I'm trying to do a redirect to action with a querystring array:
string[] variantIds = new {
"test1",
"test2",
};
return RedirectToAction("SamplesOrderStep3", new { variantIds });
But this redirects to
sample-order-step3?variantIds=System.String%5B%5D
How do I get it to go to
sample-order-step3?variantIds=test1&variantIds=test2
Looks like you are unable to redirect directly using redirect to action - in the end I used a mixture or Url.Action and Redirect:
return Redirect($"{Url.Action("SamplesOrderStep3")}?variantIds={string.Join("&variantIds=", variantIds)}");
I believe this 'How do you link to an action that takes an array as a parameter (RedirectToAction and/or ActionLink)?' describes your situation, Lee Smith answer seems similar and useful.
I believe that it's better if you convert it to string with a separator
string variantIdsString = "test1,test2";
Or try to use a list of strings instead of an array.
