16 mvc中的模糊查询和精确查询：
var talk = dbTalk.talk.Where(m => m.name.IndexOf(keyWord)>=0);//模糊查询
dbTalk.talk.Where(m => m.name.Equals(keyWord) == true);//精确查询
应用：
在控制器中的Action：
public ActionResult search()
{
string keyWord = Request.Form["keyWord"];
var talk = dbTalk.talk.Where(m => m.name.IndexOf(keyWord)>=0);//dbTalk.talk.Where(m => m.name.Equals(keyWord) == true);//
if (talk == null)
{ ViewData["error"] = "未找到相关信息！"; }
else
{ ViewData["error"] = "Yes！";}
ViewData.Model = talk; //视图页面数据
return View();
}
view中代码：
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<%@ Import Namespace="MvcApplication1.Models" %>//引入models
<% foreach (talk item in (IEnumerable)ViewData.Model)//转换为你想要的类型（ViewData.Model为控制器中传过来的数据）
{ %>
