MVC3 EE CTP - 初始化字符串的格式不符合从索引 0 开始的规范

Question

我有小型 MVC 3 实体代码优先应用程序，我在本地数据库中创建了表，并备份了表并恢复了 winhost Web 托管数据库上的数据。

在我的 web.config 中，我已将连接字符串更改为 winhost 连接启动。它在我的桌面上运行。

我将本地应用程序转移到 Windows，当访问该应用程序时出现此错误。

来自此方法的错误。

  public ActionResult ListRecords()
        {
            var query = from e in db.Envelopes
                        orderby e.ReportDate descending
                        select e;
            IEnumerable<Envelopes> top10 = query.Take(25);

            return View(top10.ToList<Envelopes>());
        }

Answer 1

为什么还在使用CTP？该版本已经发布有一段时间了。升级，然后查看问题是否仍然存在。这可能是一个固定的问题。

Answer 2

堆栈跟踪指出您的连接字符串存在问题。

修复您的连接字符串，问题就会消失。
