我有一個表單上傳文件，但無法將它與其他元素同時保存在同一模型或兩個單獨的模型中。我明白我的第一個問題是我不能嵌套表格，例如如何與其他數據同時上傳文件
@using (Html.BeginForm("Create", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<form class="form-horizontal">
<input />
<input />
@using (Html.BeginForm("Create", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<form class="form-horizontal">
<input image upload/>
<input />
</form>
}
</form>
}
所以我現在有兩個獨立的形式可以很好地工作，但我想幾件事情：1。 當用戶選擇要上傳的圖片任何當前輸入的值不會被刪除2.更新與模型所有輸入的數據（所有表單元素）以及圖像到選定的模型。 3.有沒有辦法以一種形式做到這一點？ （在一個單一的！）。
我將如何實現這一目標？我目前的工作情況如下。
