我正在研究XML序列化,並且由於我使用了大量的字典,因此我想將它們序列化。我找到了以下解決方案(我爲此感到非常自豪!:))。控制字典的XML序列<K, T>
[XmlInclude(typeof(Foo))]
public class XmlDictionary<TKey, TValue>
{
/// <summary>
/// Key/value pair.
/// </summary>
public struct DictionaryItem
{
/// <summary>
/// Dictionary item key.
/// </summary>
public TKey Key;
/// <summary>
/// Dictionary item value.
/// </summary>
public TValue Value;
}
/// <summary>
/// Dictionary items.
/// </summary>
public DictionaryItem[] Items
{
get {
List<DictionaryItem> items = new List<DictionaryItem>(ItemsDictionary.Count);
foreach (KeyValuePair<TKey, TValue> pair in ItemsDictionary) {
DictionaryItem item;
item.Key = pair.Key;
item.Value = pair.Value;
items.Add(item);
}
return (items.ToArray());
}
set {
ItemsDictionary = new Dictionary<TKey,TValue>();
foreach (DictionaryItem item in value)
ItemsDictionary.Add(item.Key, item.Value);
}
}
/// <summary>
/// Indexer base on dictionary key.
/// </summary>
/// <param name="key"></param>
/// <returns></returns>
public TValue this[TKey key]
{
get {
return (ItemsDictionary[key]);
}
set {
Debug.Assert(value != null);
ItemsDictionary[key] = value;
}
}
/// <summary>
/// Delegate for get key from a dictionary value.
/// </summary>
/// <param name="value"></param>
/// <returns></returns>
public delegate TKey GetItemKeyDelegate(TValue value);
/// <summary>
/// Add a range of values automatically determining the associated keys.
/// </summary>
/// <param name="values"></param>
/// <param name="keygen"></param>
public void AddRange(IEnumerable<TValue> values, GetItemKeyDelegate keygen)
{
foreach (TValue v in values)
ItemsDictionary.Add(keygen(v), v);
}
/// <summary>
/// Items dictionary.
/// </summary>
[XmlIgnore]
public Dictionary<TKey, TValue> ItemsDictionary = new Dictionary<TKey,TValue>();
}
從此類派生的類以下面的方式進行序列化:
<FooDictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Items>
<DictionaryItemOfInt32Foo>
<Key/>
<Value/>
</DictionaryItemOfInt32XmlProcess>
<Items>
這給我一個很好的解決方案,但是:
- 我如何控制的名稱元素DictionaryItemOfInt32Foo
- 如果我定義了
Dictionary<FooInt32, Int32>
和I,會發生什麼情況有類Foo
和FooInt32
? - 可以優化上面的類嗎?
非常感謝!
如果指定任意名稱,則不能反序列化元素。 – Luca 2010-05-15 11:44:13
