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＃(或其他編程語言)還允許在另一個條件/三元運(yùn)算符中使用條件/三元運(yùn)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為true，則將檢查logical_test2 ，如果為true，則將執(zhí)行“ true_block” ，否則將執(zhí)行“ false_block” ，如果logical_test1為false，則將執(zhí)行“ false_block_outer” 。

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

注意：根據(jù)條件，可以在任何塊中使用內(nèi)部條件運(yùn)算符。

嵌套條件/三元運(yùn)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.

在這里，我們要求輸入三個數(shù)字并找到最大的數(shù)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 numberint large = (a>b)?((a>c)?a:c):(b>c?b:c);Console.WriteLine("Largest number is {0}", large);//hit ENTER to exit the programConsole.ReadLine();}} }

Output

輸出量

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