Debug.WriteLine(“Hello World!”) - 没有出现在 output 中

Question

Problem

I am developing a UWP ( Universal Windows Platform ) application and as a test I included the

Debug.WriteLine("Hello World;"); method, but in the output the text entered in the method was not displayed.

Question

Was the method incorrectly integrated into the UWP application by me?

Source Code

using System;
using System.Diagnostics;
using Windows.System;
using Windows.UI.ViewManagement;
using Windows.UI.Xaml.Controls;

// The Blank Page item template is documented at https://go.microsoft.com/fwlink/?LinkId=402352&clcid=0x409

namespace UwpApplication1
{
    /// <summary>
    ///     An empty page that can be used on its own or navigated to within a Frame.
    /// </summary>
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            
            Debug.WriteLine("Hello World! - Debug.Writeline() Test");

        }
    }
}

If you want ' Hello, World ' to be shown in the Visual Studio output and not the UWP Application, You just write Console.WriteLine() instead of Debug.WriteLine() .

If you want to it to be shown in the UWP Application, you create a text block (without code). Writing 'Hello, World!" in the debug will just show a comment in the output that cannot be seen by the user in the actual app.

If you want a console output just type in Console.WriteLine() .
