SqlConnection抛出异常

Question

亲爱的专业人士请帮助我解决以下问题.在我的.NET C#应用程序中,有一个代码:

SqlConnection connection = new SqlConnection( SQLCONNECTION_STRING );

它在我的开发机器上运行得非常好,但在Windows 2003服务器上抛出异常.该应用程序通过CGI运行并具有"完全信任"级别.我已经尝试了几个连接字符串,我认为字符串不会导致问题,因为即使这个代码也会出现异常:

SqlConnection connection = new SqlConnection();

谢谢.

我发现了两个奇怪的事实:

1. 如果我将调试器连接到进程并简单跟踪代码,它就可以工作.
2. 如果我从命令行运行应用程序(不是根据需要通过CGI),它可以工作.

所以我猜CGI和SqlConnection交互有问题.有人知道吗？

谢谢大家的回复.

编辑添加:

这是我的连接字符串:"Provider = SQLOLEDB; Data Source =(local); Initial Catalog = Users; User Id = user; Password = password;"

我还尝试了几种可能的变体,如:http://www.connectionstrings.com/sql-server

请在下面找到有关例外情况的信息:

The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception.

   at Test.Database.UpdateSQLServerDatabase(IDictionary`2 fields, String regName, StringBuilder regCode)

即使是无参数构造函数也会出现异常.所以我不认为问题出在连接字符串中.我可以看到堆栈跟踪讲述了"路径中的非法字符".所以我会尝试深入了解并找出答案.但也许有人已经知道解决方案.

此问题通常与配置文件中的问题有关.您可能想要重新创建它.
