如何选中复选框

Question

我在MVC中使用Checkbox我的CShtml是这样的：

List<registrationchk.Models.hobby> mylist1 = ViewBag.hobbies;

foreach (var h in mylist1)
{
                <tr>
                    <input type="checkbox" name="hobbies" value="@h.Hobbie" class="checkboxTwo" style="background-color:aliceblue" />@h.Hobbie

                </tr>
}

现在我想要在编辑模式下选中复选框列表。在Controller的编辑模式中我编写了这段代码：

public ActionResult Edit(int? id)

    {
        TestEntities db = new TestEntities();
        ViewBag.hobbies = db.hobbies.ToList();

        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Employee employee = db.Employees.Find(id);
        string[] times = (employee.hobbies).Split(',');
      //  string hobbies = collection["hobbies"];
       // collection["hobbies"] = string hobbies;

        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        foreach (var item in employee.hobbies)
        {

            if (item)
            {
                //append each checked records into StringBuilder
                sb.Append(item + ",");

            }


        }

我希望在编辑模式下检查复选框列表。

将您的复选框代码替换为以下代码。

@ Html.CheckBoxFor（h => h.Hobbie，new {@class =“checkboxTwo”}）
