C# Console.TreatControlCAsInput用法及代碼示例

Console.TreatControlCAsInput 屬性用於獲取或設置一個值，該值指示 Control 修飾鍵和 C 控製台鍵 (Ctrl+C) 的組合是被視為普通輸入還是被操作係統處理的中斷。

用法:

public static bool TreatControlCAsInput { get; set; }

屬性值：如果 Ctrl+C 被視為普通輸入，則此屬性返回 true。否則為 false，表示如果輸入是 Ctrl+C，則程序終止。

Exception:如果程序無法獲取或設置控製台輸入緩衝區的輸入模式，則此屬性將給出 IOException。

以下示例程序旨在說明上述屬性的使用：

範例1：


// C# program to illustrate the use of
// Console.TreatControlCAsInput Property
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        ConsoleKeyInfo c;
  
        // Prevent program from terminating 
        // if CTL+C is pressed.
        Console.TreatControlCAsInput = true;
  
        Console.WriteLine("Press any key with combination of CTL, "+
                    "ALT, and SHIFT or Press the Esc to quit:\n");
  
        do {
  
            c = Console.ReadKey();
            Console.Write(" - pressed key is ");
  
            // only prints the pressed keys
            Console.WriteLine(c.Key.ToString());
  
          // condition for Exit
        } while (c.Key != ConsoleKey.Escape);
          
    }
}

輸出：

範例2：


// C# program to illustrate the use of
// Console.TreatControlCAsInput Property
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        ConsoleKeyInfo c;
  
        // Prevent program from terminating 
        // if CTL+C is pressed.
        Console.TreatControlCAsInput = true;
  
        Console.WriteLine("Press any key with combination of CTL, "+
                     "ALT, and SHIFT or Press the Esc to quit:\n");
  
        do {
  
            c = Console.ReadKey();
            Console.Write("pressed key is ");
  
            // conditions-
            if ((c.Modifiers & ConsoleModifiers.Shift) != 0)
                Console.Write("SHIFT + ");
  
            if ((c.Modifiers & ConsoleModifiers.Control) != 0)
                Console.Write("CTL + ");
  
            if ((c.Modifiers & ConsoleModifiers.Alt) != 0)
                Console.Write("ALT + ");
  
            // prints the pressed keys
            Console.WriteLine(c.Key.ToString());
             
          // condition for Exit
        } while (c.Key != ConsoleKey.Escape);
          
    }
}

輸出：

假的時候


using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        ConsoleKeyInfo c;
  
        // Prevent program from terminating 
        // if CTL+C is pressed.
        Console.TreatControlCAsInput = false;
  
        Console.WriteLine("Press any key with combination of CTL,"+
                  " ALT, and SHIFT or Press the Esc to quit:\n");
  
        do {
            c = Console.ReadKey();
            Console.Write(" - pressed key is ");
  
            // only prints the pressed keys
            Console.WriteLine(c.Key.ToString());
              
          // condition for Exit
        } while (c.Key != ConsoleKey.Escape);
          
    }
}

輸出：

Press any key with combination of CTL, ALT, and SHIFT or Press the Esc to quit:

a - pressed key is A
b - pressed key is B
g - pressed key is G

// Here after these input we press Ctrl+C, 
// then the program is terminated.
