Using Html.BeginForm with querystring

Question

My url looks like this:

customer/login?ReturnUrl=home

In the login view, I have used this pattern of code which works fine.

Answer 1

To create a RouteValueDictionary from the querystring:

RouteValueDictionary queryStringDictionary = new RouteValueDictionary(Request.QueryString.AllKeys.ToDictionary(key => key, key => (object)Request.QueryString[key]));

Then you can use it with Html.BeginForm:

Html.BeginForm(null, null, queryStringDictionary, FormMethod.Post, new Dictionary { { "autocomplete", "off" } })
