私のプロジェクトでは、リストを生成するための WebService があります。WebService を実行するNullReference Exception
と、c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Config\DefaultWsdlHelpGenerator.aspx
.
私のコードの問題は何ですか?
私が試したコードは次のとおりです。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data.SqlClient;
using System.Data;
using SubSonic;
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class AutoComplete : System.Web.Services.WebService
{
public AutoComplete()
{
//InitializeComponent();
}
public string[] Getlist(string keywordstartswith)
{
IList<string> output = new List<string>();
Dictionary<string, string> mydict = new Dictionary<string, string>();
string QueryString = System.Configuration.ConfigurationManager.ConnectionStrings ["IUMSNXG"].ToString();
IDataReader obj_result = SearchApp.DBCon.LRS_SP_CBFM_Sel(keywordstartswith).GetReader();
DataTable dt = new DataTable();
dt.Load(obj_result);
if(dt.Rows.Count > 0)
{
while (obj_result.Read())
{
output.Add(string.Format("{0}~{1}", obj_result["AnimalCode"].ToString().TrimEnd(), obj_result["pk_animalid"].ToString().TrimEnd()));
}
}
return output.ToArray();
}
}
私が得ているソースエラーは次のとおりです。
Line 1333:
Line 1334: OperationBinding FindHttpBinding(string verb) {
Line 1335: foreach (ServiceDescription description in serviceDescriptions) // Getting Error Here
{
Line 1336: foreach (Binding binding in description.Bindings) {
