为什么我不能在C＃三元表达式中使用break？ [英] Why can't I use break in a C# ternary expression?

问题描述

我正在尝试在while循环中将if else子句转换为三元数，但是它不允许我在问号后休息，将错误指向中断作为无效表达式。

I am trying to convert the if else clause to a ternary within a while loop, however it's not allowing me to have a break after the question mark, pointing an error at the break as an invalid expression.

如何将这种简单的方法转换成三元的方法。

How would I go about turning this simple if else into a ternary like so.

while (true)
{
    Console.WriteLine("Enter 3 words seperated by spaces: ");
    var input = Console.ReadLine();
    //input == "" ? break : ConvertToPascal(input);
    if (input == "")
        break;
    else
        ConvertToPascal(input);
    }
}

推荐答案

它使用三元运算符是不可能的，但是您可以按如下所示简化代码结构：

It isn't possible using the ternary operator, but you can simplify your code structure as follows:

string input;
do {
    Console.WriteLine("Enter 3 words seperated by spaces: ");
    input = Console.ReadLine();
    if (input != "") {
        ConvertToPascal(input);
    }
} while(input != "");
