在webservice中传递Hashtable

webservice中不支持hashtable的数据类型，那么如何在webservice中传递hashtable呢？我们可以通过将hashtable转化为webservice中支持的数组的类型来进行传递，在调用的时候再转换成hashtable就可以了。

   1: [WebMethod]

   2:     public DictionaryEntry[] SetValue()

   3:     {

   4:         Hashtable sl = new Hashtable();

   5:         sl.Add("kiss", "me");

   6:         sl.Add("love", "you");

   7:         DictionaryEntry[] array = new DictionaryEntry[sl.Count];

   8:         sl.CopyTo(array, 0);

   9:         return array;

  10:     }

调用webservice中的方法

   1: using System;

   2: using System.Data;

   3: using System.Configuration;

   4: using System.Web;

   5: using System.Web.Security;

   6: using System.Web.UI;

   7: using System.Web.UI.WebControls;

   8: using System.Web.UI.WebControls.WebParts;

   9: using System.Web.UI.HtmlControls;

  10: using System.Collections;

  11: using SourceCode;

  12: using localhost;

  13: public partial class _Default : System.Web.UI.Page

  14: {

  15:     protected void Page_Load(object sender, EventArgs e)

  16:     {

  17:         if (!IsPostBack)

  18:         {

  19:             getHashTable();

  20:          }

  21:       }

  22:  

  23:     private void getHashTable()

  24:     {

  25:         Hashtable obj = new Hashtable();

  26:         localhost.WebService test = new localhost.WebService();

  27:         localhost.DictionaryEntry[] entries = (localhost.DictionaryEntry[])test.SetValue();

  28:         foreach (localhost.DictionaryEntry entry in entries)

  29:         {

  30:                obj.Add(entry.Key, entry.Value);

  31:         }

  32:         foreach (System.Collections.DictionaryEntry each in obj)

  33:         {

  34:             Response.Write(each.Key.ToString() + "=" + each.Value.ToString() + "<br/>");

  35:         }

  36:  

  37:     }

  38:     }
