使用.NET 6 Core作为控制台应用程序，我无法使调试日志记录正常工作（没有显示任何内容）。并且，我已添加Microsoft.Extensions.Logging.Console到该项目中。

您将在下面看到我尝试获取记录器引用的两种方法。

请注意，这logger.LogInformation确实有效，但logger.LogDebug没有。

问题：我如何开始LogDebug工作？

程序.cs

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

var serviceProvider = new ServiceCollection()
                            .AddLogging(builder => {
                                builder.ClearProviders();
                                builder.AddConsole();
                                builder.AddDebug();
                            })
                            .BuildServiceProvider();

// I've tried this
var logger = serviceProvider.GetService<ILogger<Program>>();

// And this
var logger = serviceProvider.GetService<ILoggerFactory>().CreateLogger<Program>>();

logger.LogDebug("hello world");       // <-- This DOESN'T work
logger.LogInformation("something");   // <-- This DOES work

所以我有一个Angular视图,它有以下标记:

<select id="ddlHandheldIds"
        name="ddlHandheldIds"
        class="form-control"
        ng-model="vm.handheldPayment.handHeldId"
        ng-options="id as id for id in vm.handheldKeys track by id"
        required
        title="select hand held id">
        <option value="">select hand held id</option>
</select>

在vm.handheldKeys当页面被加载是具有两个值的数组[0,24].

页面加载时,呈现的HTML如下(标签为可读性):

<select id="ddlHandheldIds" name="ddlHandheldIds" 
        class="form-control ng-dirty ng-touched ng-valid-parse ng-valid ng-valid-required" 
        ng-model="vm.handheldPayment.handHeldId" 
        ng-options="id as id for id in vm.handheldKeys track by id"    
        required="" 
        title="select hand held id">
    <option value="" class="">select hand held id</option>
    <option value="0" label="0">0</option>
    <option value="24" label="24">24</option>
</select>

当然,这是你所期望的.

现在,通过一些业务逻辑,用户与网页互动之后,有一个功能拼接的vm.handheldKeys阵列.所以,让我们说代码如下所示:

vm.handheldKeys.splice(0,1);  // Remove …
