說明將 ASP.NET MVC 專案的 Boostrap 升級至 5.x 版本的相對應設計調整。
說明
更新前先進行版本控制，以免有需要回復的情況，接著使用 Nuget 將 Bootstrap 更新至 5.x。
更新 Layout.cshtml

body {
padding-top: 70px;
padding-bottom: 20px;
}
/* Set padding to keep content from hitting the edges */
.body-content {
padding-left: 15px;
padding-right: 15px;
}
/* Override the default bootstrap behavior where horizontal description lists
will truncate terms that are too long to fit in the left column
*/
.dl-horizontal dt {
white-space: normal;
}更新 bundleConfig.cs
public class BundleConfig
{
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate*"));
bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
"~/Scripts/modernizr-*"));
bundles.Add(new Bundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js"));
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));
}
}加入 Scaffolding
原本 ASP.NET MVC 的 Scaffolding 是為 Bootstrap 3 所設計，必須調整為 Bootstrap 5 否則必須逐一修改。
首先加入 CodeTemplates 資料夾，接著從 CodeTemplates 按照下列結構，複製相關檔案後加入到專案。
├─MvcControllerWithContext
│ Controller.cs.t4
│
└─MvcView
Create.cs.t4
Delete.cs.t4
Details.cs.t4
Edit.cs.t4
Empty.cs.t4
Imports.include.t4
List.cs.t4
ModelMetadataFunctions.cs.include.t4
Scaffolding 呈現的風格
