Asp.net mvc 传递到字典中的模型项是类型，但dicitonary需要类型为的模型项
我是ASP.NETMVC的初学者，我有一个相当奇怪的问题，我似乎无法解决如何解决。我通过谷歌找到了同一问题不同版本的多种解决方案，但它们似乎与我的问题无关。如果有人能帮我找出错误，我将不胜感激 编辑：我知道将@model app.Models.Authentication更改为@model app.Models.ContactMessage会修复它，但我不明白为什么，而且显然，建议的修复会给我带来一系列与表单相关的其他错误。 我的错误：传入字典的模型项的类型为“app.Models.Auth”，但此字典需要类型为“app.Models.ContactMessage”的模型项 相关问答： 堆栈跟踪：Asp.net mvc 传递到字典中的模型项是类型，但dicitonary需要类型为的模型项,asp.net-mvc,Asp.net Mvc,我是ASP.NETMVC的初学者，我有一个相当奇怪的问题，我似乎无法解决如何解决。我通过谷歌找到了同一问题不同版本的多种解决方案，但它们似乎与我的问题无关。如果有人能帮我找出错误，我将不胜感激 编辑：我知道将@model app.Models.Authentication更改为@model app.Models.ContactMessage会修复它，但我不明白为什么，而且显然，建议的修复会给我带来一系列与表单相关的其他错误。 我的错误：传入字典的模型项的类型为“app.Models.Auth”，

我认为您需要
返回重定向到操作（“ActionName”、“ControllerName”）返回重定向结果（“Path”）重定向到操作RedirectResult返回RedirectToAction（“ActionName”、“ControllerName”）返回RedirectResult（“Path”）重定向到操作RedirectResult @Html.Partial("_Contact")
@Html.Partial("_Contact", new ContactMessage())
@Html.Partial("_Contact", Model)
@Html.Partial("_Contact")
@Html.Partial("_Contact", new ContactMessage())
@Html.Action("Contact", "Home")
然后，您可以在
HomeControllerContact @Html.Partial("_Contact")
@Html.Partial("_Contact", new ContactMessage())
@Html.Partial("_Contact", Model)
@Html.Partial("_Contact")
@Html.Partial("_Contact", new ContactMessage())
@Html.Action("Contact", "Home")
