问题 I've just stumbled across this folder structure on my machine which contains lots of .NET assemblies similar to what you might find in the system GAC. This puzzled my as I've never seen this folder structure before and it makes me wonder, is there such a thing as a local user assembly cache? The folder structure is: C:\Documents and Settings\ [username] \Local Settings\Application Data\assembly\ and contains folders and files that look like: \dl3\8M830QM6.ON7\NJ9Q0EA9.TZO\623c8efc\00461250

问题 Lets say you have this text "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. Fusce posuere, magna sed pulvinar ultricies, purus lectus malesuada libero, sit amet commodo magna eros quis urna." put in a textblock with TextWrapping="Wrap", the textblock only supports 2 lines, so how do I add the usual "..." at the end of the text so as to say there is more to read 回答1: This is not trivial to answer for use in SilverLight because you cannot use native

问题 I have few directories in my IIS server (physical location inetpub\wwwroot\SampleApp) The directories contain .jpeg images. I am iterating these images in C# from Silverlight.

问题 I just discovered a very strange behaviour. I have a class with a string property. In the setter of this property I compare the old value with the new value first and only change property if the values differ: set { if ((object.ReferenceEquals(this.Identifier, value) != true)) { this.Identifier = value; this.RaisePropertyChanged("Identifier"); } } But this ReferenceEquals almost always returns false! Even if I call object.ReferenceEquals("test", "test") in Quick Watch I get false. How is this

问题 Is seems like all the commonly-used classes for XMLValidation, for example XmlValidatingReader, are absent (or present "for interface compatibility only") in Silverlight.

问题 I've managed to discover Gilles Khouzam's playback implementation for WAV files in Silverlight 3 and while that would be the majority of the battle, I'm stuck on a final detail: how do I pull a wav file from the web some place and then feed it into his WaveMediaStreamSource for playback? Here's the closest I've come: public MainControl() { // Required to initialize variables InitializeComponent(); PlayButton.Click += PlayButtonClicked; } private void PlayButtonClicked(object sender,

问题 In my Silverlight app I have UserControl and I want to reference a StaticResource in a ResourceDictionary that is in a separate XAML file.
