how to pass multiple key/value pairs in a single variable using query string?

Question

I have one requirement like passing multiple values in the query string in a single variable.

Id=(refine_1=cgid=womens&refine_2=c_refinementColor=Black&refine_3=price=(0..500))

Is it possible to accept value like above sample from the query string?if yes,please tel me how to achieve this?

You should URL encode it:

?id=(refine_1%3Dcgid%3Dwomens%26refine_2%3Dc_refinementColor%3DBlack%26refine_3%3Dprice%3D(0..500))

Now assuming that your controller action takes an id parameter:

public ActionResult SomeAction(string id)
{
    ...
}

the value of this parameter inside the action will be (refine_1=cgid=womens&refine_2=c_refinementColor=Black&refine_3=price=(0..500)).

You could bring this even a step further and write a custom model binder that will parse this value and bind it to a view model containing those properties that your controller action could take as parameter instead of a id string parameter.
