tuple元组：

赋值

List
     
      
       > cc = new List
       
        
         >()            {                new Tuple
         
          ("满减5", 1),                new Tuple
          
           ("满减2", 2), new Tuple
           
            ("满减5", 3), new Tuple
            
             ("满减1", 4) };
            
           
          
         
        
       
      
     

 取值

1  foreach (var item in cc)2             {3                  string ite = item.Item1;4                 int ctNum = item.Item2;5             }

 说明：可以当一个简单的类来用

list.ForEach的用法

1     cac.ForEach(delegate(cfg_AttributeChild ac)//list.ForEach的用法 2                 { 3                     Attributec a = new Attributec(); 4                     a.ID = Convert.ToInt32(ac.ID); 5                     a.msg = ac.Name; 6                     a.url = ac.Url; 7                     a.color = ac.Color; 8                     abc.Add(a); 9 10                 });
