using System.Web.Services;
using System.Configuration;
using System.Web.UI.WebControls;

/// <summary>
/// Summary description for MyService

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
 [System.Web.Script.Services.ScriptService()]
public class MyService : System.Web.Services.WebService {

    public MyService()
    {

        using (NovartisModel.NovartisEntities cntxt = new NovartisModel.NovartisEntities())

            var res = from q in cntxt.tblTerritory where q.Territory_Name.ToLower().StartsWith(prefix.ToLower()) select q.Territory_Name;
            List<string> responses = new List<string>();
            foreach(string item in res)
            {
                responses.Add(item);
            }

答

Quote：

请注意，您可以使用您选择的名称替换GetCompletionList，但返回类型和参数名称和类型必须完全匹配，包括大小写。

Note that you can replace "GetCompletionList" with a name of your choice, but the return type and parameter name and type must exactly match, including case.

尝试下面

try below

[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static string[] ReturnTerritory(string prefixText, int count)
{
        using (NovartisModel.NovartisEntities cntxt = new NovartisModel.NovartisEntities())
        {
            var res = from q in cntxt.tblTerritory where q.Territory_Name.ToLower().StartsWith(prefixText.ToLower()) select q.Territory_Name;
            List<string> responses = new List<string>();
            foreach(string item in res)
            {
                responses.Add(item);
            }
            return responses.ToArray();
        }
}
