I have written the following code and would like to know if it could be
optimised. In particular, I''m reading the user input for the operand into
variable strOperand, and rather than use the IF statement to determine which
operand to use, I''d like to use the variable contents
e.g. dblAnswer = dblFirstNo strOperand dblSecondNo
Also, the While clause at the end...ideally, I would like to write something
like
while (strMore != "y" and strMore !="n")
but I don''t know how to do this.
Any help appreciated.

推荐答案
它在我看来，你希望用户按照说明操作，并且
不会打字，因为你的代码要求用户输入一个数字，然后
解析字符串输入到一个数字，而不检查它是否是一个
数字。如果用户输入非数字输入，您的应用
将崩溃。你需要实现一些检查。例如，您可以使用
System.Double.TryParse来检查输入。例如：
bool isNumeric = false;
double dblFirstNo;
字符串输入;
while（！isNumeric）
{
input = Console.ReadLine（）;
isNumeric = Double.TryParse（输入，输出） dblFirstNo）;
if（！isNumeric）
Console.WriteLine（"你没输入数字。请输入一个数字
" ;）;
}

新闻：8F ************************* ********* @ microsof t.com ...
It looks to me like you''re expecting the user to follow instructions, and
not make any typos, as your code asks the user to enter a number, and then
parses the string input to a number without checking to see if it is a
number first. In the event that a user enters a non-numeric input, your app
will crash. You need to implement some checking. For example, you could use
System.Double.TryParse to check the input first. Example:
bool isNumeric = false;
double dblFirstNo;
string input;
while (!isNumeric)
{
input = Console.ReadLine();
isNumeric = Double.TryParse(input, out dblFirstNo);
if (!isNumeric)
Console.WriteLine("You did not enter a number. Please enter a number
");
}

比利，
我冒昧地重写你的代码，把它分成几个小b * b小方法。这使代码更容易遵循。拇指规则是，如果你不能同时在屏幕上显示整个方法，那么
方法太长了。如果您输入文本或
无效的操作数，您的代码将崩溃。此外，如果/ if if，交换机比
更快更容易维护。默认情况永远不会发生，但是需要，因为编译器
不知道（或者在切换后放置返回）。而不是
ReadLine我使用ReadKey作为Y / N并隐藏结果。

Hi Billy,
I''ve taken the liberty to rewrite your code, splitting it into several
smaller methods. This makes the code easier to follow. A thumb rule is,
if you can''t se the entire method on the screen at the same time, the
method is too long. Your code would have crashed if you entered text or
an invalid operand. Also, a switch is faster and easier to maintain than
if/else if. Default will never happen, but is needed since the compiler
does not know that (or put the return after the switch). Instead of
ReadLine I used a ReadKey for the Y/N and hide the result.
static void Main(string[] args)
{
do
{
Calculate();
}
while (DoContinue());
}
static void Calculate()
{
//declare the variables to be used with default values
double dblFirstNo = 0, dblSecondNo = 0, dblAnswer = 0;
string strOperand = "*";
//get the first number
Console.WriteLine("Please enter a number ");
dblFirstNo = ReadNumber();
//ask what they want to do with the numbers
Console.WriteLine("Please enter an operand ( * / + - )");
strOperand = ReadOperand();
//get the next number
Console.WriteLine("Please enter another number");
dblSecondNo = ReadNumber();
// get the answer
dblAnswer = GetAnswer(dblFirstNo, strOperand, dblSecondNo);
//output the sum and the answer
Console.WriteLine("{0} {1} {2} = {3}", dblFirstNo, strOperand,
dblSecondNo, dblAnswer);
}
static string ReadOperand()
{
string operand = Console.ReadLine();
while (operand != "*" && operand != "/" && operand !="+" &&
operand != "-")
{
Console.WriteLine("Please enter a valid operand");
operand = Console.ReadLine();
}
return operand;
}
static double ReadNumber()
{
double result;
string value = Console.ReadLine();
while (!Double.TryParse(value, out result))
{
Console.WriteLine("Please enter a valid number");
value = Console.ReadLine();
}

