ASP.NET：KeyValuePair之自定义用法

今天自己写了一个KeyValue类，主要是封装KeyValuePair，简化KeyValuePair的初始化和赋值方法，用起来更简单些：）

 1 public class KeyValue
 2 {
 3     /// <summary>
 4     /// 内部键值对象
 5     /// </summary>
 6     private KeyValuePair<object, object> obj = new KeyValuePair<object, object>();
 7 
 8     /// <summary>
 9     /// 返回数据
10     /// </summary>
11     public Object Data { get; set; }
12 
13     /// <summary>
14     /// 键
15     /// </summary>
16     public Object Key
17     {
18         get { return obj.Key; }
19         set { obj = new KeyValuePair<object, object>(value, obj.Value); }
20     }
21 
22     /// <summary>
23     /// 值
24     /// </summary>
25     public Object Value
26     {
27         get { return obj.Value; }
28         set { obj = new KeyValuePair<object, object>(obj.Key, value); }
29     }
30 
31     /// <summary>
32     /// 设置键值
33     /// </summary>
34     /// <param name="key"></param>
35     /// <param name="value"></param>
36     public void SetKeyValue(Object key, Object value) { obj = new KeyValuePair<object, object>(key, value); }
37     public void SetKeyValue(Object key, Object value, Object data)
38     {
39         obj = new KeyValuePair<object, object>(key, value);
40         this.Data = data;
41     }
42 
43     /// <summary>
44     /// 初始化键值对象
45     /// </summary>
46     /// <param name="key"></param>
47     /// <param name="value"></param>
48     public KeyValue(object key, object value) { SetKeyValue(key, value); }
49     public KeyValue(object key, object value, object data) { SetKeyValue(key, value, data); }
50 
51 }

用法示例：

　　KeyValue kv = new KeyValue("Hello", "World");
　　KeyValue kv1 = new KeyValue("Hello", "World", kv);
　　kv1.Key = "Hello World Key!";
　　kv1.Value = "Hello World Value!";
　　kv1.Data = kv;
　　kv1.SetKeyValue("Hello", "World");
　　kv1.SetKeyValue("Hello", "World", kv);

结合List，用起来简捷方便，易于扩展，以此为作键值基础，下一个示例将使用这个KeyValue来简化代码。
