按代码更改ASP.NET成员资格提供程序

UPDATE

您的CompositeProvider可能看起来像这样,并且可以像在任何其他提供程序中一样在web.config中注册.

public class CompositeProvider : MembershipProvider
{
    private MembershipProvider SqlProvider
    {
        get { return Membership.Providers["Sql Provider"]; }
    }

    private MembershipProvider AdProvider
    {
        get { return Membership.Providers["Ad Provider"]; }
    }

    // This property implements the logic that knows how
    // to switch between the two providers.
    private MembershipProvider Provider
    {
        get
        {
            var context = HttpContext.Current;

            if (context != null)
            {
                var session = context.Session;

                if (session != null &&
                    session["use_ad_provider"] == "true")
                {
                    return AdProvider;
                }
            }

            return SqlProvider;
        }
    }

    public override bool ChangePassword(string username,string oldPassword,string newPassword)
    {
        return Provider.ChangePassword(username,oldPassword,newPassword);
    }

    public override bool DeleteUser(string username,bool deleteAllRelatedData)
    {
        return Provider.DeleteUser(username,deleteAllRelatedData);
    }

    public override bool EnablePasswordReset
    {
        get { return Provider.EnablePasswordReset; }
    }

    public override bool EnablePasswordRetrieval
    {
        get { return Provider.EnablePasswordRetrieval; }
    }

    // TODO: Implementation of all other members.
