，當我有我嘗試使用通過SSIS script task將變量傳遞到電子郵件腳本任務。我確信我拼寫正確，我的代碼編譯。我得到這個錯誤：錯誤在SSIS C＃腳本任務運行的電子郵件（POP3）代碼
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()
我會承認在這裏是一個新手，如果有一個簡單的解決方案，我很抱歉。
我已經添加了以下兩個命名空間：
using System.Net;
using System.Net.Mail;
在下面的代碼，我硬編碼我對憑證的用戶名和密碼。我可以改變一個變量（我認爲）
當我硬編碼值直接在代碼中的變量，但它仍然給出了同樣的錯誤。代碼的構建和清理非常好，所以任何幫助表示讚賞。謝謝。
