Can I loop through a Collection.Request.Form?

Question

I have some checkboxes with a unique id. is it possible to find all the checkbox+uniquenum in a form collection?

something like -

foreach (var item in Collection.Request.Form["checkbox" + with UniqueIDNum])
{
    //code
}

Answer 1

No.

Instead, you can loop through all of the keys, and check whether they start with checkbox.

For example:

foreach(string key in Request.Form) {
    if (!key.StartsWith("checkbox")) continue;
    ...
}

The NameValueCollection enumerator returns keys as strings.
