您是否考虑过使用局部视图？
控制器：

[Route("no-partial")]
public IActionResult Index()
{
    var model = new CustomModel()
    {
        Name = "Home",
    };

    return View("~/Views/Home/Index.cshtml", model);
}

[Route("with-partial")]
public IActionResult IndexWithPartialView()
{
    var model = new CustomModel()
    {
        Name = "Home",
        PartialViewPath = "~/Views/Shared/_MyPartialView.cshtml"
    };

    return View("~/Views/Home/Index.cshtml", model);
}

浏览次数：

@model CustomModel

@{
    ViewData["Title"] = "Home Page";
}

<div class="text-center">
    <h1>Welcome to homepage</h1>
    @if (Model.PartialViewPath != null)
    {
        @await Html.PartialAsync(Model.PartialViewPath)
    }
</div>

局部视图：

<div>
    <h1>Hello from Partial View</h1>
</div>

结果如下：
https：//localhost：7230/no-partial

<main b-bddmc6yalx="" role="main" class="pb-3">
    <div class="text-center">
        <h1>Welcome to homepage</h1>
    </div>
</main>

https：//localhost：7230/with-partial

<main b-bddmc6yalx="" role="main" class="pb-3">
    <div class="text-center">
        <h1>Welcome to homepage</h1>

        <div>
            <h1>Hello from Partial View</h1>
        </div>
    </div>
</main>

有关部分视图的更多信息，请参阅以下内容：https://learn.microsoft.com/en-us/aspnet/core/mvc/views/partial?view=aspnetcore-7.0
在我看来，这不是最好的做法。我会建议制作多个较小的局部视图，然后只用它们构建视图。我的意思是：

Create.cshtml:
- Partial_Form
- Partial_CreateButtons
- Partial_Form2

Edit.cshtml:
- Partial_Form
- Partial_EditButtons
- Partial_Form2
- Partial_DeleteButtons

Detail.cshtml:
- Partial_Form
- Partial_Form2
- Partial_DetailButtons

您将有3个视图，但是内容将从这些部分视图构建，您将“硬编码”到视图中。因此，每当您需要编辑某些内容时，您将编辑较小的组件/视图，而不是巨大的通用视图。
