeleteObject(stud);
  //Save to database
  entities.SaveChanges();
