c＃当字符串数据超过255个字符时插入Excel时出错 [英] c# Error inserting to Excel when string data is more than 255 chars

问题描述

我正在尝试将一些数据导出到Excel。我正在使用OLEDB 12.连接字符串看起来像：

I am trying to export some data to Excel. I am using OLEDB 12. The connectio string looks like:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR=YES;'"

INSERT查询但是，当目标列中的数据超过255个字符时，我会收到异常。

And I use an INSERT query. But whenever the data in a target column exceeds 255 chars, I get an exception.

Exception Details: System.Data.OleDb.OleDbException: The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.

在SO上有一个类似的帖子： Excel无法插入超过255个字符？但是不是进入c＃，

There is a similar post on SO: Excel unable to insert more than 255 chars? but it is not into c#,

我还提到了 http://support.microsoft.com/kb/213841 并没有得到任何解决方案。

I also referred to http://support.microsoft.com/kb/213841 and not getting any solution.

请帮助。
