c#如何嵌套第三方程序

C# (or other programming languages also) allows to use a conditional/ternary operator within another conditional/ternary operator.

C＃(或其他编程语言)还允许在另一个条件/三元运算符中使用条件/三元运算符。

Syntax:

句法：

    (logical_test1) ?
((logical_test2)? True_block : false_block) :
false_block_outer;

If logical_test1 is true then logical_test2 will be checked, if it is true then "true_block" executes, else "false_block" executes, and if logical_test1 is false then "false_block_outer" will be executed.

如果logical_test1为true，则将检查logical_test2 ，如果为true，则将执行“ true_block” ，否则将执行“ false_block” ，如果logical_test1为false，则将执行“ false_block_outer” 。

Note: Inner conditional operator can be used in any block as per the requirement.

注意：根据条件，可以在任何块中使用内部条件运算符。

嵌套条件/三元运算符的C＃示例 (C# example for nested conditional/ternary operator)

Here, we are asking to input three numbers and finding the largest number.

在这里，我们要求输入三个数字并找到最大的数字。

// C# program to demonstrate example of
// nested conditional operator
using System;
using System.IO;
using System.Text;
namespace IncludeHelp
{class Test
{// Main Method
static void Main(string[] args)
{//finding largest of three  numbers
int a;
int b;
int c;
//input numbers
Console.Write("Enter first number : ");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter second number: ");
b = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter third number : ");
c = Convert.ToInt32(Console.ReadLine());
//finding largest number
int large = (a>b)?((a>c)?a:c):(b>c?b:c);
Console.WriteLine("Largest number is {0}", large);
//hit ENTER to exit the program
Console.ReadLine();
}
}
}

Output

输出量

First run:
Enter first number : 30
Enter second number: 20
Enter third number : 10
Largest number is 30
Second run:
Enter first number : 10
Enter second number: 30
Enter third number : 20
Largest number is 30
Third run:
Enter first number : 10
Enter second number: 20
Enter third number : 30
Largest number is 30
