In ASP.NET MVC 2, can I deserialize a querystring into an array using the default ModelBinder?
In ASP.NET MVC 2, you can use this URL and this controller method:
GET http://server/controller/get?id=5
public ActionResult Get(int id)
{
...
}
And the ModelBinder will convert the id=5
querystring to id = (in开发者_运维知识库t) 5
in the method parameter. However, this won't work:
GET http://server/controller/get?idlist=1,2,3,4,5
public ActionResult Get(int[] idlist)
{
...
}
idlist
will be null in the parameter. Although the parsing for this is pretty trivial, I was wondering if there is a way to either change the method signature or the querystring in order to make the default ModelBinder automatically deserialize arrays/collections?
With the default modelbinder, the url should be
http://server/controller/get?idlist=1&idlist=2&idlist=3&idlist=4&idlist=5
or
http://server/controller/get?idlist[]=1&idlist[]=2&idlist[]=3&idlist[]=4&idlist[]=5
If you really want to use idlist=1,2,3,4,5, you should have your own binder
This is a little late to the party but I wanted to do exactly the same thing.
You can pass the single string as {1,2} and it the binder will bind it to an array e.g
<input name="idlist" type="text" value="{163,162}">
Here's what I think:
public ActionResult Get(int id)
{
...
}
Should be used as
GET http://server/controller/get/5
And the idlist can be simply split by comma(,)
