选择用ASP.NET开发,ASP.NET开发WAP站点,实在简单,就是一个移动控件的运用,根本不用懂WML语法.唯一不同的,就是一个ASPX文件可以支持多个FORM,不同FORM之间可以切换,
最后ASP.NET根据访问的设备,输出不同的内容,
如果用IE访问就输出HTML,手机访问,输出WML,
不过在开发过程中也遇到了很多问题,一些问题总结如下:
1.模拟器:

<table width="222"  border="0" cellpadding="0" cellspacing="0" id="bkimg" style="display:block"><tr><td height="71" colspan="3" align="left" valign="bottom">
<img src="http://www.roboo.com/pages/images/layout/phone_mb3_up.gif" width="222" height="82"  /></td></tr><tr><td width="28" height="205" align="left" valign="bottom">
<img src="http://www.roboo.com/pages/images/layout/phone_mb3_left.gif" width="28" height="240"  /></td><td width="167" valign="top" >
<iframe name="wbb" id="wbb"    marginheight="0" marginwidth="0" width="165px" height="240px" frameborder="0" src="http://www.roboo.com/pages/simulator/crawldatah.jsp?url=wap.56hui.com"></iframe> 
</td><td width="27" align="right" valign="top">
<img src="http://www.roboo.com/pages/images/layout/phone_mb3_right.gif" width="27" height="240"  /></td></tr><tr><td  colspan="3" align="left" valign="bottom">
<img src="http://www.roboo.com/pages/images/layout/phone_mb3_down.gif" width="222"  />
</td></tr></table>

将"http://www.roboo.com/pages/simulator/crawldatah.jsp?url=m.ta0bao.com"的"m.ta0bao.com"换成自己的wap地址

强制输出WML:
在web.config
添加下面内容<system.web>下

 

<browserCaps>
            <result type="System.Web.Mobile.MobileCapabilities, System.Web.Mobile, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
            <use var="HTTP_USER_AGENT"/>
                     preferredRenderingType = "wml11"
                     preferredRenderingMime = "text/vnd.wap.wml"
                     preferredImageMime = "image/vnd.wap.wbmp"
</browserCaps>

如果定义相关其它属性可以完整的移动设置属性:

    <browserCaps>

具体属性的意思可以考试MSDN:设备功能列表
ms-help://MS.MSDNQTR.2003FEB.2052/mwsdk/html/mwlrfDeviceCapabilitiesTable.htm

但这样将给您在需要IE调试时带来很大的不便
下面代码将能解决IE和模拟器同时高度的问题（同样将下面代码加入system.web节点中）

 

<browserCaps>
<result type="System.Web.Mobile.MobileCapabilities, System.Web.Mobile, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
<use var="HTTP_USER_AGENT"/>
<filter>
<case match="Unknown" with="%{browser}">
preferredRenderingType = "wml11"
preferredRenderingMime = "text/vnd.wap.wml"
preferredImageMime = "image/vnd.wap.wbmp"
type=Unknown
</case>
</filter> 
</browserCaps>

 

2.链接:
在同一个aspx文件,使用Link控件的,#FORM来切换不同Form时在 OPenWave 5.0测试会出现错误!
建议在程序通过ActiveForm来做
3.乱码:
     如果在开发过程出现乱码,通过修改Web.Config
     <globalization
            requestEncoding="gb2312"
            responseEncoding="gb2312"
    />
4.取消移动设备缓存:

 

   Page.Response.Expires = -1;
    Response.CacheControl = "Public";

5.重定向
重定向通过
RedirectToMobilePage函数
不过使用过程中可能会出现一些问题
建议用Link控件来代替
