ASP.NET Tag Helpers失效：Edit/Delete按钮点击无响应求助

问题现象 #

• 此前正常的Edit和Delete按钮，重启项目后点击无响应，但Create按钮可正常工作
• Visual Studio中Create按钮的asp-controller与asp-action属性显示为绿色，Edit/Delete的相关属性无此高亮显示

页面代码 #

@model IEnumerable<Customer>
@{
    ViewData["Title"] = "Index";
}

<h2 class="display-5 mt-3 mb-1 fw-bold">Customer</h2>
<p class="mb-4">To home page</p>

<a asp-controller="Customer" asp-action="Create" class="btn btn-primary mb-2 mt-3">Create</a>

<table class="table table-bordered table-striped">
    <thead class="table-header bg-primary ">
        <tr>
            <th scope="col">
                Company Name
            </th>
            <th scope="col">
                Contact Person
            </th>
            <th scope="col">
                Email
            </th>
            <th scope="col">Phone</th>
            <th ">Active</th>
        </tr>
    </thead>
    @foreach (var obj in Model)
    {
        <tbody>
            <tr>
                <td>
                    @obj.CompanyName
                </td>
                <td>
                    @obj.ContactPerson
                </td>
                <td >
                    @obj.Email
                </td>
                <td >
                    @obj.PhoneNumber 
                </td>
                <td >
                    @obj.Active
                </td>
                <td>
                    <div class="w-75 btn-group" role="group">
                        <a asp-controller="Customer" asp-action="Edit" asp-route-id="@obj.Id"
                           class="btn btn-primary mx-2">Edit</a>
                        <a asp-controller="Customer" asp-action="Delete" asp-route-id="@obj.Id"
                           class="btn btn-danger mx-2">Delete</a>
                        <a href="https://getbootstrap.com/" class="bg-info">
                           is this a tag working</a>
                    </div>
                </td>
            </tr>
        </tbody>
    }
</table>

解决方案 #

• 修复HTML语法错误：代码中<th ">Active</th>存在语法错误，多余的引号破坏了HTML结构与Razor标签助手的解析，修改为： <th scope="col">Active</th>
• 调整表格结构：tbody标签不应嵌套在foreach循环内，一个表格仅需一个tbody，将循环移至tbody内部遍历行：

  <tbody>
      @foreach (var obj in Model)
      {
          <tr>
              <!-- 行内容 -->
          </tr>
      }
  </tbody>
  

• 验证控制器方法：确认CustomerController中存在Edit(int id)和Delete(int id)的GET请求方法，路由配置正常
• 清理重建项目：在Visual Studio中执行清理解决方案→重建解决方案，清除缓存后重新运行项目
