我不知道该怎么做才能解决此问题，并且想知道是否有人知道我可以解决该问题.

As I recently posted I am trying to develop my own program for the company that I work for. I have made some major progress in it. I am now getting this:

System.Data.SqlServerCe.SqlCeException was unhandled
Message=The column name is not valid. [ Node name (if any) = ,Column name = Date of Unit Sold ]
Source=SQL Server Compact ADO.NET Data Provider
HResult=-2147467259

I have no idea what I did to create this problem and was wondering if anyone knew what I could do to fix it.

推荐答案

好.让我们在上面翻阅您的转储.

1.您得到了System.Data.SqlServerCe.SqlCeException
2.抱怨The column name is not valid. .... Column name = Date of Unit Sold
3.引发异常的呼叫来自....\_MyDatabase_1DataSet.Designer.cs:line 1701
4.依次从....\Dons App Start build\Form1.cs:line 40
调用
这些应该足以让您开始寻找问题的线索.
太难了吗?

彼得

OK. Let''s walk through your dump above.

1. You got System.Data.SqlServerCe.SqlCeException
2. It''s complaining that The column name is not valid. .... Column name = Date of Unit Sold
3. The call that raised the exception came from ....\_MyDatabase_1DataSet.Designer.cs:line 1701
4. That, in turn, was called from ....\Dons App Start build\Form1.cs:line 40

Those should be enough clues for you to start looking for the problem.
Is that too hard?
