SqlConnection引发异常 [英] SqlConnection throws an exception

问题描述

亲爱的专业人员，请为我解决以下问题.在我的.NET C#应用程序中，有以下代码:

Dear professionals please help me with the following problem. In my .NET C# application a have this code:

SqlConnection connection = new SqlConnection( SQLCONNECTION_STRING );

它在我的开发计算机上运行非常好，但是在Windows 2003 Server上引发了异常.该应用程序通过CGI运行，并具有完全信任"级别.我尝试了几个连接字符串，但我认为该字符串不会引起问题，因为即使此代码也会出现异常:

It works marvelous on my development machine but throws an exception on Windows 2003 server. The application runs through CGI and has "Full trust" level. I've tried several connections strings and I think the string doesn't cause the issue because even this code gets an exception:

SqlConnection connection = new SqlConnection();

谢谢.

我发现了两个奇怪的事实:

I found two weird facts:

1. 如果我将调试器连接到进程并简单地跟踪代码，它将起作用.
2. 如果我从命令行(而不是通过CGI按要求运行)运行应用程序，则可以使用.

所以我想CGI和SqlConnection交互有问题.有人知道吗?

So I guess something wrong with CGI and SqlConnection interaction. Does someone know about that?

感谢大家的回应.

编辑后添加:

这是我的连接字符串:提供程序= SQLOLEDB；数据源=(本地)；初始目录=用户；用户ID =用户；密码=密码；"

Here is my connection string: "Provider=SQLOLEDB;Data Source=(local);Initial Catalog=Users;User Id=user;Password=password;"

我还尝试了其中所述的几种可能的变体: http://www.connectionstrings.com/sql-server

I've also tried several possible variants as described there: http://www.connectionstrings.com/sql-server

请在以下找到有关异常的信息:

即使无参数构造函数也会给出异常.因此，我认为问题不在于连接字符串中.我可以看到堆栈跟踪告诉了一些有关路径中的非法字符"的信息.因此，我将尝试深入研究并找出答案.但是也许有人已经知道解决方法.

Even parameterless constructor gives an exception. So I don't think the problem is in the connection string. I can see stack trace tells something about "Illegal characters in path". So I will try to drill down and find out. But maybe someone already knows solution.

推荐答案

此问题通常与您的配置文件中的问题有关.您可能想重新创建它.

This problem is generally related to a problem in your configuration file. You might want to re-create that.
