    public class ABC : Hashtable
    static class Program
    
        public static ABC  a= new ABC();
        static void Main(string[] args)
        
            var c = a["0"]; //自定义类中括号取值
        
    

 

        var t = Request.Form["sets"].ToString();
  public abstract class HttpRequest
    
        public abstract IFormCollection Form  get; set; 
    

    public interface IFormCollection : IEnumerable<KeyValuePair<string, StringValues>>, IEnumerable
    
  

        StringValues this[string key]  get; 

        int Count  get; 
     
        ICollection<string> Keys  get; 

        IFormFileCollection Files  get; 


        bool ContainsKey(string key);

      
        bool TryGetValue(string key, out StringValues value);
