【问题描述】：

我有一个 ADO.Net 连接，它使用 ODBC 数据源连接到我们的大型机。当它连接到 DataReader 源时，Datareader 立即失败。我假设至少连接工作正常，因为 SqlCommand 中的 Select * From（不是我正在使用的）将正确显示列映射下的所有可用列。当试图转储到一个简单的平面文件时，我明白了。

【问题讨论】：

主机上的数据库是什么？

源 RDBMS 中的数据类型是什么，它们如何映射到数据流中的列？您是否碰巧将事务级别从默认的 Supported 更改为 Required？

一切都是DT_WSTR，和平面文件一样，还是支持事务级的。老实说，此时我只是想从大型机中取出任何东西，所以我只提取了两列。

想通了。这是 .Net 框架更新的问题。您可以通过将文本文件添加到数据阅读器的错误输出来解决此问题。在这里找到了答案。 blogs.msdn.com/b/sqlblog/archive/2009/04/09/…

【参考方案1】：

发现这是 .Net 框架更新的问题。在错误输出中添加一个文本文件解决了这个问题。
