自从公司网站http://bbs.cnfdc.com.cn 用上了cs2.0，就有同事给我提出，能不能添加一个帖子底部的快速回复，这样可以很方便的回复帖子，当时刚接触cs，没有弄，现在，觉得对于cs比较熟悉了，于是就下手做了一个，没想到，成功了，现在就和大家分享一下吧。

我采用的是cs的标准方法，即用户控件的方式，建立一个皮肤文件，然后给这个皮肤文件对应写一个类。皮肤文件可以说是skin-Login.ascx和CreateQuickReplay.ascx的混合体，类文件也一样，不过由于要求游客可以通过一并输入用户名和密码的方式来发帖，所以先登录用户，这里就去掉了一些验证，放在用户登录后进行。

先把初步的皮肤文件的代码放上来，文件名Skin-ThreadQuickReply.ascx，放在default主题目录下

<%@ Control Language="C#" %>

<%@ Register TagPrefix="CSD" Namespace="CommunityServer.Discussions.Controls" Assembly="CommunityServer.Discussions" %>

<%@ Register TagPrefix="CS" Namespace="CommunityServer.Controls" Assembly="CommunityServer.Controls" %>

<%@ Import Namespace="CommunityServer.Discussions.Controls" %>

<%@ Import Namespace="CommunityServer.Discussions.Components" %>

<%@ Import Namespace="CommunityServer.Components" %>

<%@ Import Namespace="CommunityServer.Controls" %>

<%@ Import Namespace="CommunityServer" %>

<li>

<td align="left">快速回复主题</td>

</td>

</tr>

</table>

</h4>

<CSD:UserPermissions runat="server" id="Userpermissions1" />

</div>

</td>

<tr>

<asp:Panel ID="UserLoginForm" runat="server">

<CS:DefaultButtonTextBox Button = "loginButton" id="username" runat="server" size="30" maxlength="64" />

<CS:DefaultButtonTextBox Button = "loginButton" TextMode="Password" id="password" runat="server" size="11" maxlength="64" />

<asp:CheckBox type="checkbox" Checked="true" runat="server" id="autoLogin" />

<asp:LinkButton id="loginButton" runat="server" CssClass = "CommonTextButton" /><a href="/user/CreateUser.aspx">立即注册</a>

</asp:Panel>

</td>

</tr>

<tr>

</tr>

<tr>

<asp:requiredfieldvalidator id="Requiredfieldvalidator1" runat="server" Cssclass="CommonValidationWarning" ControlToValidate="PostBody" >*</asp:requiredfieldvalidator>

<CS:Editor runat="Server" EnableHtmlModeEditing="false" id="PostBody" Width="660" Height="200" />

</td>

</tr>

<tr>

<asp:button id="SavePost" Runat="server" Text = " 发表 " />

</td>

</tr>

</table>

</td>

</tr>

</ul>

</td>

</tr>

</table>

</div>

</li>

</ul>

</div>

然后就是ThreadQuickReply.cs，放在CommunityServerForums20项目的根目录下即可：
