Question

我正在尝试在通过单击按钮启动的控制台中显示文本。我想我需要输入控制台的路径，我把问号放在Process.Start（“????”）。如何找到控制台路径？

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Process.Start("????");
        Console.WriteLine("Adam");
        Console.Read();
    }
}

以下是一个很好的示例：http://cboard.cprogramming.com/csharp-programming/130369-command-prompt-use-within-csharp-class-file.html#post973331

代码：

string returnvalue = "";

// Starts the new process as command prompt
ProcessStartInfo info = new ProcessStartInfo("cmd.exe");
info.UseShellExecute = false;
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
// Makes it so the command prompt window does appear
info.CreateNoWindow = true;

using (Process process = Process.Start(info))
{
    StreamWriter sw = process.StandardInput;
    StreamReader sr = process.StandardOutput;

    // This for loop could be used if you had a string[] commands where each string in commands
    // is it's own command to write to the prompt. I chose to hardcode mine in.
    //foreach (string command in commands)
    //{
    //    sw.WriteLine(command);
    //}
    sw.WriteLine("cd " + processPath);
    sw.WriteLine("perl process.pl");

    sw.Close();
    returnvalue = sr.ReadToEnd();
}

return returnvalue;

您需要执行应用程序cmd.exe。但是使用Controle.WriteLine将不会写入该控制台，并且Console.ReadLine将无法从该控制台读取。您必须重定向流程的输入和输出流，以便与启动的控制台应用程序进行交互。

这是一个包装AllocConsole（）的类：

/// <summary>Simple class to allow creation and destruction of Consoles.</summary>

public static class ConsoleManager
{
    #region public static Methods

    /// <summary>
    /// Creates a console output window, if one doesn't already exist.
    /// This window will receive all outputs from System.Console.Write()
    /// </summary>
    /// <returns>
    /// 0 if successful, else the Windows API error code from Marshal.GetLastWin32Error()
    /// </returns>
    /// <remarks>See the AllocConsole() function in the Windows API for full details.</remarks>

    public static int Create()
    {
        if (AllocConsole())
        {
            return 0;
        }
        else
        {
            return Marshal.GetLastWin32Error();
        }
    }

    /// <summary>
    /// Destroys the console window, if it exists.
    /// </summary>
    /// <returns>
    /// 0 if successful, else the Windows API error code from Marshal.GetLastWin32Error()
    /// </returns>
    /// <remarks>See the FreeConsole() function in the Windows API for full details.</remarks>

    public static int Destroy()
    {
        if (FreeConsole())
        {
            return 0;
        }
        else
        {
            return Marshal.GetLastWin32Error();
        }
    }

    #endregion  // public static Methods

    #region Private PInvokes

    [SuppressMessage( "Microsoft.Security", "CA2118:ReviewSuppressUnmanagedCodeSecurityUsage" ), SuppressUnmanagedCodeSecurity]
    [DllImport("kernel32.dll",SetLastError=true)]
    [return: MarshalAs( UnmanagedType.Bool )]
    static extern bool AllocConsole();


    [SuppressMessage( "Microsoft.Security", "CA2118:ReviewSuppressUnmanagedCodeSecurityUsage" ), SuppressUnmanagedCodeSecurity]
    [DllImport("kernel32.dll",SetLastError=true)]
    [return: MarshalAs( UnmanagedType.Bool )]
    static extern bool FreeConsole();

    #endregion  // Private PInvokes
}

只需调用ConsoleManager.Create（），然后就可以执行Console.WriteLine（）。

您应该有两个项目。第一个是具有所有功能的 Windows应用程序，另一个应该是类型为“控制台应用程序”的项目。然后，您应该在按钮的单击事件中执行第二个项目（您的控制台application.exe）的输出。

问题是你没有那种方式调用“Console.WriteLine”。简单地说它不起作用。我的建议是使用.NET Remoting在两个不同的项目之间完成工作。

.NET Remoting IPC：

希望它有所帮助！

您需要做的是从Windows API获取控制台。这将创建一个可以输出和读取的控制台应用程序的新实例。

public partial class Form1 : Form
{
    [DllImport("kernel32.dll", SetLastError = true)]
    internal static extern int AllocConsole();

    [DllImport("kernel32.dll", SetLastError = true)]
    internal static extern int FreeConsole();

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        int alloc = AllocConsole(); // Grab a new console to write to
        if (alloc != 1)
        {
            MessageBox.Show("Failed");
            return;
            }
        Console.WriteLine("test");

        Console.WriteLine("Adam");
        string input = Console.ReadLine();
        Console.WriteLine(input);
        // Do other funky stuff

        // When done
        FreeConsole();
    }
}

C＃中的控制台路径是什么？
