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:
//引入models
{ %>
