C# 代码未启动 .exe 出现错误找不到文件名

Question

I really have no idea why this code isnt working. Everytime i get the error Cannot start process because a file name has not been provided. Even though i provided the path in which the EXE is located and verified it.

using System;
using System.Diagnostics;
using System.Diagnostics.Contracts;

namespace ProcessExitSample
{
    class testsandboxprogram
    {
        static void Main(string[] args)
        {
            Contract.Requires(args != null);
            try
            {
                var firstProc = new Process();
                Process.Start(@"PATH TO EXE I WANT TO LAUNCH");
                firstProc.EnableRaisingEvents = true;

                firstProc.Start();

                firstProc.WaitForExit();

                //so upon exit should run the second program here
                Console.WriteLine("First process exited: " + firstProc.ExitCode);

                var secondProc = new Process();
                Process.Start(@"PATH TO PROGRAM I WANT TO LAUNCH");
                secondProc.Start();

            }
            catch (Exception ex)
            {
                Console.WriteLine("Something went wrong sorry :(: " + ex.Message);
                return;
            }
        }
    }
}

Answer 1

String myexepath = @"C:\Program Files (x86)\Steam\steamapps\common\BattleBlock Theater\BattleBlockTheater.exe"

由于此路径包含，在双引号之间用空格将其括起来：

Process.Start("\""+myexepath+"\"");

Answer 2

            var firstProc = new Process();
            // Process.Start(@"PATH TO EXE I WANT TO LAUNCH");
            firstProc.EnableRaisingEvents = true;
            firstProc.Start();

You do not provide a path for your process to start. I commented out the irrelevant code, since is not related to the firstProc variable.

You probably want:

 firstProc.StartInfo.FileName = @"\Path\To\Exe";

Answer 3

The most obvious is try to run your PATH TO EXE I WANT TO LAUNCH in a command line environment and see if you get a self explanatory error.

If your path contains spaces you will see that your are trying to execute something problematic with spaces and you can then use the answer Graffito gave.
