类文件无法联机工作，C#

Question

我创建了一个类文件，为我正在开发的一个用C#编写的网站生成日历事件。在本地，我可以添加类using myNamespace，并且没有明显的错误告诉我找不到类型或命名空间。将鼠标悬停在代码中的类名上，它显示了正确的定义。

然而，当我将文件上传到web服务器时，我会收到错误：The type or namespace name 'vCalendar' could not be found (are you missing a using directive or an assembly reference?)

在visual studio中，我可以将鼠标悬停在下面的vCalendar上：

vCalendar myAppointment = new vCalendar("TCHR", "www.website.com");

悬停在第一个上会给我一个class myNamespace.vCalendar的消息，而悬停在第二个上则会给我vCalendar.vCalendar(string identifier, string netAddress)的消息。

我的vCalendar类看起来像：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace myNamespace
{
    public class vCalendar
    {
        private string identifier;
        private string netaddress;
        // Constructor:
        public vCalendar(string identifier, string netaddress)
        {
            this.identifier = identifier;
            this.netaddress = netaddress;
        }
        public string CreateAppointment(string uid, string organizer, DateTime startMeeting, DateTime endMeeting, string location, string summary, string description, int priority, int sequence)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.AppendLine("BEGIN:VCALENDAR");
            sb.AppendLine("PRODID:-// " + identifier + "//" + netaddress + "//EN");
            sb.AppendLine("VERSION:2.0");
            sb.AppendLine("METHOD:REQUEST");
            sb.AppendLine("BEGIN:VEVENT");
            sb.AppendLine("UID:" + uid);
            sb.AppendLine("SEQUENCE:" + sequence.ToString());
            sb.AppendLine("ORGANIZER:" + organizer);
            sb.AppendLine("DTSTART:" + ConvertToISO8601DateTime(startMeeting));
            sb.AppendLine("DTEND:" + ConvertToISO8601DateTime(endMeeting));
            sb.AppendLine("DTSTAMP:" + ConvertToISO8601DateTime(DateTime.Now));
            sb.AppendLine("LOCATION:" + location);
            sb.AppendLine("SUMMARY:" + summary);
            sb.AppendLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:" + description);
            sb.AppendLine("TRANSP:OPAQUE");
            sb.AppendLine("ACTION:DISPLAY");
            sb.AppendLine("PRIORITY:" + priority.ToString());
            sb.AppendLine("CLASS:PUBLIC");
            sb.AppendLine("END:VEVENT");
            sb.AppendLine("END:VCALENDAR");
            return sb.ToString();
        }
        public string UpdateAppointment(string uid, string organizer, DateTime startMeeting, DateTime endMeeting, string location, string summary, string description, int priority, int sequence)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.AppendLine("BEGIN:VCALENDAR");
            sb.AppendLine("PRODID:-// " + identifier + "//" + netaddress + "//EN");
            sb.AppendLine("VERSION:2.0");
            sb.AppendLine("METHOD:REQUEST");
            sb.AppendLine("BEGIN:VEVENT");
            sb.AppendLine("UID:" + uid);
            sb.AppendLine("SEQUENCE:" + sequence.ToString());
            sb.AppendLine("ORGANIZER:" + organizer);
            sb.AppendLine("DTSTART:" + ConvertToISO8601DateTime(startMeeting));
            sb.AppendLine("DTEND:" + ConvertToISO8601DateTime(endMeeting));
            sb.AppendLine("DTSTAMP:" + ConvertToISO8601DateTime(DateTime.Now));
            sb.AppendLine("LOCATION:" + location);
            sb.AppendLine("SUMMARY:" + summary);
            sb.AppendLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:" + description);
            sb.AppendLine("TRANSP:OPAQUE");
            sb.AppendLine("ACTION:DISPLAY");
            sb.AppendLine("PRIORITY:" + priority.ToString());
            sb.AppendLine("CLASS:PUBLIC");
            sb.AppendLine("END:VEVENT");
            sb.AppendLine("END:VCALENDAR");
            return sb.ToString();
        }
        public string CancelAppointment(string uid, string organizer, DateTime startMeeting, DateTime endMeeting, string location, string summary, string description, int priority, int sequence)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.AppendLine("BEGIN:VCALENDAR");
            sb.AppendLine("PRODID:-// " + identifier + "//" + netaddress + "//EN");
            sb.AppendLine("VERSION:2.0");
            sb.AppendLine("METHOD:CANCEL");
            sb.AppendLine("BEGIN:VEVENT");
            sb.AppendLine("UID:" + uid);
            sb.AppendLine("SEQUENCE:" + sequence.ToString());
            sb.AppendLine("ORGANIZER:" + organizer);
            sb.AppendLine("DTSTART:" + ConvertToISO8601DateTime(startMeeting));
            sb.AppendLine("DTEND:" + ConvertToISO8601DateTime(endMeeting));
            sb.AppendLine("DTSTAMP:" + ConvertToISO8601DateTime(DateTime.Now));
            sb.AppendLine("LOCATION:" + location);
            sb.AppendLine("SUMMARY:" + summary);
            sb.AppendLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:" + description);
            sb.AppendLine("TRANSP:OPAQUE");
            sb.AppendLine("ACTION:DISPLAY");
            sb.AppendLine("PRIORITY:" + priority.ToString());
            sb.AppendLine("CLASS:PUBLIC");
            sb.AppendLine("END:VEVENT");
            sb.AppendLine("END:VCALENDAR");
            return sb.ToString();
        }
        private static string ConvertToISO8601DateTime(DateTime dt)
        {
            string _dt = string.Format("{0:yyyyMMddTHHmmss}", dt); // ISO 8601
            return _dt;
        }
    }
}

我真的不确定我做错了什么。我已将所有文件上传到网上。我在班级档案里做错什么了吗？我是否需要以using命令以外的其他方式包含此内容？

要从网站使用C#class，您需要将项目编译为DLL，然后将DLL复制到web服务器，以便您的web代码可以使用它。
