我正在尝试添加一种方法来为用户评分我的测验答案，并在测验结束时显示。试图找出一个简单的方法，我不必完全重做我当前的代码，因为我是一个业余编码器充其量。关于这个问题的任何建议将不胜感激。这是我当前代码的示例，以便您可以看到我正在使用的内容。我只包括前三个问题，但总共有10个问题：
using System;
namespace Quiz
{
class MultipleChoiceQuiz
{
public static void CurrentQuestion(string correctAnswer)
{
do
{
string userAnswer = Console.ReadLine();
if (userAnswer != "A" && userAnswer != "B" && userAnswer != "C" && userAnswer != "D")
{
Console.WriteLine("\nError - Not a Valid Input - Please Enter Valid Input");
}
else
{
if (userAnswer == correctAnswer)
{
Console.WriteLine("\nThat is correct!");
break;
}
else if (userAnswer != correctAnswer)
{
Console.WriteLine("\nSorry, that is incorrect.");
break;
}
}
}
while (true);
}
public static void Questions()
{
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Please enter your first name: ");
string firstName = Console.ReadLine();
Console.WriteLine("\nWelcome to the HC-130J Power-On Quiz " + firstName + ".\n");
Console.WriteLine("Using the keyboard, please submit answers by using the \'ENTER\' key.\n");
Console.WriteLine("Please submit answers in CAPITAL letter form only.\n");
Console.WriteLine("Ready to begin " + firstName + "? Hit the \'ENTER\' key now...");
Console.ReadLine();
Console.Clear();
//Question 1
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Question 1 - What position does the ramp contol knob need to be in? " +
"\n\nA. 3N \nB. 1 \nC. 6N \nD. A or C \n\nWhat is your answer " + firstName + "?");
CurrentQuestion("D");
Console.Write("\nPress \'ENTER\' to continue...");
Console.ReadLine();
Console.Clear();
//Question 2
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Question 2 - After power is applied to the aircraft, the battery needs to be turned off? " +
"\n\nA. True \nB. False \n\nWhat is your answer " + firstName + "?");
CurrentQuestion("A");
Console.Write("\n");
Console.Write("\nPress \'ENTER\' to continue...");
Console.ReadLine();
Console.Clear();
//Question 3
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Question 3 - Above what temperature does air condition need to be applied to the aircraft while power is applied? " +
"\n\nA. 75 degrees Fahrenheit \nB. 100 degrees Fahrenheit \nC. 95 degrees Fahrenheit \nD. 85 degrees Fahrenheit \n\nWhat is your answer "
+ firstName + "?");
CurrentQuestion("C");
Console.Write("\n");
Console.Write("\nPress \'ENTER\' to continue...");
Console.ReadLine();
Console.Clear();
答案 0 :(得分：0)
在类中添加一个静态int，如果在中断之前 CurrentQuestion 的答案是正确的，则添加一个静态int。
编辑：以下是一个例子：
using System;
namespace Quiz
{
class MultipleChoiceQuiz
{
static int correct = 0; // this will hold the correct answers
static int questions = 0; // this will hold the amount of questions
public static void CurrentQuestion(string correctAnswer)
{
questions++;//this will add 1 when CurrentQuestion is called
do
{
string userAnswer = Console.ReadLine();
if (userAnswer != "A" && userAnswer != "B" && userAnswer != "C" && userAnswer != "D")
{
Console.WriteLine("\nError - Not a Valid Input - Please Enter Valid Input");
}
else
{
if (userAnswer == correctAnswer)
{
Console.WriteLine("\nThat is correct!");
correct++;//this will add 1 to correct when you answer correctly
break;
}
else if (userAnswer != correctAnswer)
{
Console.WriteLine("\nSorry, that is incorrect.");
break;
}
}
}
while (true);
}
public static void Questions()
{
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Please enter your first name: ");
string firstName = Console.ReadLine();
Console.WriteLine("\nWelcome to the HC-130J Power-On Quiz " + firstName + ".\n");
Console.WriteLine("Using the keyboard, please submit answers by using the \'ENTER\' key.\n");
Console.WriteLine("Please submit answers in CAPITAL letter form only.\n");
Console.WriteLine("Ready to begin " + firstName + "? Hit the \'ENTER\' key now...");
Console.ReadLine();
Console.Clear();
//Question 1
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Question 1 - What position does the ramp contol knob need to be in? " +
"\n\nA. 3N \nB. 1 \nC. 6N \nD. A or C \n\nWhat is your answer " + firstName + "?");
CurrentQuestion("D");
Console.Write("\nPress \'ENTER\' to continue...");
Console.ReadLine();
Console.Clear();
//Question 2
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Question 2 - After power is applied to the aircraft, the battery needs to be turned off? " +
"\n\nA. True \nB. False \n\nWhat is your answer " + firstName + "?");
CurrentQuestion("A");
Console.Write("\n");
Console.Write("\nPress \'ENTER\' to continue...");
Console.ReadLine();
Console.Clear();
//Question 3
Console.WriteLine("Chad Mitchell - ENGR 115 - USAF HC130J Power On Quiz\n");
Console.WriteLine("Question 3 - Above what temperature does air condition need to be applied to the aircraft while power is applied? " +
"\n\nA. 75 degrees Fahrenheit \nB. 100 degrees Fahrenheit \nC. 95 degrees Fahrenheit \nD. 85 degrees Fahrenheit \n\nWhat is your answer "
+ firstName + "?");
CurrentQuestion("C");
Console.Write("\n");
Console.Write("\nPress \'ENTER\' to continue...");
Console.ReadLine();
Console.Clear();
//Score
Console.WriteLine("You got " + correct + " out of " + questions + " correctly!");
}
}
}
答案 1 :(得分：0)
替换：
public static void CurrentQuestion(string correctAnswer)
与
public static int CurrentQuestion(string correctAnswer)
如果答案是正确的，则返回1，否则返回0。
在score方法中添加Questions变量：
public static void Questions()
{
int score = 0;
将CurrentQuestion(Answer)来电更改为：
score += CurrentQuestion(...
最后显示score。
