为什么Process.Start（“cmd.exe”，进程）;不行？ [英] Why does Process.Start("cmd.exe", process); not work?

问题描述

这样做：

  Process.Start（control，/ name Microsoft.DevicesAndPrinters）; 
  

但这不：（它只是打开一个命令提示符。）

  ProcessStartInfo info = new ProcessStartInfo（cmd.exe）; 
 info.Arguments =control / name Microsoft.DevicesAndPrinters; 
 Process.Start（info）; 
  

为什么？

但是第二个应该工作。）

解决方案

这是因为 cmd.exe 需要一个 / K 切换来执行作为参数传递的进程。尝试下面的代码

  ProcessStartInfo info = new ProcessStartInfo（cmd.exe）; 
 info.Arguments =/ K control / name Microsoft.DevicesAndPrinters; 
 Process.Start（info）; 
  

编辑：已更改为 / K 如果在运行命令后要关闭 cmd.exe ，可以使用 / C >

This works:

Process.Start("control", "/name Microsoft.DevicesAndPrinters");

But this doesn't: (It just opens a command prompt.)

ProcessStartInfo info = new ProcessStartInfo("cmd.exe");
info.Arguments = "control /name Microsoft.DevicesAndPrinters";
Process.Start(info);

Why?

(Yes, I know they're not identical. But the second one "should" work.)

解决方案

This is because cmd.exe expects a /K switch to execute a process passed as an argument. Try the code below

ProcessStartInfo info = new ProcessStartInfo("cmd.exe");
info.Arguments = "/K control /name Microsoft.DevicesAndPrinters";
Process.Start(info);

EDIT: Changed to /K above. You can use /C switch if you want cmd.exe to close after it has run the command.
