在kernel32.dll導(dǎo)入控制臺(tái)的兩個(gè)方法：AllocConsole()+FreeConsole()

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

static class Program
    {
        /// <summary>
        /// 應(yīng)用程序的主入口點(diǎn)。
        /// </summary>

        [DllImport("kernel32.dll")]
        static extern bool FreeConsole();
        [DllImport("kernel32.dll")]
        public static extern bool AllocConsole();
        [STAThread]
        static void Main()
        {
            AllocConsole();//調(diào)用系統(tǒng)API，調(diào)用控制臺(tái)窗口

            Console.WriteLine("Hello World");
            Console.ReadKey();

            FreeConsole();//釋放控制臺(tái)

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            SqlServerString.SqlConnectString = "LTKDB";
            Application.Run(new Form1());
        }
    }
