我对 C# 真的很陌生，而且我没有编写此代码。我只是应该找出错误的原因。
我们有几台数控机床。数据库是 SQL Server 2005。
根据我阅读代码后的理解，整个代码块应该：
- 将数据库中的文件夹“推送”到作业排队的 CNC 机床。
- 一旦文件夹在系统上工作，就会对其进行修订。此修订版本应该是“从”存储此修订版本的位置，并将其复制到“拉到”目的地。
- 文件夹在存储一段时间后被删除。
“推送”文件夹的代码块有效。这告诉我没有连接错误。此外，SQL Server 连接具有 SSPI 的安全性。
我还可以登录数据库，这意味着我的 Windows 凭据没有问题。如果我去 SQL Server Management Studio 登录服务器，编写查询也适用于有问题的表。
但是当“拉”代码运行时，我收到以下错误：
选择 Distinct Resource, PullFrom, NML_MADL_XfriInstructions Where PullFrom <> 'na' Order By PullFrom, PullTo:
登录失败: 未知用户名或密码错误
这是代码：
