好像是你的value没有定义属性和方法，修改如下：
<%@ Page Language="C#" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>test2.aspx</title>
</head>
<body>
<form id="Form1" method="post" runat="server">
<select id="select1" runat="server">
<option value="red">Red</option>
<option value="blue">Blue</option>
<option value="green">Green</option>
</select>
<input id="Submit1" type="submit" value="Submit" runat="server"/>
</form>
<div>
<font> color="<%=select1.Value%>
you select color: <%= select1.Value%>"
</font>
</div>
</body>
</html>
