完全披露，我处于必须动态学习VB脚本的情况。这是问题： 在VB 2010脚本任务中，我不得不在我的SSIS包中的多个脚本任务中硬编码DB2连接字符串。在VB 2005中，连接字符串被设置为变量，我已经为VB 2010做了。我已经将脚本任务中的变量声明为读/写。我的其他变量有效，但我的DB2和MS SQL连接字符串都需要硬编码才能工作。我看到的错误是＆＃34;＆＃39; Dts＆＃39;没有宣布。＆＃34;我确信它被声明为代码的其他部分使用正确工作的dts变量。我已经寻找解决方案，但还没有发现任何有效的方法。感谢您提供的任何见解。下面的代码清除敏感信息并替换为星号：

看起来.horizontal-navigation-bar nav ul li.active-link a:after {
background: none !important;
}
是Dts类中的实例属性（继承自ScriptMain）。
但是，您的Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase调用位于名为OleDbConnection()的其他类中，该类无法访问DB2RS类的实例变量或属性，例如ScriptMain 。
如果您不明白这一点，那么您应该退后一步并参加一个初学者Visual Basic编程课程，因为即使下一个解决方案可以帮助您，您也不会进一步学习。这是一些资源
解决当前问题的一种方法是将Dts作为参数传递给Dts来电。改变这一行：
DB2RS.SetDBCon()为：
If Not DB2RS.SetDBCon(db2Con, strError) Then Throw New Exception(strError)
然后，您需要将If Not DB2RS.SetDBCon(db2Con, Dts, strError) Then Throw New Exception(strError)
作为参数添加到Dts函数中。我认为SetDBCon()的类型是Dts，因此我将其包含在下方。如果这是错的，你需要调整那种类型..
