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: }
