• .NET Development XmlSerializer or custom serialization?

  Hi! I'm currently not sure whether I should use XmlSerializer to save the properties of a class to an xml file or if should just write the file manually with XmlTextWriter. The problem hereby lies in the speed of deserialization. My program will load an undefined number of such files and create instances of the corresponding class at startup. Thus the deserialization operation should take as few time as possible, even if that means writing more code. If I have a class named Employee with the properties Name, Address, Age, and Salary I'd deserialize it with an XmlReader as follows: while (reader.Read()) {     if (reader. ...Show All

• Visual Studio Team System How can I run a perfomance test capturing the time taken to an open a document from the application

  Our web application enables the opening of a PDF file in an inline frame. Is it possible to measure the performance of when the document open request is made and when it is completed. Running a number of tests always returns the same results which I assume is just the start of the request as the time does not vary in anyway even though it can take a long time for the PDF to open. Response time will be the amount of time it took to download the PDF file. If you're talking about measuring the length of time Acrobat process the PDF, that isn't possible since web tests work at the HTTP level and don't actually open any files in applications ...Show All

• Visual C# Can this be made more efficient?

  Does anyone know of a better way of doing this   I have been tasked to convert a VB 6.0 app over to C# and encountered this routine (there are more like this).  Luckily the original coder believed in documenting but, I'm having a devil of a time trying to convert this to C# code! I've thought of possibly using a regular expression but I'm not at all familiar with them and so far have gotten hopelessly lost.  Can someone please help   My meager attempt at this is below the VB code.  As you can see, I'm very new with C# and there is an obvious error "Operator '||' cannot be applied to operands of type 'bool' and 'st ...Show All
