Process.Start找不到文件？

问题描述

我正在做一个助手，我希望它打开应用程序。它只会打开某些应用程序，例如chrome.exe（Chrome）和devenv.exe（Visual Studio）。

我还有4个应用程序，分别是Spotify.exe（Spotify），discord.exe（discord），obs64.exe（OBS Studio）和Steam.exe（Steam）。当我告诉助手打开该特定应用程序时出现错误：

“ System.ComponentModel.Win32Exception：'系统找不到指定的文件'”。

对于所有这些应用程序，错误都是相同的。这是我的代码：

        Grammar ZeroTwoGrammar;

        bool ZeroTwoSearch = false;

        public Form1()
        {
            InitializeComponent();

            // Sound player

            ZeroTwoGreeting = new Soundplayer(@"c:/Users/User/Desktop/Zero Two Sound Files/dahling ohaio.wav");

            // Speech Synthesizer

            ZeroTwo = new SpeechSynthesizer();      

            // Speech Recognition

            ZeroTwoears = new SpeechRecognitionEngine();
            Choices list = new Choices();

            list.Add(new string[] { 

                // Greetings

                "Ohaio,zero two",// Google search

            } );

            ZeroTwoGrammar = new Grammar(new GrammarBuilder(list));

            try
            {

                ZeroTwoears.RequestRecognizerUpdate();

                ZeroTwoears.LoadGrammar(ZeroTwoGrammar);

                ZeroTwoears.SpeechRecognized += ZeroTwoears_SpeechRecognized;

                ZeroTwoears.SetInputToDefaultAudioDevice();

                ZeroTwoears.RecognizeAsync(RecognizeMode.Multiple);

            }
            catch { }

        }
        private void ZeroTwoears_SpeechRecognized(object sender,SpeechRecognizedEventArgs e)
        {
            String ZamdiesLines = e.Result.Text;
            button1.Text = ZamdiesLines;

            if (ZeroTwoSearch == true)
            {
                ZeroTwoGreeting.Play();
                Process.Start("https://www.google.com/search?q=" + ZamdiesLines);

                button1.Text = "fired!";
            }

            if (ZeroTwoSearch == false)
            {
                switch (ZamdiesLines)
                {


                    case ("Ohaio,zero two"):
                        ZeroTwoGreeting.Play();
                        break;


                    case ("Zero two,open discord"):

                        break;


                    case ("Zero two,open google"):
                        ZeroTwoGreeting.Play();

                        Process.Start("devenv.exe");
                        break;


                    case ("Zero two,open spotify"):
                        ZeroTwoGreeting.Play();
                        Process.Start("Spotify.exe");
                        break;


                    case ("Zero two,open steam"):

                    case ("Zero two,open obs"):
                        ZeroTwoGreeting.Play();
                        Process.Start("obs64.exe");
                        break;
                }
            }
        }

}

解决方法

Chrome.exe和Devenv.exe自动运行的原因是，这两个应用程序的路径（它们所在的文件夹）都在系统Path环境变量中声明。有两种解决方案。

您必须通过设置Discoord.exe应用程序的完整路径来调用它，例如：

Process.Start（“ C：\\ Users \\ AppData \\ Local \\ Discord \\ app-0.0.307 \\ Discord.exe”）;
在计算机系统中设置环境路径。看下面的屏幕截图：

c#c#process.start
