实现自定义Hashtable (.net)

需要两个类

1．typeFiles.cs

C#

using System; namespace Model {     /// <summary>     /// typeFiles 的摘要说明。     /// </summary>     public class typeFiles     {         private object _Fkey;         private object _Fvalue1;         private object _Fvalue2;         public object Fkey         {             get             {                 return _Fkey;             }             set             {                 _Fkey = value;             }         }         public object Fvalue1         {             get             {                 return _Fvalue1;             }             set             {                 _Fvalue1 = value;             }         }         public object Fvalue2         {             get             {                 return _Fvalue2;             }             set             {                 _Fvalue2 = value;             }         }     } }

  
2．WEHash.cs (Hashtable 类, 与Arraylist结合)

C#

using System; using System.Collections; namespace Command {     /// <summary>     /// WEHash 的摘要说明。     /// </summary>     public class WEHash     {         private ArrayList alist = new ArrayList();         public WEHash()         {             //             // TODO: 在此处添加构造函数逻辑             //         }         public void Add(object key,object value,object valType)         {             Model.typeFiles cmt=new Model.typeFiles();             cmt.Fkey = key;             cmt.Fvalue1 = value;             cmt.Fvalue2 = valType;             alist.Add (cmt);         }         public ArrayList HashItems         {             get             {                 return alist;             }             set             {                 alist = value;             }         }         public bool hasContaint(object key)         {             foreach(object itm in alist)             {                 Model.typeFiles cmt = (Model.typeFiles)itm;                 if (cmt.Fkey.ToString() == key.ToString())                     return true;             }             return false;         }     } }

typeFiles.cs 里可以多定义几个构造函数 (这样Hash.Add(项才可以多))

使用方法:

Command.WEHash cw=new WEHash();
cw.Add("keyName1","value1","value2");
cw.Add("keyName2","value1","value2"); 
cw.Add("keyName3","value1","value2");

然后再把 cw.HashItems 传给要操作的方即可.

要使.Add添加个项更多，就要使得 typeFiles.cs 构造多几个，然后再修改

 public void Add(object key,object value,object valType)
{ 
      Model.typeFiles cmt=new Model.typeFiles(); 
      cmt.Fkey = key; 
      cmt.Fvalue1 = value; 
      cmt.Fvalue2 = valType; 
      ....其余的cmt项.
      alist.Add (cmt);
}
