C# Boolean结构体代码示例

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了C#中System.Boolean结构体的典型用法代码示例。如果您正苦于以下问题:C# Boolean结构体的具体用法?C# Boolean怎么用?C# Boolean使用的例子?那么恭喜您, 这里精选的结构体代码示例或许可以为您提供帮助。



Boolean结构体属于System命名空间,在下文中一共展示了Boolean结构体的11个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的C#代码示例。

示例1: Main

//引入命名空间
using System;

public class Example
{
   public static void Main()
   {
      bool raining = false;
      bool busLate = true;

      Console.WriteLine("It is raining: {0}", raining);
      Console.WriteLine("The bus is late: {0}", busLate);
   }
}
