Wap ASP.NET MobileCapabilities
概念
我们通过以下代码可以获取手机的能力,从而针对不同能力的手机做出显示彩色还是黑白色的图片，显示的字体是否可以为彩色等等。
还可以进一步通过System.Web.Mobile.MobileCapabilities 的成员函数
System.Boolean HasCapability ( System.String delegateName , System.String optionalParameter )来查询手机是否支持某一特性，代码如下：
bool bHasWBMP =
((MobileCapabilities)Request.Browser).HasCapability("PreferredImageMime", "image/vnd.wap.wbmp");
log.Info("Has WBMP?" + bHasWBMP.ToString());
还可以进一步通过System.Web.Mobile.MobileCapabilities 的成员函数
System.Boolean HasCapability ( System.String delegateName , System.String optionalParameter )来查询手机是否支持某一特性，代码如下：
bool bHasWBMP =
((MobileCapabilities)Request.Browser).HasCapability("PreferredImageMime", "image/vnd.wap.wbmp");
log.Info("Has WBMP?" + bHasWBMP.ToString());
MobileCapabilities Codes
在asp.net页面中安排如下代码即可通过log4net打印出手机的MobileCapabilities：
代码：
private void Page_Load(object sender, System.EventArgs e)
{
if(!IsPostBack)
{
log.Info("-============ 输出MobileCapabilities Begin ==============-");
Type myType =(typeof(System.Web.Mobile.MobileCapabilities));
System.Reflection.PropertyInfo[] myPropertyInfo =
myType.GetProperties(System.Reflection.BindingFlags.Public|System.Reflection.BindingFlags.Instance);
DisplayPropertyInfo(myType, myPropertyInfo);
log.Info("-============ 输出MobileCapabilities End ==============-");
}
。。。}
void DisplayPropertyInfo(Type t,System.Reflection.PropertyInfo[] myPropertyInfo)
{
// Display information for all properties.
System.Web.Mobile.MobileCapabilities m=( System.Web.Mobile.MobileCapabilities)Request.Browser;
for(int i=0;i<myPropertyInfo.Length;i++)
{
Object result=new Object();
System.Reflection.PropertyInfo myPropInfo = (System.Reflection.PropertyInfo)myPropertyInfo[i];
try
{
result = t.InvokeMember (myPropInfo.Name, System.Reflection.BindingFlags.GetProperty|System.Reflection.BindingFlags.GetField, null, m, new object [] {});
}
catch (System.MissingMethodException e)
{
result =e.Message;
}
log.Info ("[" + myPropInfo.Name+ " ]:<" + result+">");
}
}
下面日志对应的手机型号是
Nokia7610/2.0 (4.0424.4ch) SymbianOS/7.0s Series60/2.1 Profile/MIDP-2.0 Configuration/CLDC-1.0
