Passing Arrays to MVC Actions via AJAX: The Traditional Serialization Parameter
This article addresses common challenges when passing arrays from jQuery AJAX to ASP.NET MVC controller actions. When array parameters appear in URLs with bracket notation (e.g., arrayOfValues[]=491), the MVC model binder may fail to parse them correctly.
