无法从数据库打印数据：C#代码抛出异常求助

Hey there! I get that you're running into an exception when trying to print data from your myT table using C#—let's get this sorted out. To help me pinpoint exactly what's going wrong, could you share a few more specifics:

• Full C# code snippet: Instead of a screenshot, drop the actual code here wrapped in triple backticks (csharp ... ) so I can dig into how you're accessing and printing the data.
• Relevant App.config sections: Especially the connection string (feel free to mask any sensitive details like database passwords!).
• Exact exception details: Let me know the exception type (e.g., SqlException, NullReferenceException), the full error message, and if you have it, the stack trace. This will tell us exactly where the breakdown is happening.

Common culprits here could be an incorrect connection string, a malformed query for your myT table, null values causing issues when printing, or improper disposal of database connections. Once you share the details, we can narrow it down quickly.
