So i have this code in a .NET 2.0 console app:

[DllImport('kernel32.dll')] private static extern bool SetConsoleTextAttribute(IntPtr hConsoleOutput,      int wAttributes);  [DllImport('kernel32.dll')] private  static extern IntPtr GetStdHandle(uint nStdHandle);  private static readonly IntPtr hConsole;

And then in a method i have this:

const uint STD_OUTPUT_HANDLE = 0xfffffff5; hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

And when i try to execute this app through Mono on a clean install of Ubuntu 8.10 i get this exception:

Unhandled Exception: System.TypeInitializationException:  An exception was thrown by the type initializer for      IMAPShell.Helpers.ColorConsole --->          System.EntryPointNotFoundException: GetStdHandle   at (wrapper managed-to-native) IMAPShell.Helpers.ColorConsole:GetStdHandle (uint)   at IMAPShell.Helpers.ColorConsole..cctor () [0x00000] --- End of inner exception stack trace ---    at IMAPShell.Program.PrintWelcome () [0x00000]    at IMAPShell.Program.Main (System.String[] args) [0x00000]

Basically what i am doing is changing the color of the console output. I wrote this handy method that you can embed color codes into a string of text and it will parse out the codes and change the color of the output until it hits another color code.

It works great on windows, and i would like it to work the same under Mono. Does anyone have any suggestions as to what i can try to get it to work under both OSes?

  1. Can’t you use Console.BackgroundColor and Console.Foreground color instead? This way you won’t need to go through the interop layer.
