OracleMembershipProvider与登录控件使用的技巧

判断用户是否已经登录，如果没有登录则转向登录页面。参数ReturnUrl是当前请求页面，用户登录后，转向该页面。

  //判断用户是否经过了验证
        if (!User.Identity.IsAuthenticated)
        {
            //用户未经过验证，转向登录页面
            Server.Transfer(FormsAuthentication.LoginUrl + "?ReturnUrl=" + Request.Path);

        }
        else
        { 
            //用户经过了验证，更新当前活动时间
            string strName = User.Identity.Name;
            Membership.GetUser(strName, true);

            
        }

在登录页面进行小小的处理，实现“登录”按钮的点击事件，以便用户登录后转向请求页面。

protected void Login1_LoggedIn(object sender, EventArgs e)
    {
        string strRedirect = Request["ReturnUrl"];
        if(string.IsNullOrEmpty(strRedirect))
        {
            strRedirect = FormsAuthentication.DefaultUrl;
        }
        this.Response.Redirect(strRedirect);
    }

用户申请帐号时，如果需要经过管理员核准后才予以使用，则在创建用户向导的“创建”按钮事件中，更新IsApproved的值

protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
    {
       
            MembershipUser user = Membership.GetUser(CreateUserWizard1.UserName, false);
            user.IsApproved = false;//用户需要验证后才能登录
            Membership.UpdateUser(user);
            }

用户管理：核准、解锁、删除
html页使用Repeater控件

  <asp:Repeater ID="RepeaterItems" runat="server" OnItemDataBound="RepeaterItems_ItemDataBound" OnItemCommand="RepeaterItems_ItemCommand">
            <HeaderTemplate>
                <table cellspacing="1" align="center" cellpadding="3" border="0" style="background-color: #999999;
                    width: 699;">
                    <tr class="style3" align="Center" style="font-weight: bold;">
                        <td class="hstyle">
                            用户名</td>
                        <td class="hstyle">
                            email</td>
                        <td class="hstyle">
                            取回密码时的问题</td>
                        <td class="hstyle">
                            最后活跃时间</td>
                        <td class="hstyle" style="width: 51px;" nowrap>
                            批准</td>
                        <td class="hstyle" style="width: 51px;" nowrap>
                            解锁</td>
                        <td class="hstyle" style="width: 51px;" nowrap>
                            删除</td>
                    </tr>
            </HeaderTemplate>
            <ItemTemplate>
                <tr class="style3" onmouseover="this.style.backgroundColor='#E8F9FD'" onmouseout="this.style.backgroundColor='#ffffff'"
                    style="background-color: White;">
                    <td align="Center">
                        <%# Eval("UserName")%>
                    </td>
                    <td align="Center">

                    <td align="Center">

                    <td align="Center">

                    </td>
                    <td align="center">
                        <asp:LinkButton ID="LinkButton1" runat="server" Font-Underline="true"></asp:LinkButton>

                    </td>
                </tr>
            </ItemTemplate>
            <FooterTemplate>
                </table>
            </FooterTemplate>
        </asp:Repeater>
