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> /// 根据输出文本选择控制台文字颜色 /// </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;}}
