1、在主界面Index.cshtml添加“添加”的链接

 <tr>
                <td colspan="4"> @Html.ActionLink("添加", "Add", "Home") @Html.ActionLink("返回", "Index", "Home")</td>           
  </tr>

2、HomeController

2.1显示添加

[HttpGet]
 public ActionResult Add()
  {
            return View();
}

2.2执行添加

[HttpPost]
public ActionResult Add1()
{
            try
            {
                //DbEntityEntry<BlogUser> entry = db.Entry<BlogUser>(blogUser);
                BlogUser user = new BlogUser();          
                user.Id = int.Parse(Request["id"]);
                user.Name = Request["name"];
                user.State =bool.Parse(Request["state"]);

                ViewData.Model = user;
                //db.BlogUser.Attach(user);
                db.BlogUser.Add(user);
                db.SaveChanges();
                return RedirectToAction("Index", "Home");
                

            }
            catch (Exception ex)
            {

                return Content("添加失败," + ex.Message);
            }
 }

3、Add.cshtml

@using (Html.BeginForm("Add1", "Home", FormMethod.Post))
        {
        <table id="tbList">
            <tr>
                <td colspan="2">添加</td>
            </tr>
            <tr>
                <td>账号：</td>
                <td><input type="text" id="id" name="id" /></td>
            </tr>
            <tr>
                <td>姓名：</td>
                <td><input type="text" id="name" name="name" /></td>
            </tr>
            <tr>
                <td>状态：</td>
                <td><input type="text" id="state" name="state" /></td>
            </tr>
            <tr>
                <td colspan="2"><input type="submit" value="确认添加" />@Html.ActionLink("返回", "Index", "Home")</td>

            </tr>
        </table>
        }

其中name很关键，在controller中通过name来用request获取输入的值
布局代码

<title>添加</title>
    <style type="text/css">
        #tbList {
            border: 1px solid #0094ff;
            width: 400px;
            margin: 10px auto;
            border-collapse: collapse;
        }

            #tbList th, td {
                border: 1px solid #0094ff;
                padding: 10px;
            }
    </style>

结果
