C＃为什么它跳过我到Console.ReadLine（）？ [英] C# why is it skipping my console.readline()?
问题描述
所以程序工作正常，但由于某些原因，在第二次通过，它跳过到Console.ReadLine（）提示干脆。我通过调试运行，并确认它是不是循环问题，因为它实际上是在进入方法，显示的WriteLine然后完全跳过了的ReadLine，从而返回一个空白返回主（）使其退出。真见鬼？任何想法？

这是因为在你的 Console.Read（）通话 DisplayResults 方法。它一般只读取一个字符。如果preSS ENTER（实际上是2个字符组合 - 回车换行）在 Console.Read（）它只是变得回车符和行饲料到达你的下一个控制台读法 - 到Console.ReadLine（）在 GetInput（）方法。因为换行符也是一个linux输入字符，到Console.ReadLine（）把它读成一条线。
So the program is working correctly, but for some reason, on the second time through, it is skipping the Console.ReadLine() prompt altogether. I ran through debug and confirmed that it isn't a loop problem as it is actually entering the method, displaying the WriteLine then completely skipping over the ReadLine, thus returning a blank back to Main() causing it to exit. What the deuce? Any ideas?
here is the code.
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace LAB4B
{
class Program
{
static void Main(string[] args)
{
string inString;
ArrayList translatedPhrase = new ArrayList();
DisplayInfo();
GetInput(out inString);
do
{
GetTranslation(inString, translatedPhrase);
DisplayResults(inString, translatedPhrase);
GetInput(out inString);
} while (inString != "");
}
static void DisplayInfo()
{
Console.WriteLine("*** You will be prompted to enter a string of ***");
Console.WriteLine("*** words. The string will be converted into ***");
Console.WriteLine("*** Pig Latin and the results displayed. ***");
Console.WriteLine("*** Enter as many strings as you would like. ***");
}
static void GetInput(out string words)
{
Console.Write("\n\nEnter a group of words or ENTER to quit: ");
words = Console.ReadLine();
}
static void GetTranslation(string originalPhrase, ArrayList translatedPhrase)
{
int wordLength;
string[] splitPhrase = originalPhrase.Split();
foreach (string word in splitPhrase)
{
wordLength = word.Length;
translatedPhrase.Add(word.Substring(1, wordLength - 1) + word.Substring(0, 1) + "ay");
}
}
static void DisplayResults(string originalString, ArrayList translatedString)
{
Console.WriteLine("\n\nOriginal words: {0}", originalString);
Console.Write("New Words: ");
foreach (string word in translatedString)
{
Console.Write("{0} ", word);
}
Console.Read();
}
}
}
It's because of your Console.Read() call in DisplayResults method. It generally reads just one character. If you press ENTER (which is actually combination of 2 characters - carriage return and line feed) on Console.Read() it only gets carriage return character, and line feed gets to your next console reading method - Console.ReadLine() in GetInput() method. Since line feed character is also a linux ENTER character, Console.ReadLine() reads it as one line.
