HttpContext.Request.QueryString does not support passing arrays as parameters

Currently unable to send an array of items on a query string. Calling _.Get.Url("/endpoint").QueryString("relatedCustomerIds", 123).QueryString("relatedCustomerIds", 456) causes only relatedCustomerIds=456 to be appended to the resultant url. This problem could be solved by allowing multiple values per-key, or simply not manipulating the url to split query parameters into the HttpContext.Request.QueryString dictionary.

I ended up getting it to work by using:

_.Get.Url("/endpoint")
  .QueryString("relatedCustomerIds[0]", 123)
  .QueryString("relatedCustomerIds[1]", 456)

We are currently investigating a way to add lists like these to the query string without specifying the array indices using HttpContext.Request.QueryString.Create(IEnumerable<KeyValuePair<string,StringValues>>);
