xiyou求解答，CS0165: 使用了未赋值的局部变量“dr”，请问该怎... [复制链接]

行51是错误的，我想将value值改成<%=dr["content"]%>，可是修改后的页面就显示：CS0165: 使用了未赋值的局部变量“dr”，不知道该怎么给dr复制呢

行 49: <div class="feedback_box"><div class="tit">在线提问<a name="ask"></a></div>
行 50: <ul><li style="float: left; width: 100px; height: 2px; text-align: right"><span style="color: #ff0000"></span></li>
[color=Red]行 51: <li style="float: left"><input class="f_tb" id="title" maxlength="50" size="55" name="title" type="hidden" value="<%=dr["content"]%>" /></li>[/color]
行 52: <li style="clear: both; font-size: 1px; line-height: 0px; height: 2px">&nbsp;</li>
行 53: <li style="float:left; width:100px;height:20px;text-align:right"><span style="color: #ff0000">*</span>您的邮箱：</li>
