使用MVVM
The WPF solution has much the same structure as the Silverlight one; however, all of the ViewModel, View and Resource files are included as links, as per the steps described above.
Resolution Techniques
1.Conditional compilation (#if)
private string ReadFileToString(string filename)
{ #if !SILVERLIGHT using (var stream = this.GetType().Assembly.GetManifestResourceStream(
"SLUGUK.ViewModel." + filename))
{
StreamReader reader = new StreamReader(stream);
string xml = reader.ReadToEnd();
return xml;
} #else string path = "/SilverlightTwitterApp;component/ViewModel/" + filename;
Uri uri = new Uri(path, UriKind.Relative);
StreamResourceInfo sri = Application.GetResourceStream(uri);
StreamReader reader = new StreamReader(sri.Stream);
string xml = reader.ReadToEnd();
return xml; #endif
}
2.Partial classes
3.Design Patterns
使用 适配器模式
对于新的系统，会有多点触控技术。能把任务分解为两个方面的工作，一是同时采集多点信号，二是对每路信号的意义进行判断，也就是所谓的手势识别，从而实现屏幕识别人的五个手指同时做的点击、触控动作。