}

secondNumber)

switch (operand)
{
case "*":
return firstNumber * secondNumber;
case "/":

case "+":

case "-":

一个非常合理的努力。我已经改写了，你会注意到我已经没有回答你关于while（strMore！=" y和strMore
）的问题。 ！= QUOT; N"）"所以我会在这里做。
你会把它写成
do
{
stuff
} while（aString！=" y"& aString！=" n"）;使用| （管道）for或。
这是我的努力。我把它放在一个函数中，并为
程序控件添加了一个枚举。该函数是静态的，因此您只需将其粘贴到您的应用程序中，然后使用Calc（）调用它;注意换行:)
私人enum PlayAgainOptions
{
无效，playAgain，exitGame
}
private static void Calc（）
{
double firstNo，secondNo，result = 0;
字符串操作数;
PlayAgainOptions playAgain = PlayAgainOptions.invalid;
do
{
System.Console.WriteLine（" Please enter a number）;
firstNo = double.Parse（System.Console.ReadLine（））;
System.Console.WriteLine（" Please enter another number"）;
secondNo = double.Parse（System.Console.ReadLine（））;
System.Console.WriteLine（" Please enter a operandrand（* / + - ）"）;
operand = System.Console.ReadLine（）;
开关（操作数）
{
case" *"：
result = firstNo * secondNo;
休息;
case" /"：
result = firstNo / secondNo;
休息;
case" +"：
result = firstNo + secondNo;
break;
case" - "：
result = firstNo - secondNo;
break;
默认值：
//以上都不是！
休息;
}
//在答案中包含操作数
System.Console.WriteLine（" {0} {1} {2} = {3}"，firstNo，operand，
secondNo，result）;
do
{
System.Console.WriteLine（"你想输入更多？ （y / n）"）;
//转换为小写，因此我们也捕获了Y或N.
switch（System.Console.ReadLine（）。 ToLower（））
{
case" y"：
playAgain = PlayAgainOptions.playAgain;
break ;
case" n"：
playAgain = PlayAgainOptions.exitGame;
break;
默认值：
playAgain = PlayAgainOptions.invalid;
休息;
}
} while（PlayAgainOptions.invalid == playAgain） ;
} while（PlayAgainOptions.playAgain == playAgain）;
}
}

A perfectly reasonable effort. I''ve rewritten it and you''ll notice I''ve
not answered your question about "while (strMore !="y" and strMore
!="n")" so I''ll do that here.
you would write it as
do
{
stuff
}while(aString != "y" & aString != "n"); use | (pipe) for or.
Here''s my effort. I''ve bunged it in a function and added an enum for
program control. The function is static so you can just paste it into
your app and call it with Calc(); Watch for line wrap :)
private enum PlayAgainOptions
{
invalid, playAgain, exitGame
}
private static void Calc()
{
double firstNo, secondNo, result = 0;
string operand;
PlayAgainOptions playAgain = PlayAgainOptions.invalid;
do
{

firstNo = double.Parse(System.Console.ReadLine());
System.Console.WriteLine("Please enter another number");
secondNo = double.Parse(System.Console.ReadLine());
System.Console.WriteLine("Please enter an operand ( * / + - )");
operand = System.Console.ReadLine();
switch(operand)
{
case "*":
result = firstNo * secondNo;
break;
case "/":
result = firstNo / secondNo;
break;
case "+":
result = firstNo + secondNo;
break;
case "-":
result = firstNo - secondNo;
break;
default:
// None of the above!
break;
}
// include the operand in the answer
System.Console.WriteLine("{0} {1} {2} = {3}",firstNo, operand,
secondNo, result);
do
{
System.Console.WriteLine("Do you want to enter more? (y/n)");
//convert to lowercase so we capture a Y or N as well.
switch (System.Console.ReadLine().ToLower())
{
case "y":
playAgain = PlayAgainOptions.playAgain;
break;
case "n":
playAgain = PlayAgainOptions.exitGame;
break;
default:
playAgain = PlayAgainOptions.invalid;
break;
}
} while (PlayAgainOptions.invalid == playAgain);
}while(PlayAgainOptions.playAgain == playAgain);
