I am writing a console application and I would like to put a "Press any key..." message once the program is done executing. Currently, when it executes it returns to the prompt. I have tried console.read and console.readlin e but they both require an <Enter> key to be hit. Any suggestions?

You have to use P/Invoke for this to call SetConsoleMode to turn off
ENABLE_LINE_INP UT and ENABLE_ECHO_INP UT. Here is a little program that
I use to grab key values for a batch file menu... It is pretty quick
and dirty, but it does the job :)
using System;
using System.Componen tModel;
using System.Runtime. InteropServices ;
namespace GetKey
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class KeyGrabber
{
// constant values for use with the console api
private const uint STD_INPUT_HANDL E = unchecked((uint ) -10);
private const uint ENABLE_LINE_INP UT = 0x0002;
private const uint ENABLE_ECHO_INP UT = 0x0004;
private static readonly IntPtr INVALID_HANDLE_ VALUE = new
IntPtr(-1);
// console functions
[DllImport("kern el32", ExactSpelling=t rue, SetLastError=tr ue)]
private static extern IntPtr GetStdHandle (
uint nStdHandle);
[DllImport("kern el32", ExactSpelling=t rue, SetLastError=tr ue)]
private static extern bool GetConsoleMode (
IntPtr hConsoleHandle,
out uint lpMode);
[DllImport("kern el32", ExactSpelling=t rue, SetLastError=tr ue)]
private static extern bool SetConsoleMode(
IntPtr hConsoleHandle,
uint dwMode);
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static int Main(string[] args)
{
int ret = 0;
string prompt = (args.Length != 0 ? args[0] : string.Empty);
IntPtr stdin = GetStdHandle(ST D_INPUT_HANDLE) ;
if (stdin != INVALID_HANDLE_ VALUE)
{
uint oldMode;
if (GetConsoleMode (stdin, out oldMode))
{
uint newMode = (oldMode & (~(ENABLE_LINE_ INPUT |
ENABLE_ECHO_INP UT)));
if (SetConsoleMode (stdin, newMode))
{
Console.Write(p rompt);
ret = Console.Read();
Console.WriteLi ne();
if (!SetConsoleMod e(stdin, oldMode))
{
ret = -1;
}
}
else
{
ret = -1;
}
}
else
{
ret = -1;
}
}
else
{
ret = -1;
}
return ret;
}
}
}
