问题 There is no StopWatch for Silverlight. What would you use instead of it? I saw some posts about people saying to create an empty animation and call GetCurrentTime() from the Storyboard class, I couldn't get it to work... What would you do? 回答1: This is what I did. Its simple and worked very well for me: long before = DateTime.Now.Ticks; DoTheTaskThatNeedsMeasurement(); long after = DateTime.Now.Ticks; TimeSpan elapsedTime = new TimeSpan(after - before); MessageBox.Show(string.Format("Task

问题 Part of my Silverlight application requires data from three service requests. Up until now I've been chaining the requests so as one completes the other starts... until the end of the chain where I do what I need to do with the data. Now, I know thats not the best method(!). I've been looking at AutoResetEvent (link to MSDN example) to thread and then synchronize the results but cannot seem to get this to work with async service calls. Does anyone have any reason to doubt this method or

问题 When I rename a project within a solution, and then try and build that project, I get the error: "The project file "xyz.csproj" was not found. Where xyz is the old project file name! The annoying thing is that I can search my project & solution for the old project file name, and the search will come up with nothing, and when I click on the error VS does nothing. So there seems to be no way of finding where the old reference is. This is a .web project hosting a silverlight page, if that makes

问题 I have read a range of articles on advantages/disadvantages of Microsoft Silverlight framework in comparisson to Flash. Fact that there were two version of Silverlight in the past 18 months worries me, as well as the fact that over 97% of web browsers already have Flash pre-installed. I'm a .NET developer and I'm very happy with what I can do in the framework. At the moment I feel like I have to put my own preference to a side and decide whether I need to integrage flash with .NET instead of

问题 I need to deploy a Silverlight 2.0 application to an Apache Server, but it's under Linux. Is this possible? I mean, Do I need .Net 3.5 installed in the server and a Web Site that can execute Asp.Net? Thanks for you help... 回答1: If the apache server is just serving up the silverlight application without any ASPX pages then you should be fine. Silverlight is a client side technology so it shouldn't require .NET on the server (unless of course you are hosting the silverlight application on an

问题 In VS2010, Silverlight 4, .NET 4, I've got a WCF service and a Silverlight app, and Silverlight is accessing the class not with Add Service Reference but by sharing the contract. Naturally, this means I have the contract in a Silverlight class library, and the service has a project reference to that library.
