Question

当我尝试运行此代码时，我不断收到错误System.ComponentModel.Win32Exception: The specified executable is not a valid application for this OS platform.。

似乎myProcess.Start()行是问题所在。谁能帮助我。

        string python = @"C:\Users\mk\Desktop\A.py";

        // python app to call 
        string myPythonApp = "sum.py";

        // dummy parameters to send Python script 
        int x = 2;
        int y = 5;

        // Create new process start info 
        ProcessStartInfo myProcessStartInfo = new ProcessStartInfo(python);

        // make sure we can read the output from stdout 
        myProcessStartInfo.UseShellExecute = false;
        myProcessStartInfo.RedirectStandardOutput = true;

        // start python app with 3 arguments  
        // 1st arguments is pointer to itself,  
        // 2nd and 3rd are actual arguments we want to send 
        myProcessStartInfo.Arguments = myPythonApp + " " + x + " " + y;

        Process myProcess = new Process();
        // assign start information to the process 
        myProcess.StartInfo = myProcessStartInfo;

        Console.WriteLine("Calling Python script with arguments {0} and {1}", x, y);

        // start the process 
        myProcess.Start();

    }
}

}

您试图将A.py作为可执行文件（例如.exe）调用，但不是（只是文本，不是程序集）。

相反，您可以通过CMD调用Python以运行A.py，并将sum.py作为附加参数传递。

这是一个例子：

ProcessStartInfo myProcessStartInfo = new ProcessStartInfo("cmd.exe"); 

// run python from console.
myProcessStartInfo.UseShellExecute = false;
myProcessStartInfo.RedirectStandardOutput = true;
myProcessStartInfo.Arguments = "/C python A.py " + myPythonApp + " " + x + " " + y; 

Process myProcess = new Process(); 
myProcess.StartInfo = myProcessStartInfo;
// start the process 
myProcess.Start();

指定的可执行文件不是此OS平台的有效应用程序。
