c# 启动控制台

namespace 测试使用
{     public partial class Form1 : Form { [System.Runtime.InteropServices.DllImport("kernel32.dll", SetLastError = true)] [return: System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.Bool)] static extern bool AllocConsole(); [System.Runtime.InteropServices.DllImport("Kernel32")] public static extern void FreeConsole(); public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { AllocConsole();   //开启控制台 } }
}

输出一

通常的代码段： Console.WriteLine(“测试”);

效果显示：

输出二：

创建方法类来进行输出

           Shell.WriteLine("注意：启动程序...");
            Shell.WriteLine("\tWritten by wuming");
            Shell.WriteLine("{0}：{1}", "警告", "这是一条警告信息。");
            Shell.WriteLine("{0}：{1}", "错误", "这是一条错误信息！");
            Shell.WriteLine("{0}：{1}", "注意", "这是一条需要的注意信息。");
            Shell.WriteLine("");

           Shell.WriteLine("测试",ConsoleColor.DarkRed);

  static class Shell
    { /// <summary>   /// 输出信息   /// </summary>   /// <param name="format"></param>   /// <param name="args"></param>   public static void WriteLine(string message, ConsoleColor GetConsoleColor) { Console.ForegroundColor = GetConsoleColor; Console.WriteLine(@"[{0}]{1}", DateTimeOffset.Now, message); }         /// <summary>  
        /// 输出信息  
        /// </summary>  
        /// <param name="format"></param>  
        /// <param name="args"></param>  
        public static void WriteLine(string format, params object[] args)
        {
            WriteLine(string.Format(format, args));
        }

        /// <summary>  
        /// 输出信息  
        /// </summary>  
        /// <param name="output"></param>  
        public static void WriteLine(string output)
        {
            Console.ForegroundColor = GetConsoleColor(output);
            Console.WriteLine(@"[{0}]{1}", DateTimeOffset.Now, output);
        }

        /// <summary>

        /// </summary>  
        /// <param name="output"></param>  
        /// <returns></returns>  
        private static ConsoleColor GetConsoleColor(string output)
        {
            if (output.StartsWith("警告")) return ConsoleColor.Yellow;
            if (output.StartsWith("错误")) return ConsoleColor.Red;
            if (output.StartsWith("注意")) return ConsoleColor.Green;
            return ConsoleColor.Gray;
        }
    }
