[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] internal struct InputRecord { internal short eventType; internal KeyEventRecord keyEvent; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] internal struct KeyEventRecord { internal bool keyDown; internal short repeatCount; internal short virtualKeyCode; internal short virtualScanCode; internal char uChar; internal int controlKeyState; } [DllImport("kernel32.dll", SetLastError = true)] internal static extern bool PeekConsoleInput(IntPtr hConsoleInput, out InputRecord buffer, int numInputRecords_UseOne, out int numEventsRead); [DllImport("kernel32.dll", SetLastError = true)] internal static extern bool ReadConsoleInput(IntPtr hConsoleInput, out InputRecord buffer, int numInputRecords_UseOne, out int numEventsRead); [DllImport("kernel32.dll", SetLastError = true)] internal static extern IntPtr GetStdHandle(int nStdHandle); static Nullable PeekConsoleEvent() { InputRecord ir; int num; if (!PeekConsoleInput(GetStdHandle(-10), out ir, 1, out num)) { //TODO process error } if (num != 0) return ir; return null; } static InputRecord ReadConsoleInput() { InputRecord ir; int num; if (!ReadConsoleInput(GetStdHandle(-10), out ir, 1, out num)) { //TODO process error } return ir; } static bool PeekEscapeKey() { for (; ; ) { var ev = PeekConsoleEvent(); if (ev == null) { Thread.Sleep(10); continue; } if (ev.Value.eventType == 1 && ev.Value.keyEvent.keyDown && ev.Value.keyEvent.virtualKeyCode == 27) { ReadConsoleInput(); return true; } if (ev.Value.eventType == 1 && ev.Value.keyEvent.keyDown) return false; ReadConsoleInput(); } } 

用法示例：

  for (; ; ) { Console.Write("?"); if (PeekEscapeKey()) { Console.WriteLine("esc"); continue; } Console.Write(">"); var line = Console.ReadLine(); Console.WriteLine(line); } 

要窥视，您必须使用TextReader.Peek。 要在控制台中使用它，您可以使用Console.In.Peek() 。 要使用您正在考虑的代码：

 if(Console.In.Peek() != "x1B") // 0x1B is the Escape Key { string input = Console.ReadLine(); .... } 

这应该工作。 我没有测试过，但似乎没错。

或者用于比@ user823682稍微不那么优雅的方法
