WinForm使用Console窗口输出Log

 使用AllocConsole()和FreeConsole()

代码简单，做个备忘，如下：

 

 [DllImport("kernel32.dll")]
  public static extern Boolean AllocConsole();
  [DllImport("kernel32.dll")]
  public static extern Boolean FreeConsole();

  /// <summary>
  /// 应用程序的主入口点。
  /// </summary>
  [STAThread]
  static void Main()
  {

#if DEBUG
   AllocConsole();
#endif

   Application.EnableVisualStyles();
   Application.SetCompatibleTextRenderingDefault(false);
   Application.Run(new Form1());

   FreeConsole();
  }

 

使用AllocConsole()开启控制台窗口后，就可以直接用Console.Write()输出log到窗口了，还可以定制颜色

public Form1()
  {
   InitializeComponent();

   Console.ForegroundColor = ConsoleColor.Red;
   Console.Write("Error:\t");
   Console.ForegroundColor = ConsoleColor.Gray;
   Console.WriteLine("this is an error log");

   Console.ForegroundColor = ConsoleColor.Yellow;
   Console.Write("Warn:\t");
   Console.ForegroundColor = ConsoleColor.Gray;
   Console.WriteLine("this is a warn log");

   Console.ForegroundColor = ConsoleColor.Green;
   Console.Write("Normal:\t");
   Console.ForegroundColor = ConsoleColor.Gray;
   Console.WriteLine("this is a normal log");
  }
