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
