sql:'MYDataContext'不包含'InsertOnSubmit'的定义

问题描述

我正在尝试向表中添加一行:

I am trying to add a row to a table:

MYDataContext dc = new MYDataContext("MYConnectionString");

    using (MYDataContext db = new MYDataContext("MYConnectionString"))
    {
        NotificationLog n = new NotificationLog();
        n.result = result;
        n.context = message;
        n.tomobiles = phoneprefix + phone;
        n.datesent = DateTime.Now;
        n.SMSprovider = provider;
        db.InsertOnSubmit(n);
        db.SubmitChanges();
    }

但我收到此错误:

我该如何解决?
