C＃中的控制台路徑是什么？

Question

我試圖在通過單擊按鈕啟動的控制台中顯示文本。 我想我需要輸入控制台的路徑，在該路徑中我已經打上了問號Process.Start（“ ????”）。 如何找到控制台路徑？

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

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

Answer 1

這是一個很好的示例，該怎么做： http : //cboard.cprogramming.com/csharp-programming/130369-command-prompt-use-within-csharp-class-file.html#post973331

碼：

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;

您需要執行應用程序cmd.exe 。 但是使用Controle.WriteLine不會寫入該控制台，而Console.ReadLine不會從該控制台讀取。 您必須重定向流程的輸入和輸出流，以與啟動的控制台應用程序進行交互。

這是包裝AllocConsole（）的類：

/// <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
}

只需調用ConsoleManager.Create（），然后您就可以執行Console.WriteLine（）。

Answer 4

您應該有兩個項目。 第一個是具有所有功能的Windows應用程序 ，另一個應該是類型為“ 控制台應用程序 ”的項目。 然后，您應該在按鈕的click事件中執行第二個項目（您的Console application.exe）的輸出。

問題是您沒有那種那樣調用“ Console.WriteLine ”的東西。 簡直是行不通的。 我的建議是使用.NET Remoting在兩個不同的項目之間進行工作。

.NET遠程IPC：

希望能幫助到你！

您需要做的是從Windows API中獲取控制台。 這將創建一個控制台應用程序的新實例，該實例可以輸出和讀取等。

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();
    }
}
