我想在 boostrap identity 2.0 注册表单中添加一个复选框,以确保用户同意网站的条款和条件。出于某种原因,我得到了错误Cannot implicitly convert type 'bool?' to 'bool'
,我不确定为什么。
AccountViewModel.cs
[Required]
[Display(Name = "Agree Terms and Conditions")]
public Nullable<bool> Agree { get; set; }
注册.cshtml
@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @id = "contact-form", role = "form" }))
{
<div class="form-div-5">
<label>
@Html.CheckBoxFor(m => m.Agree, new { @checked = "checked" });
</label>
</div>
}

我认为复选框是真还是假,布尔值也是如此。
