指定的可执行文件不是该操作系统平台的有效应用程序。

我不断收到错误消息System.ComponentModel.Win32Exception: The specified executable is not a valid application for this OS platform.当我尝试运行这段代码时。

看来这条线myProcess.Start()是问题所在。 谁能帮我吗。

        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();

    }
}

}

您正在尝试致电A.py作为可执行文件，例如.exe，但它不是（它只是文本，而不是程序集）。

相反，你可以通过CMD调用Python来运行A.py，并传入sum.py作为额外的参数。

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();
