Url.Action参数? [英] Url.Action parameters?
问题描述
在列出的控制器我有,
公众的ActionResult GetByList(字符串名称,字符串触点)
{
VAR NameCollection = Service.GetByName(名);
VAR ContactCollection = Service.GetByContact(接触);
返回查看(新ListViewModel(NameCollection,ContactCollection));
}
在ASPX页面我打电话,
< A HREF =<%:Url.Action(GetByList,上市,新的{名称=约翰},新{触点=卡尔加里,温哥华})%GT;><跨度>人与LT; / SPAN>< / A>
我在ASPX code的一个问题...我可以拉记录的名字John。但是当我给触点=卡尔加里,温哥华,网页去错误。
我如何可以调用Url.Action两个参数。我试过以下,但看上去是错了。
< A HREF =<%:Url.Action(GetByList,上市,新的{名称=约翰,触点=卡尔加里,温哥华} )%GT;><跨度>人与LT; / SPAN>< / A>
下面是正确的过载(在你的榜样你缺少结束}
到 routeValues
匿名对象,以便您的code会抛出异常):
< A HREF =<%:Url.Action(GetByList,上市,新的{名称=约翰,触点=卡尔加里,温哥华} )%>中与GT;
<跨度>人与LT; / SPAN>
&所述; / A>
假设你使用的是默认路由这应该生成以下标记:
< A HREF =/上市/ GetByList名称=约翰&放大器;放大器;触点=卡尔加里%2C%20vancouver>
<跨度>人与LT; / SPAN>
&所述; / A>
这将成功地调用传递两个参数 GetByList
控制器动作:
公众的ActionResult GetByList(字符串名称,字符串触点)
{
...
}
In listing controller I have,
public ActionResult GetByList(string name, string contact)
{
var NameCollection = Service.GetByName(name);
var ContactCollection = Service.GetByContact(contact);
return View(new ListViewModel(NameCollection ,ContactCollection));
}
In ASPX page I call,
<a href="<%:Url.Action("GetByList","Listing" , new {name= "John"} , new {contact="calgary, vancouver"})%>"><span>People</span></a>
I have a problem in the ASPX code... I can pull the records for the name john. but when I give the contact="calgary, vancouver", the webpage goes to error.
How can I call two parameters in the Url.Action. I tried the below but that seems wrong too.
<a href="<%:Url.Action("GetByList","Listing" , new {name= "John" , contact= " calgary, vancouver" })%>"><span>People</span></a>
The following is the correct overload (in your example you are missing a closing }
to the routeValues
anonymous object so your code will throw an exception):
<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
<span>People</span>
</a>
Assuming you are using the default routes this should generate the following markup:
<a href="/Listing/GetByList?name=John&contact=calgary%2C%20vancouver">
<span>People</span>
</a>
which will successfully invoke the GetByList
controller action passing the two parameters:
public ActionResult GetByList(string name, string contact)
{
...
}
