<p>在 <code>.NET6/C#10</code> 之后，微软新增了 <code>GlobalUsings</code> 机制，可以在项目的根目录下创建一个 <code>GlobalUsings.cs</code> 文件，把常用的 <code>using</code> 放置其中。</p>
|
|
|
<p>这样 <code>GlobalUsings.cs</code> 所在的项目 <code>.cs</code> 文件就无需重复 <code>using</code> 了，大大的提高开发效率，也让代码变的更加简洁。</p>

|
|
|
<p><strong>启用 <code>GlobalUsings</code> 机制需要以下两个步骤：</strong></p>
|
|
|
<ol>
|
|
|
<li>在你需要全局 <code>using</code> 的项目层根目录创建 <code>GlobalUsings.cs</code> 文件，如果多个项目层需要，则每个层都应该有一个 <code>GlobalUsings.cs</code></li>
|
|
|
<li>编辑项目的 <code>.csproj</code> 文件，添加 <code><ImplicitUsings>enable</ImplicitUsings></code>，注意是在 <code><PropertyGroup></code> 中添加，通常和 <code><TargetFramework></code> 同父同级</li>
|
|
|
</ol>

|
|
|
<p>配置之后，现在就可以把常用的 <code>using</code> 放到 <code>GlobalUsings.cs</code> 中了，写法如下：</p>

<p>在 <code>ASP.NET</code> 的时代，我们通常通过 <code>HttpContext</code> 全局静态类获取请求上下文，但在 <code>ASP.NET Core</code> 中，<code>HttpContext</code> 是一个非静态的抽象类，无法手动创建，也无法通过静态获取。</p>

|
<p>虽然在 <code>ASP.NET Core</code> 中无法直接获取 <code>HttpContext</code> 对象。但是微软也提供了注入 <code>IHttpContextAccessor</code> 方式获取。</p>
