英文:
Blazor render dynamic Markup with Components inside
问题
我正在尝试在其中使用Blazor组件呈现一些动态HTML。<br />
例如：
<div>
文本
<Component 属性1="A1" />
</div>
现在，这个HTML片段来自数据库而不是代码，所以我正在寻找一种方法来强制Blazor重新渲染内容并将组件解析为其HTML表达式。
我已经尝试过使用RenderFragment，但那不起作用。
我还了解了使用RenderTreeBuilder，但那是非常低级的，我需要将其细化到一个程度，以至于使用RegularExpression并将组件替换为传入HTML中的预定义占位符加载的HTML会更容易。
有没有人知道更简单的方法？或者一种强制Blazor重新评估传入的HTML/Razor/Blazor字符串的方法？
英文:
I am trying to render some dynamic HTML with Blazor Components in them.<br />
E.g.:
<div>
Text
<Component Attribute1="A1" />
</div>
Now, this HTML Snippet comes from a database and not from Code, so I am looking for some way to force Blazor to (re?-) render the content and resolve the Component into its HTML-Expression.
I already tried something with RenderFragment, but that did not work.
I also read about using the RenderTreeBuilder, but that is so very low-level, I would need to make it so granular, that it would be easier to use a RegularExpression and replace the component in the incoming HTML with some predefined placeholder-laden-HTML.
Does anyone know an easier way? Or some way to force Blazor to reevaluate the incoming HTML/Razor/Blazor-String?

Straight answer is not possible. You can't store markup code and somehow feed it into the Renderer at runtime.
直接回答是不可能的。你不能在运行时存储标记代码，然后以某种方式将其传递给渲染器。
Why?
为什么？
Markup code, such as:
标记代码，例如：
<div>
Text
<Component Attribute1="A1" />
</div>
is compiled by the Razor compiler into a standard C# class that produces code like this:
Razor 编译器将标记代码编译成一个标准的 C# 类，生成类似以下代码：
protected override void BuildRenderTree(RenderTreeBuilder builder)
{
//...
builder.OpenElement(0, "div");
builder.AddMarkupContent(1, "Text");
builder.OpenComponent<Counter>(2);
builder.AddAttribute(3, "Attribute1", "A1");
builder.CloseComponent();
builder.CloseElement();
//...
}
It's part of the compilation process, not a runtime option.
这是编译过程的一部分，而不是运行时选项。
