我一直遇到以下编译错误:

            Compilation Error

只想在一般情况下以及在ASP和C#中编写新的编程.我以前使用相同的代码连接到数据库,它工作正常,但现在我得到的错误,我不太熟悉如何解决.下面是我的aspx页面和我的web.config的代码.

            <%@Page Language="C#" MasterPageFile="MasterPage/AtronsSiteMaster.master"%>
            <%@ Import Namespace="System.Data"%>
            <%@ Import Namespace="System.Data.Common"%>

我正在写一个ASP.NET页面.我正在尝试编写一个查询来获取列中存在特定值的总次数:

课程表:

CourseSubject

ECT
HCI
HCI

我只想返回name2出现的次数.

到目前为止我有这个但是一直出错:

comm.CommandText = "SELECT CourseSubject, COUNT(*) AS ETC FROM Courses;

我一直收到输入字符串格式不正确的错误.我不明白为什么会这样.我正在尝试写入我的数据库,而Zip代码是一个数字.我已经尝试将其更改为字符串,但这会导致在执行非查询时缺少参数.

Input string was not in a correct format.
