view到controller:
1.view页面使用<form><input><textbox>等提交,各个提交的数据各自命名;
controller页面使用"FormCollection form"接收,用form["数据名"]使用数据;
  ex:
  view页面:
<form>
<input name="searchtype "/>
<input name="nowpage "/>
<input name="search "/>
</form>
  controller页面:
    public ActionResult Index(FormCollection form)
    {
string str1=form["searchtype  "];
string str2=form["nowpage "];
string str3=form["search"];
}

2.view页面使用<form><input><textbox>等提交,各个提交的数据各自命名;

    controller页面使用"数据类型数据名"形式直接接收并使用数据;
  ex:
   view页面:
<form>
<input name="searchtype "/>
<input name="nowpage "/>
<input name="search "/>
</form>
  controller页面:
                      public ActionResult Index (String searchtype, String nowpage,String search)

{
string str1=searchtype;
string str2=nowpage;
string str3=fsearch;
}

3.view页面使用<form><input><textbox>等提交,各个提交的数据各自命名;

    controller页面使用Request.Form["数据名"]形式直接接收并使用数据;
  ex:
   view页面:
<form>
<input name="searchtype "/>
<input name="nowpage "/>
<input name="search "/>
</form>
  controller页面:
                      public ActionResult Index ()

{
string str1=Request.Form["searchtype "];

string str2=Request.Form["nowpage "];

string str3=Request.Form["fsearch "];

}

4. model页面创建一个model
view页面引用此模型,并使用htmlhelper和lamdba表达式提交数据
controller页面接收model,并用model变量名.数据名形式使用数据;

ex:
model页面:

public class LogOnModel

{
public string User { get; set; }
}

   view页面:
   @model 项目名.Models.LogOnModel
  @using (Html.BeginForm()) {

@Html.LabelFor(m => m.UserName)
}

controller页面:
public ActionResult Index (LogOnModel model)

{
string str=model.UserName ;
}

controller到view:

1.controller使用ViewData存储数据

view页面读取相应viewdata

ex:

controller页面:

public ActionResult UsingViewData(){

ViewData["Title"] = " Using ViewData";

Dictionary<string, string> stackholder = new Dictionary<string, string>();

stackholder.Add("Client","Mr. Client");

stackholder.Add("Manager","Mr. Joy");

stackholder.Add("Team Leader","Mr.Toy");
