C＃服务器标签不能包含＆lt;％...％＆gt;结构体

Question

我有这段代码：

<div class="detailBox">
                    <div class="actionBox">
                        <ul class="commentList">
                        <%
                            foreach (System.Data.DataRow drow in members.Rows)
                            {
                        %>
                                <li>
                                    <div class="commentText">
                                        <span><%= drow["nume_user"] %></span>&nbsp;&nbsp;&nbsp;
                                        <asp:Button ID="deleteButton" CssClass="btn btn-danger btn-xs" runat="server" OnClick="deleteMember" Text="Elimina" CommandArgument="<%= drow["id"] %>" />
                                    </div>
                                </li>
                        <%
                            }
                        %>
                        </ul>
                     </div>
                 </div>

我不知道为什么当我想Server tags cannot contain <% ... %> constructs.给CommandArgument drow["id"]时，我会收到此错误 protected void deleteMember(object sender, EventArgs e) { String connString = System.Configuration.ConfigurationManager.ConnectionStrings["GroupsConnString"].ToString(); var argument = ((Button)sender).CommandArgument; Response.Write(argument); if (argument != null) { MySqlConnection conn = new MySqlConnection(connString); conn.Open(); MySqlCommand comm = conn.CreateCommand(); comm.CommandText = "DELETE FROM app_groups.users_groups_leg WHERE id = " + argument; int result = comm.ExecuteNonQuery(); //here you will get the no.of rows effected conn.Close(); } } ，当我点击时如何将此变量传递给后面的代码在按钮上？

EDIT 当我点击按钮时，正在执行的代码：

String trpname="<?xml version='1.0' encoding='UTF-8'?><root available-locales='bg_BG,cs_CZ,de_DE,el_GR,en_GB,es_ES,es_MX,fr_FR,hr_HR,hu_HU,in_ID,it_IT,ja_JP,ko_KR,pl_PL,pt_BR,pt_PT,ro_RO,ru_RU,sk_SK,tr_TR,zh_CN,zh_TW' default-locale='en_US'>"

        String translatedProgramName = HtmlUtil.unescape(trpname);
        String programName = LocalizationUtil.getLocalization(translatedProgramName, "en_US");

我认为您应该使用<%# %>在c＃和html之间切换。所以你的代码应该是

<div class="detailBox">
                <div class="actionBox">
                    <ul class="commentList">
                    <%#
                        foreach (System.Data.DataRow drow in members.Rows)
                        {
                    %>
                            <li>
                                <div class="commentText">
                                    <span><%= drow["nume_user"] %></span>&nbsp;&nbsp;&nbsp;
                                    <asp:Button ID="deleteButton" CssClass="btn btn-danger btn-xs" runat="server" OnClick="deleteMember" Text="Elimina" CommandArgument="<%= drow["id"] %>" />
                                </div>
                            </li>
                    <%#
                        }
                    %>
                    </ul>
                 </div>
             </div>
