c# - 在 C# 中运行 cmd

Question

有什么区别:

var startInfo = new ProcessStartInfo();
string path = Directory.GetCurrentDirectory() + @"\foldername";
startInfo.WorkingDirectory = path;
startInfo.FileName = path + @"\do_run.cmd";
startInfo.Arguments = "/c arg1 arg2";
Process.Start(startInfo);

和

var startInfo = new ProcessStartInfo();
string path = Directory.GetCurrentDirectory() + @"\foldername";
startInfo.FileName = @"C:\windows\system32\cmd.exe";
startInfo.Arguments = @"/c cd " + path + " && do_run arg1 arg2";
Process.Start(startInfo);

出于某种原因，第二个代码块可以正常工作，但第一个代码块不能。

其次，我无法在发布应用程序时使用我的C:目录，那么如何在Visual Studio项目文件夹中运行cmd.exe？

谢谢

像这样的东西:

using System.IO;
using System.Reflection;

... 

var startInfo = new ProcessStartInfo();

// We want a standard path (special folder) which is C:\windows\system32 in your case
// Path.Combine - let .Net make paths for you 
startInfo.FileName = Path.Combine(
  Environment.GetFolderPath(Environment.SpecialFolder.System), 
 "cmd.exe");

string path = Path.Combine(
  // If you want exe path; change into 
  //   Environment.CurrentDirectory if you want current directory
  // if you want current directory
  Path.GetDirectoryName(Assembly.GetEntryAssembly().Location), 
 @"foldername");

// ""{path}"" - be careful since path can contain space(s)
startInfo.Arguments = $@"/c cd ""{path}"" && do_run arg1 arg2";

// using : do not forget to Dispose (i.e. free unmanaged resources - HProcess, HThread)
using (Process.Start(startInfo)) {
  ... 
}
