Asp.net MVC P2中無法正確獲取CheckBox值的bug的解決方案

View:

<%=Html.CheckBox("IsBirthday","我是否過生日", item.IsBirthday)%>
Controller:
AUser user = new AUser();
BindingHelperExtensions.UpdateFrom(user, Request.Form);Model:
public class AUser{
　　public bool IsBirthday{get;set;}
}

這樣會發生無法從View中獲取到IsBirthday值的情況

查了許多MS只能以以下方法解決

Controller:

AUser user = new AUser();
BindingHelperExtensions.UpdateFrom(user, Request.Form);
user.IsBirthday= Request.Form["IsBirthday"]=="true";View:
<%=Html.CheckBox("IsBirthday","我是否過生日","true", item.IsBirthday)%>
