无法在C#控制台应用程序中运行“Hello World”程序

c#
6

我正在学习C#，并运行控制台应用程序的Hello World程序。当我使用F5运行时，控制台弹出并立即消失。

    using System;

namespace CSharpConsoleApps
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("hello c sharp world ");
        }
    }
}

以下是输出中显示的信息。

你的程序已经成功执行，但控制台会立即关闭。

为了避免这种情况，使用Ctrl+F5，而不是只使用 F5。

这正如你告诉它的那样工作！

基本上，该代码只是说“显示这行文本”。因此，一旦完成，没有其他事情要做，它就停止运行。

尝试添加

Console.ReadKey();

请再次运行它。

计算机做的事情恰好是它们被编程要做的。因此，原始代码没有指示计算机在终止之前等待用户输入。因此，计算机按照所呈现的指令执行，并正常终止程序。
你可以尝试：
namespace CSharpConsoleApps
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("hello c sharp world ");
            Console.ReadLine();
        }
    }
}

然后再次运行它。计算机将等待您按 ENTER 键，然后关闭控制台窗口。

好的，那么我需要提供多少更详细的信息来回答这个问题呢？在我的上面的评论已经回答了为什么控制台窗口会消失的问题，所以再解释一遍就有些多余了。 - spfastjr
奇怪的是我在历史记录中看不到这个评论，所以我不知道它是被争议、拒绝还是标记为有帮助。如果我再看到这个评论，我可能不会将其标记为“不是答案”。 - Rich
