这是我的观点:
@using (Html.BeginForm("Save", "Test", FormMethod.Post))
{
<label for="txtFirstName">First Name</label>
<input id="txtFirstName" type="text" />
<label for="txtLastName">Last Name</label>
<input id="txtLastName" type="text" />
<label for="txtUsername">Username</label>
<input id="txtUsername" type="text" />
<label for="txtEmail">Email</label>
<input id="txtEmail" type="text" />
<input type="submit" value="Save"/>
}
这是我的ActionMethod:
public RedirectToRouteResult Save()
{
var user = new User();
TryUpdateModel(user);
Database.SaveEntity(user);
return RedirectToAction("Index");
}
这是我的模特:@model Game.Model.User
当我调试并转发TryUpdateModel时,用户对象不会更新为我在视图中输入的值。
谁能看到我哪里出错了?

您没有收到后备后的表单数据。
试试这个:
public RedirectToRouteResult Save(string txtFirstName, string txtLastName,
string txtUsername, string txtEmail)
{
var User = new User();
user.FirstName = txtFirstName;
user.LastName = txtLastName;
user.Username = txtUsername;
user.Email = txtEmail;
TryUpdateModel(user);
Database.SaveEntity(user);
return RedirectToAction("Index");
}
要使用强类型视图,请执行以下操作:
@model Game.Model.User
@using (Html.BeginForm("Save", "Test", FormMethod.Post))
{
@Html.LabelFor(m => m.FirstName)
@Html.EditorFor(m => m.FirstName)
@Html.LabelFor(m => m.LastName)
@Html.EditorFor(m => m.LastName)
@Html.LabelFor(m => m.Username)
@Html.EditorFor(m => m.Username)
@Html.LabelFor(m => m.Email)
@Html.EditorFor(m => m.Email)
<input type="submit" value="Save"/>
}
然后更改您的操作方法签名以接收User
:
public RedirectToRouteResult Save(User user)
{
TryUpdateModel(user);
Database.SaveEntity(user);
return RedirectToAction("Index");
}

观看视频:
<input id="txtFirstName" type="text" />
我认为你应该添加name
属性
<input id="txtFirstName" type="text" name="FirstName" />
或简单的方法:
@Html.TextBoxFor(m=>m.FirstName)
