运行 电子邮件 (POP3) 代码时，SSIS 中的 C# 脚本任务出错
Error in C# script task in SSIS when running code for email (POP3)
我有一个电子邮件脚本任务，我试图用它来通过 SSIS script task 传递变量。我确保我拼写正确并且我的代码可以编译。我收到此错误：
Exception has been thrown by the target of an invocation.
at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)
at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams)
at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()
我承认我是新手，如果有简单的解决方法，我深表歉意。
我添加了以下两个命名空间：
using System.Net;
using System.Net.Mail;
在下面的代码中，我硬编码了凭据的用户名和密码。我可以将其更改为变量（我认为。）
当我直接在代码中将值硬编码到变量时，它仍然给出相同的错误。代码构建和清理都很好，因此感谢任何帮助。谢谢。

菜鸟失误！代码在常规 C# 控制台中不起作用。在那里调试它，进行必要的调整，然后转瞬即逝！对于垃圾邮件，我深表歉意。
