Question

我正在尝试创建一个管理员可以编辑用户的页面。我的代码是：

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="ManageUsers.aspx.cs" Inherits="SiteStiri.Administration.ManageUsers" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" Runat="Server">

    <asp:Repeater ID="FilteringUI" runat="server">
         <ItemTemplate> 
             <asp:LinkButton runat="server" ID="lnkFilter" Text='<%# Container.DataItem %>' CommandName='<%# Container.DataItem %>'>

             </asp:LinkButton> 

         </ItemTemplate> 
        <SeparatorTemplate>|</SeparatorTemplate>

    </asp:Repeater>

    <asp:GridView ID="UserAccounts" runat="server" AutoGenerateColumns="False">
         <Columns> <asp:BoundField DataField="UserName" HeaderText="UserName"/> 
             <asp:BoundField DataField="Email" HeaderText="Email" /> 
             <asp:CheckBoxField DataField="IsApproved" HeaderText="Approved?"/> 
             <asp:CheckBoxField DataField="IsLockedOut" HeaderText="Locked Out?" /> 
             <asp:CheckBoxField DataField="IsOnline" HeaderText="Online?"/> 
             <asp:BoundField DataField="Comment" HeaderText="Comment"/> 

         </Columns> 

    </asp:GridView>


</asp:Content>

主页面（我在制作东西之前首先按照教程进行操作）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;

namespace SiteStiri.Administration
{
    public partial class ManageUsers : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                BindUserAccounts();
                BindFilteringUI();
            }
        }
        private void BindUserAccounts()
        {
            UserAccounts.DataSource = Membership.GetAllUsers();
            UserAccounts.DataBind();
        }

        private void BindFilteringUI() { 
            string[] filterOptions = { "All", "A", "B", "C", "D", "E", "F", "G", "H",
                                         "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" };
            FilteringUI.DataSource = filterOptions; 
            FilteringUI.DataBind();
        }
    }
}

页面背后的代码。

当我运行它时，我收到以下错误

An exception of type 'System.Configuration.Provider.ProviderException' occurred in System.Web.dll but was not handled in user code

Additional information: Default Membership Provider must be specified.

这里必须做些什么，我如何指定默认成员资格提供商以及它是什么？

Extended error eport:

  InnerException:

这是Web.config：

   <?xml version="1.0"?>
 <configuration> 
   <system.web> 
     <authorization> 
       <allow roles="canEdit" />
        <deny users="*"/>
     </authorization> 
   </system.web> 
</configuration>

根据我的阅读，我必须在网络配置中添加一些东西吗？

请查看this post有关如何正确配置会员提供商的信息。

简而言之 - 您需要在Membership部分中设置defaultProvider：

<configuration>
    <system.web>
        <membership defaultProvider="SqlProvider">
            <providers>
                <clear />
                <add name="SqlProvider" 
                    many more settings here...
                />
            </providers>
        </membership>
    </system.web>
</configuration>
