相关示例代码：
UserProfile.cs
public class UserProfile: System.Web.Profile.ProfileBase
{
public static UserProfile GetUserProfile(string username)
{
return Create(username) as UserProfile;
}
public static UserProfile GetUserProfile()
{
return GetUserProfile(Membership.GetUser().UserName);
}
public string FacebookUid
{
get
{
return base["FacebookUid"] as string;
}
set
{
base["FacebookUid"] = value;
}
}
}
Web.config文件
<profile enabled="true" inherits="WIF.Web.STS.Classes.UserProfile" defaultProvider="XmlProfileProvider" >
<properties>
<add name="FacebookUid" />
</properties>
<providers>
<add name="XmlProfileProvider" type="Artem.Web.Security.XmlProfileProvider,Artem.Web.Security.Xml" applicationName="/" fileName="Profiles.xml" folder="~/App_Data/"/>
</providers>
</profile>
Register.aspx.cs
profile = WIF.Web.STS.Classes.UserProfile.GetUserProfile(emailAddress);
profile.FacebookUid = "";
当我离开web.config中定义的FacebookUid时;我从web.config得到这个错误：
Configuration Error: This profile property has already been defined.
我已经仔细检查了web.config;该属性条目仅在web.config中出现一次.
我想这是因为我在UserProfile类上设置了具有相同名称的属性.我从web.config中删除了属性/ add [name =’FacebookUid’]条目.一旦我做到了;当我尝试在Register.aspx.cs中设置FacebookUid的值时出现此错误：
The settings property 'FacebookUid' was not found Line 76: profile["FacebookUid"] = "";
我再试一次,这次直接使用ProfileBase类：
修订了Register.aspx.cs
var profile = System.Web.Profile.ProfileBase.Create(emailAddress,true);
profile["FacebookUid"] = "";
修改了web.config：
<profile enabled="true" defaultProvider="XmlProfileProvider" >
<properties>
<add name="FacebookUid" />
</properties>
<providers>
<add name="XmlProfileProvider" type="Artem.Web.Security.XmlProfileProvider,Artem.Web.Security.Xml" applicationName="/" fileName="Profiles.xml" folder="~/App_Data/"/>
</providers>
</profile>
我尝试使用properties / add [name =’FacebookUid’]而没有;在相同的情况下得到与上述相同的错误.
我很难过,谷歌/ Binging让我无处可去.这里有没有人知道可能会发生什么和/或如何解决这个问题？非常感谢任何建设性的意见.
谢谢,
坦率
解决方法
Notes to Inheritors
You can create a custom profile implementation that inherits from the ProfileBase abstract class and defines properties for the user profile that are not specified in the profile configuration element.
