通過WebServices使用字典

我試圖通過WebServices傳遞字典。但它不可序列化。所以我寫了自己的類，使得它可序列化：通過WebServices使用字典

using System; 
using System.Net; 
using System.Windows; 
using System.Collections.Generic; 
using System.Xml.Serialization; 
using System.Xml; 
using System.Xml.Schema; 

namespace Platform 
{ 
    public class SaDictionary<TKey, TValue> : Dictionary<TKey, TValue>, 
               IXmlSerializable 
    { 
     #region Constructors 
     public SaDictionary() : base() { } 

     public SaDictionary(IDictionary<TKey, TValue> dictionary) 
      : base(dictionary) { } 

     public SaDictionary(IEqualityComparer<TKey> comparer) 
      : base(comparer) { } 

     public SaDictionary(int capacity) 
      : base(capacity) { } 

     public SaDictionary(IDictionary<TKey, TValue> dictionary, 
          IEqualityComparer<TKey> comparer) 
      : base(dictionary, comparer) { } 

     public SaDictionary(int capacity, IEqualityComparer<TKey> comparer) 
      : base(capacity, comparer) { } 

     //protected SaDictionary(SerializationInfo info, 
     //      StreamingContext context) 
     // : base(info, context) 
     //{ 
     //} 
     #endregion 

     public XmlSchema GetSchema() 
     { 
      return null; 
     } 

     public void ReadXml(XmlReader reader) 
     { 
      XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); 
      XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); 
      bool wasEmpty = reader.IsEmptyElement; 
      reader.Read(); 

      if (wasEmpty) 
       return; 

      while (reader.NodeType != XmlNodeType.EndElement) 
      { 
       reader.ReadStartElement("item"); 
       reader.ReadStartElement("key"); 
       TKey key = (TKey)keySerializer.Deserialize(reader); 
       reader.ReadEndElement(); //key 

       reader.ReadStartElement("value"); 
       TValue value = (TValue)valueSerializer.Deserialize(reader); 
       reader.ReadEndElement(); //value 
       this.Add(key, value); 

       reader.ReadEndElement(); //item 
       // reader.MoveToContent(); 
      } 
      reader.ReadEndElement(); 
     } 

     public void WriteXml(XmlWriter writer) 
     { 
      XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); 

      XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); 
      foreach (TKey key in this.Keys) 
      { 
       writer.WriteStartElement("item"); 
       writer.WriteStartElement("key"); 
       keySerializer.Serialize(writer, key); 
       writer.WriteEndElement(); //key 
       writer.WriteStartElement("value"); 
       TValue value = this[key]; 
       valueSerializer.Serialize(writer, value); 
       writer.WriteEndElement(); //value 
       writer.WriteEndElement(); //item 
      } 
     } 
    } 
}

但是我得到一個ArrayOfXElement回來。有沒有辦法將它轉換回字典？ greets

如果您使用Visual Studio生成服務代理，那麼通過按「高級」按鈕，您將看到更改生成數據類型的選項。例如，您可以將集合類型映射到通用列表或可觀察集合，對於字典您可以基本告訴它映射到各種數據類型。

這應該會幫助你。

喜THX爲ansere但我仍然有一些問題：這樣做現在：服務提述─>新的服務參考 - > choose->高級我得到一個菜單，在這裏我可以映射字典列表或數組。但我想得到一個字典... 我得到了一個不可序列化的錯誤，所以我寫了上面的類，但現在我得到了arrayofxelement – Umit 2010-06-02 08:30:52
