            **<div class="editor-label">

                <%: Html.TextboxFor(m => m.FirstName)%>
                <%: Html.ValidationMessageFor(m => m.FirstName)%>
            </div>**

            <div class="editor-label">
                <%: Html.LabelFor(m => m.ConfirmPassword) %>
            </div>
            <div class="editor-field">
                <%: Html.PasswordFor(m => m.ConfirmPassword) %>

            <p>
                <input type="submit" value="Register" />
            </p>
        </fieldset>
    </div>
<% } %>

在此代码中，我添加了FirstName名称中的新字段，但收到错误：

'MvcApplication1.Models.RegisterModel'不包含'FirstName'的定义，并且没有扩展方法'FirstName'接受类型为'MvcApplication1.Models.RegisterModel'的第一个参数'（您是否缺少using指令或汇编参考？）

Answer 1

向视图中添加新属性是不够的。

将public string FirstName{ get; set; }添加到您的RegisterModel课程。

应该如下所示。

public class RegisterModel
{
    // other properties

    [Display(Name = "First name")]
    public string FirstName { get; set; }
}

在mvc应用程序中添加其他字段时显示错误
