如何遍历IEnumerable，在Count≠0时将索引1的值显示到文本框？

遍历IEnumerable集合，当集合元素数量不为0时，将索引为1的元素对应值显示到文本框中。

后端逻辑代码 #

public PartialViewResult OnGetDisplayOwnerInfoTable(int value) =>
   Partial(
      "_DisplayDMVPartial", 
      _context
      .ExemptionApplicationDmvinformations
      .Where(x => x.ExemptionApplicationOwnerId == value)
      .ToList()
   );

前端视图代码 #

<tbody>
  <tr>
    <td style="border: 1px solid black; font-weight: bold; text-align: center;">
      @Html.DisplayNameFor(m => m.DmvDob)
    </td>
    <td style="border: 1px solid black; font-weight: bold; text-align: center;">
      @Html.DisplayNameFor(m => m.DriverLicense)
    </td>
  </tr>
@foreach (Models.ExemptionApplicationDmvinformation item in Model) {
  <tr>
    <!-- 
      <td style="border: 1px solid black; text-align: center;">
        item.DmvDob.Value.ToString("MMddyyyy")
      </td>
    -->
    <td style="border: 1px solid black; text-align: center;">
      @item.DmvDob
    </td>
    <td style="border: 1px solid black; text-align: center;">
      @item.DriverLicense
    </td>
  </tr>
}
</tbody>

左侧文本框关联代码 #

后端接口代码 #

public JsonResult OnGetDisplayOwnerInfo(int value) {
   ExemptionApplicationDmvinformation data =
      _context
      .ExemptionApplicationDmvinformations
      .Where(x => x.ExemptionApplicationOwnerId == value)
      .FirstOrDefault();

   return new JsonResult(new {
      DateOfBirth = data.DmvDob.Value.ToString("MMddyyyy"),
      DriversLicenseNumber = data.DriverLicense
   });
}

模型定义代码 #

[Display(Name = "出生日期")] public DateTime? DmvDob { get; set; }
[Display(Name = "驾照编号")] public string? DriverLicense { get; set; }
