How to extract key/values from FormCollection in ASP.NET MVC?

To avoid you from having to chase for the same information: here’s how you extract key / value pairs from the FormCollection that comes as an argument in an ASP.NET MVC action method:

public ActionResult Create(FormCollection formCollection)
{
  foreach (var key in formCollection.AllKeys)
  {
    var value = formCollection[key]; // etc. 
  }

  foreach (var key in formCollection.Keys)
  { 
     var value = formCollection[key.ToString()]; // etc.
  }
}

Also, a final tip: If you find that the formCollection does not contain the key/value pairs you expected, check that

• Your controls reside within the correct form (you can have more than one)
• Your controls have names (just having an id is not returning values in the formCollection)Hope this helps.
