Well, you could start a new cmd.exe process and use stdio and stdout to send and recieve data.
好吧，您可以启动一个新的 cmd.exe 进程并使用 stdio 和 stdout 来发送和接收数据。
ProcessStartInfo psi = new ProcessStartInfo("cmd.exe")
{
RedirectStandardError = true,
RedirectStandardInput = true,
RedirectStandardOutput = true,
UseShellExecute = false
};
Process p = Process.Start(psi);
StreamWriter sw = p.StandardInput;
StreamReader sr = p.StandardOutput;
sw.WriteLine("Hello world!");
sr.Close();

A single console is attached to any given process. So in short you can not. But there are ways to "fake it"
单个控制台附加到任何给定进程。所以总之你不能。但有办法“伪造”

The following fires off an application-dependent number of console windows and stores the amount and parameters for the console inside a String Dictionary that is then looped to generate the required amount of spawned console apps. You would only need the process stuff if only spawning one of course.
下面的代码会触发依赖于应用程序的控制台窗口数量，并将控制台的数量和参数存储在一个字符串字典中，然后循环生成所需数量的生成的控制台应用程序。如果只产生一个当然，你只需要进程的东西。
//Start looping dic recs and firing console
foreach (DictionaryEntry tests in steps)
{
try
{
Process runCmd = new Process();
runCmd.StartInfo.FileName = CONSOLE_NAME;
runCmd.StartInfo.UseShellExecute = true;
runCmd.StartInfo.RedirectStandardOutput = false;
runCmd.StartInfo.Arguments = tests.Value.ToString();
if (cbShowConsole.Checked)
{
runCmd.StartInfo.CreateNoWindow = true;
runCmd.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
}
else
{
runCmd.StartInfo.CreateNoWindow = false;
runCmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
}
runCmd.Start();
}
catch (Exception ex)
{
string t1 = ex.Message;
}
}
Note this is intended either to run hidden (CreateNoWindow) or visible.
请注意，这旨在运行隐藏 (CreateNoWindow) 或可见。
