我试图在Index.cshtml视图的表单提交上调用Action方法“Createdirect”。
我想在同一视图中列出并创建。代码适用于list ..it显示数据，但在尝试创建时，它不会将表单数据传递给action方法..它传递空值，如附带的屏幕截图所示。

ViewBag.Title = "Index";

答案 0 :(得分：0)
使用foreach循环时，模型绑定不起作用，因为html控件没有使用有意义的ID进行渲染。
将循环更改为for循环：
@for (int i = 0; i < Model.Item2.Length; i++)
{
<tr>
<td>
@Html.DisplayFor(model => model.Item2[i].First_Name)
</td>
<td>
...
您可能还有一个问题（但首先尝试），因为IEnumerable不是绑定点的实例。如果是这种情况，那么唯一的解决方案是将基于元组的模型更改为类实现：
public class MyModel
{
public Customer_MVC Item1 { get; set; }
public IEnumerable<Customer_MVC> Item2 { get; set; } = new List<Customer_MVC>();
}
