Controller ==> View
1.ViewBag
controller:
public ActionResult Index() { var students=new List<string>{ "Zhang", "Li", "Wang" }; ViewBag.students = students; return View(); }
View:
@foreach (var s in ViewBag.students) { <tr> <td> @s </td> </tr> }
2.ViewData
controller:
public ActionResult Index() { //var music = me.Album.ToList(); var students=new List<string>{ "Zhang", "Li", "Wang" }; ViewData["Students"] = students; return View(); }View:
@foreach (var s in (List<string>)ViewData["Students"])
{
<tr>
<td>
@s
</td>
</tr>
}

3.TempData
TempData可以在不同action中传递一次,而ViewData、ViewBag在跳转后就会变成null。下面是TempData的用法示例:
public ActionResult Index()
{
string students = "xsaf";
TempData["Students"] = students.ToString();
return View();
}
public ActionResult Page()
{
var students = TempData["Students"];
Response.Write(students);
return View();
}
利用“?”参数传值
ActionLink
View:
@Html.ActionLink("linkText", "actionName", "controllerName")
@Html.ActionLink("链接", "Index", "Home") 等于 <a href="Home/Index">链接</a>
@Html.ActionLink("linkText", "actionName", "controllerName", routeValues, htmlAttributes)
@Html.ActionLink("链接", "Index", "Login", new{ code=123 }, new{target="_blank"} )
controller:
public ActionResult Login(int code) {
int CCode=code; //直接获取到code的值为123.
return View();
}
