来自C#donds'；你跑的顺序不对吗？

我有以下代码：

using System;

namespace MyProject
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = args[1];
            string output = args[3];

            Console.WriteLine("Finished parsing input");

            // runs an executable file called myexe.exe
            // this exe creates an output file with the hardcoded name exeoutput.txt
            string runexe = string.Format("/C myexe.exe -i {0}", input);
            System.Diagnostics.Process.Start("CMD.exe", runexe);

            Console.WriteLine("Finished running exe");

            // moves the output created by myexe.exe to a new location
            string moveOutput = string.Format("/C move exeoutput.txt {0}", output);
            System.Diagnostics.Process.Start("CMD.exe", moveOutput);

            Console.WriteLine("Finished moving output");
        }
    }
}

我使用命令

MyProject.exe-I input.txt-o output.txt

运行此代码

第一次运行命令时，我得到以下输出：

Finished parsing input
Finished running exe
Finished moving output
C:\Users\me\source\repos\MyProject\MyProject\bin\Debu\netcoreapp3.1>The system cannot find the file specified
[some output from myexe.exe]

Finished parsing input
Finished running exe
Finished moving output
C:\Users\me\source\repos\MyProject\MyProject\bin\Debu\netcoreapp3.1> 1 file(s) moved.
[some output from myexe.exe]

第二次运行时，我得到以下输出：

Finished parsing input
Finished running exe
Finished moving output
C:\Users\me\source\repos\MyProject\MyProject\bin\Debu\netcoreapp3.1>The system cannot find the file specified
[some output from myexe.exe]

Finished parsing input
Finished running exe
Finished moving output
C:\Users\me\source\repos\MyProject\MyProject\bin\Debu\netcoreapp3.1> 1 file(s) moved.
[some output from myexe.exe]

看起来C代码首先执行print语句，其次执行move file命令，然后第三次执行

myexe.exe

。为什么会发生这种情况？我如何执行该命令？

像这样处置流程对象

  using (Process myProcess = new Process())
                {
                    myProcess.StartInfo.UseShellExecute = false;
                    // You can start any process, HelloWorld is a do-nothing example.
                    myProcess.StartInfo.FileName = "C:\\HelloWorld.exe";
                    myProcess.StartInfo.CreateNoWindow = true;
                    myProcess.Start();
                    // This code assumes the process you are starting will terminate itself. 
                    // Given that is is started without a window so you cannot terminate it 
                    // on the desktop, it must terminate itself or you can do it programmatically
                    // from this application using the Kill method.
                }

您是否希望C#进程等待启动的进程完成？您需要额外的代码。我认为在运行第一个CMD.EXE之后，您应该等待终止，而不是启动另一个CMD.EXE，这是一个进程。WaitForExit（）此行

string runexe=string.Format（“/C myexe.EXE-I{0}，input）；

不会编译

进程。Start

启动进程，但不会等待它完成。您需要保留对已启动进程的引用，然后调用

thatProcessVariable.WaitForExit（）

。我一直想知道为什么没有人在来这里提问之前查看文档。关于如何启动流程并保留对已启动流程的引用，有数千个示例，因此您可以WaitForExit。既然OP希望等待，请参见。？
