我的控制器中有一些數據（數據合同列表）。我想在我的視圖中顯示該列表的字段/值。我該如何正確地做到這一點？這是我的控制器中獲取列表數據的代碼：public List<ShipmentDataContract> Get(long shipmentServiceId) { Logging.Instance.Info($"Shipment request came in for shipment with ShipmentServiceId = {shipmentServiceId}"); ShipmentQueryResult shipmentQueryResult = GetShipmentByShipmentServiceIdResult(shipmentServiceId); Logging.Instance.Debug($"Shipment queried with ShipmentServiceId = {shipmentServiceId}"); List<ShipmentDataContract> shipmentDataContracts = GetShipmentsFromResult(shipmentQueryResult); Logging.Instance.Info($"Shipment retrieved for shipment with ShipmentServiceId = {shipmentServiceId}."); return shipmentDataContracts; }此方法返回數據合同列表（在本例中只有一個）。我在同一個控制器內以及 Index 方法內創建了一個測試方法：public ActionResult Index() { var shipmentDataTest = Get(94); ViewBag.shipmentTestData = shipmentDataTest; return View(); }當我調試后端時，它返回正確的裝運（ID 為 94）?，F在我想在我的視圖中顯示裝運信息。在我看來，我做了一個變量：<script> var shipmentTestData = '@ViewBag.shipmentTestData';</script>在我的 Vue 應用程序文件中分配了正確的值：var Vue = new Vue({ el: "#vueapp", components: ["error"], data: { shipmentTestData: shipmentTestData }});比起我調用數據時，它不會顯示值，而是顯示通用字符串。<p>{{ shipmentTestData }}</p>它返回這個：System.Collections.Generic.List`1[ShipmentDataContract]有人知道如何解決這個問題嗎？出于某種原因，我分配的變量是格式字符串，這導致了我假設的這個問題，但我該如何解決這個問題？

這是正確的方法。
模型：
public class ShipmentData
{
Task<List<ShipmentDataContract>> Get(long shipmentServiceId)
{
return YourList;
}
控制器：
public ActionResult Index()
{
var shipmentDataTest = ShipmentData.Get(//index);
return View(shipmentDataTest);
}
看法：
@Model YourShipmentModel
//here you can call Model.variable

如果您想將列表用作字符串，您可以發送結果
IList<string> someStrings = Get(94); // i assume than get method returns a list of "strings"
string joined = string.Join(",", someStrings );
ViewBag.shipmentTestData = joined;
現在您要將列表“shipmentDataTest”作為逗號分隔列表發送給前端。讓我知道這是否是您要找的東西。問候。
