Question

我的代码存在这个奇怪的问题。当它在我的本地机器上运行时它工作得很好，但是当我在服务器上发布它时，它突然无法检索类型。它似乎不会导出所有文件。我收到的错误 Error Received

我尝试了CodeFile并且它可以正常工作，但我稍后在无法加载ObjectDataSource的地方收到同样的错误。我检查了继承，看起来还不错......

以下是代码：

    </form>

它是Default.aspx.cs，它是空的

using System;

namespace TheDatabase
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }


    }

}

和我的对象数据源

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;

namespace TheDatabase
{
    public class SQLUlaznaTabela
    {
        public string Vehicle { get; set; }
        public string VCC { get; set; }
        public string QuantM1 { get; set; }
        public string VehM1 { get; set; }
        public string JCI { get; set; }
        public string Description { get; set; }
    }

    public class PNDetailsDataAccessLayer
    {
        public PNDetailsDataAccessLayer()
        {

        }
        public List<SQLUlaznaTabela> GetResult(string VehicleID)
        {
            List<SQLUlaznaTabela> ulaz = new List<SQLUlaznaTabela>();
            string SC = ConfigurationManager.ConnectionStrings["QuotationCalculationDB"].ConnectionString;

            using (SqlConnection con = new SqlConnection(SC))
            {
                SqlCommand cmd = new SqlCommand("Select Vehicle, VCC,QuantM1,VehM1,Description from ProdPerVehicleLastYear where Vehicle = @Vehicle", con);
                SqlParameter param = new SqlParameter("@Vehicle", VehicleID);
                cmd.Parameters.Add(param);
                con.Open();
                SqlDataReader rdr = cmd.ExecuteReader();
                while (rdr.Read())
                {
                    SQLUlaznaTabela ulazniRed = new SQLUlaznaTabela();
                    ulazniRed.Vehicle = rdr["Vehicle"].ToString();
                    ulazniRed.VCC = rdr["VCC"].ToString();
                    ulazniRed.QuantM1 = rdr["QuantM1"].ToString();
                    ulazniRed.VehM1 = rdr["VehM1"].ToString();
                    ulazniRed.Description = rdr["Description"].ToString();
                    ulaz.Add(ulazniRed);
                }

            }

            return ulaz;
        }
    }
}

我很困惑，因为我的代码没问题，结果发现我还没有在IIS中启动我的应用程序。对我感到羞耻......

CodeBehind无法加载类型
