Question

我的代码中出现了这些奇怪的编译器错误：

} expected

Invalid token 'return' in class, struct, or interface member declaration

Method must have a return type

Identifier expected

; expected

Type or namespace definition, or end-of-file expected

所有这些错误都以GetTicketInfo方法为中心。

这段代码正在编译和工作好几天，现在突然间Visual Studio 2012出现了问题。

我做错了什么？代码如下。

    public static HelpDeskTicket GetTicketInfo(int ticketId, DbDataContext dc)

        return GetInfo(ticketId, dc, _default).SingleOrDefault();
    }
  }
}

Answer 1

public static HelpDeskTicket GetTicketInfo(int ticketId, DbDataContext dc)
{
    private DateTime _default = new DateTime(1900, 1, 1);

    return GetInfo(ticketId, dc, _default).SingleOrDefault();
}

我很肯定这个代码几天前没有工作，使用访问修饰符private就像你做的那样不合法，只需删除它。

Answer 2

虽然这不是StackOverflow倾向于欣赏的问题类型 - 但我们都遇到过愚蠢的错误。这是一个语法问题。

从方法中删除private关键字。

private DateTime _default = new DateTime(1900, 1, 1);

到

DateTime _default = new DateTime(1900, 1, 1);

编译时出现多个意外错误
