当我单击按钮提交表单时,viewModel没有绑定。我不确定这是否与model属性是一个数组有关。
控制器
[HttpPost]
public async Task<IActionResult> CommodityAdditionalCodes(CommodityAdditionalCodesViewModel viewModel)
{
//todo code in here which calls webservice
return View(viewModel);
}
ViewModel
public class CommodityAdditionalCodesViewModel
{
public CommodityAdditionalCodeType[] Types { get; set; }
}
查看
@model Asm.Helios.ToolboxMvc.ViewModels.CommodityAdditionalCodesViewModel
@{
ViewData["Title"] = "CommodityAdditionalCodes";
}
<Section>

答案 0 :(得分:3)
不要使用foreach
循环,而要使用经典的for
并为模型建立索引,例如Model.Types[index]
。
另外,您应该考虑使用标签帮助程序,它使Razor代码更容易阅读,因为它与真实HTML更加相似。
@for (var index = 0; index < Model.Types.Count; index++)
{
<input type="text" asp-for="Model.Types[index].Origin" />
<!-- etc... -->
}
