我做错了什么？当您使用model.Item1.projectName和model.Item1.projectType时，您的模型看起来像一个复杂的对象，但在action方法中，您试图直接获取值，这是错误的。[更新的代码] 发布新代码后，此模型的快速更正将允许它从您的视图中正确绑定：
namespace reqcoll.ViewModels
{
public class myViewModel
{
public Project project;
public Requirement requirement;
}
}
@helper RenderMyProject(Project project) {
...
@Html.TextBoxFor(x=> project.projectType)
...
}
@RenderMyProject(model.Item1)
如果我只是改变了我的控件和视图来使用一个包含所有需要的模型的类？使用同一个助手？我现在有一个模型类。我使用了助手来简化代码。如果我运行该网站，并且在调用助手的行上设置了断点，我可以看到模型被传递给了助手。但在提交时，输入的信息不会发布。现在是单向交通，我需要双向交通。在你的控制器上设置一个断点。您应该能够检查对象[Request.Form]。键值应表示对象的属性。由于您的创建操作需要一个项目，因此响应键应该包含属性名称（如“projectType”）或参数+属性名称（如“Project.propertyName”），我看到3个键，一个不是我的，另外两个来自我的项目模型。但是没有值。在Request.Form对象中，我们应该看到三个键“_RequestVerificationToken”是您的反ForgeryToken•“Item1.projectName”•“Item1.projectType”您不能在绑定中使用复杂对象。所以，若要在绑定中访问，必须使用具有直接属性的视图模型，而不是复杂的视图模型。
