我在空白注册表单上单击提交时收到此错误。传递到字典中的模型项的类型为“project.Models.CustomerRegistration”，但此字典需要“project.Models.LoginModel”类型的模型项。
答案 0 :(得分：1)
当您尝试绑定到强类型部分视图的模型为null时，会出现该错误。在页面内渲染此局部视图时，如果将空模型传递给@Html.Partial(...)方法，则渲染器默认为发送当前页面的模型。
你的问题是在这个动作中（我假设它对应于你上面的父视图）你这样做：
public ActionResult Registration(int ReferalId)
{
CustomerRegistration cr = new CustomerRegistration();
cr.ReferalId = ReferalId;
return PartialView(cr);
}
但在你看来，你这样做：
@{
project.Models.CustomerRegistration CustReg = ViewBag.CustReg;
project.Models.ForgetPassModel ForgotPassword = ViewBag.ForgotPassword;
project.Models.LoginModel Login = ViewBag.Login;
project.Models.LocalPasswordModel localpassword = ViewBag.localpassword;
}
ViewBag不是一些神奇的空对象生成器。这是一个字典，您可以在一个请求的持续时间内存储与模型无关的数据。除了不首先填充ViewBag之外，您遇到的主要问题是您使用return PartialView(...)呈现所有视图。此呈现方法会忽略您在ViewBag中完全设置的任何内容。因此，为了解决您的问题，我们需要进行一些小的修改，假设您的Login和ForgotPassword partials的模型应该是空的。
@{
// delete the custReg, let the partial inherit the model from the parent
project.Models.ForgetPassModel ForgotPassword = new project.Models.ForgetPassModel();
project.Models.LoginModel Login = new project.Models.LoginModel();
project.Models.LocalPasswordModel localpassword = new project.Models.LocalPasswordModel();
}
@Html.Partial("Registration")
@Html.Partial("_Login", Login)
@Html.Partial("_ForgotPassword", ForgotPassword)
