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></mypropertyinfo.length>

{

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+ " ]:");

}

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

输出的日志如下：
