Question

我收到了这个错误：

错误： at System.RuntimeMethodHandle.InvokeMethod（Object target，Object [] arguments，Signature sig，Boolean constructor） at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal（Object obj，Object [] parameters，Object [] arguments）在System.Reflection.RuntimeMethodInfo.Invoke（Object obj，BindingFlags invokeAttr，Binder binder，Object []参数，CultureInfo文化） at System.RuntimeType.InvokeMember（String name，BindingFlags bindingFlags，Binder binder，Object target，Object [] providedArgs，ParameterModifier [] modifiers，CultureInfo culture，String [] namedParams）在Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript（）

@Arumugam，在脚本任务中，输入断点。如果您在第一次尝试/捕获之前失败，请将第一个断点放在这一行：

SftpClient objSFTPclient = new SftpClient（HostName，UserName，objKeyFile）;

如果您发布的堆栈跟踪发生在托盘/ catch中，请将第一个断点放在此行上：

objSFTPclient.Connect（）;

我不是Renci.SshNet专家，但似乎代码试图通过SSIS打开shell，因此调用失败。如果Renci.SshNet有一个用于sftp文件传输的命令行 - 这就是你尝试做的事情，那就使用执行进程任务。

使用winscp将文件上传到sFTP的脚本导致错误
