调用webservices 返回值问题

Question

[WebMethod] 
public string[] Selectassname(string prefixText, int count) 
{ 
    List <string> results = new List <string>(count); 
    string sql = "select distinct top 10(assName) from Assign where assName like '" + prefixText + "%'"; 
    DataTable dt = new DataTable(); 
    SqlHelper.FillDataTable(sql, dt); 
    foreach (DataRow dr in dt.Rows) 
    { 
        if (dr["assName"].ToString() != "") 
        { 
              results.Add(dr["assName"].ToString()+" "); 
        } 
    } 
    return results.ToArray <string>(); 
} <?xml version="1.0" encoding="utf-8" ?> 
- <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/"> 
  <string>1 </string> 
  <string>1-1 </string> 
  <string>1-1-1 </string> 
  <string>1-1-2 </string> 
  <string>1-1-3 </string> 
  <string>1-1-4 </string> 
  <string>1-1-5 </string> 
  <string>1-2 </string> 
  <string>1-2-1 </string> 
  <string>1-2-2 </string> 
  </ArrayOfString> 直接浏览正常显示 页面调用显示结果
1 
0 
-1 
-2 
-3 
-4 
-5 
-1 
-2 
-3 就变成计算过后的值了， 
要怎么让他原封不动的返回

Answer 1

没发现这种问题。
[System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {    public WebService () {        //濡傛灉浣跨敤璁捐鐨勭粍浠讹紝璇峰彇娑堟敞閲婁互涓嬭 
        //InitializeComponent(); 
    }    [WebMethod]
    public string[] HelloWorld() {
        return new string[] { "1-2", "2-3" };
    }
    
}
<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
        <Services>
            <asp:ServiceReference Path="WebService.asmx" />
        </Services>
    </asp:ScriptManager>
    
    <div>
    <script type="text/javascript">
        var s = '';
        WebService.HelloWorld(OnSuccess);
        function OnSuccess(result) {
            alert(result[0]);
        }
    </script>
    </div>
</form>

Answer 2

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server"
            TargetControlID="TextBox1"
            ServiceMethod="Selectassname"
            ServicePath="~/webservices/ASWebService.asmx"
            MinimumPrefixLength="0"
            CompletionSetCount="10"
            CompletionInterval="500"
            CompletionListItemCssClass="autocomplete_listItem"
            CompletionListHighlightedItemCssClass="autocomplete_highlightedListItem"
            >
            </cc1:AutoCompleteExtender>
页面调用代码浏览页面就成了计算后的

Answer 3

can be dirty-fixed by using items.Add("\"12345\"") instead.

Answer 4

[WebMethod]
        public string[] Selectassname(string prefixText, int count)
        {
            List<string> results = new List<string>(count);
            string sql = "select distinct top 10(assName) from Assign where assName like '" + prefixText + "%'";
            DataTable dt = new DataTable();
            SqlHelper.FillDataTable(sql, dt);
            foreach (DataRow dr in dt.Rows)
            {
                if (dr["assName"].ToString() != "")
                {
                    results.Add("\""+dr["assName"].ToString()+"\"");
                }
            }
            return results.ToArray();
        }可以了，谢了
