cmd.exe中的TELNET命令与c#中的Socket编程的区别

我有一台机器，通过传递ip地址和端口号，使用cmd.exe中的TELNET命令连接到该机器。连接成功后，我会传递一些命令来完成任务。但每次打开命令提示符并执行上面提到的任务并不是客户想要的。他们希望流程自动化。凭借在c#中使用Socket程序的一些经验，我试图通过使用ip地址和端口号的Socket程序进行连接，并传递命令来完成任务，但套接字编程没有完成任务。

所以我的问题是，是否可以使用c#中的Socket编程在cmd.exe中执行telnet命令完成的相同任务，如果可以，如何执行？

请帮帮我。提前谢谢。

这是我在c#中的代码，用来连接到机器，但它无法完成所需的任务。它无法执行cmd.exe中TELNET命令正在执行的任务。.
