刚刚碰到了下面描述的问题。如果 "Console.TreatControlCAsInput = true;"，你必须在ReadLine()上按两次[enter]。
我在下面写了一些演示代码。我猜测这段代码演示了.NET 4框架中的一个bug是正确的吗？
Console.Write("Test 1: Console.TreatControlCAsInput = false\nType \"hello\": ");
{
string readline = Console.ReadLine(); // type "hello" [enter].
Console.WriteLine("You typed: {0}", readline);
// Prints "hello".
}
Console.Write("Test 2: Console.TreatControlCAsInput = true\nType \"hello\": ");
Console.TreatControlCAsInput = true;
{
string readline = Console.ReadLine(); // type "hello" [enter].
Console.WriteLine("You typed: {0}", readline);
// Should print "hello" - but instead, you have to press [enter]
// *twice* to complete the ReadLine() command, and it adds a "\r"
// rather than a "\n" to the output (so it overwrites the original line)
}
// This bug is a fatal error, because it makes all ReadLine() commands unusable.
Console.Write("[any key to exit]");
Console.ReadKey();
