filestream

问题 When trying to pass a small FileStream to my WCF service I get "Timeouts are not supported on this stream" error. Can anyone see what I'm doing wrong? Interface: [OperationContract] List<SystemClass> ReadExcelFile(System.IO.FileStream stream); Web.Config <bindings> <basicHttpBinding> <binding name="streaming" maxReceivedMessageSize="2147483647" transferMode="Streamed"> </binding> </basicHttpBinding> </bindings> <services> <service name="MISDashboard.wcfService" behaviorConfiguration="">

问题 This might seem like a noddy question, but I was looking at this because I heard someone claiming that you must call Close() on a FileStream, even if it is in a using block (and they have code where Close() is being called right at the end of the block). I know that Close() is meant to call Dispose(), but I thought I'd look deeper since this is .Net 1.1 code, and the bulk of my experience has been with 2.0 on. One thing that struck me was that the MSDN documentation for FileStream has Dispose

问题 I have a c# component that will recieve a file of the following types .doc, .pdf, .xls, .rtf These will be sent by the calling siebel legacy app as a filestream. So... [LegacyApp] >> {Binary file stream} >> [Component] The legacy app is a black box that cant be modified to tell the component what file type (doc,pdf,xls) it is sending. The component needs to read this binary stream and create a file on the filesystem with the right extension. Any ideas? Thanks for your time. 回答1: On Linux/Unix

问题 Why am I receiving the above error message when I use using (fileStream = new FileStream(path, FileMode.Append, FileAccess.Write)) but the programme executes perfectly when I replace it with fileStream = File.Create(path); ? I want to append the console output to an external file. Here's my code: //copy console output to file in bin\Debug folder class ConsoleCopy : IDisposable { FileStream fileStream; StreamWriter fileWriter; TextWriter doubleWriter; TextWriter oldOut; class DoubleWriter :

问题 Is the following pattern of multi-threaded calls acceptable to a .Net FileStream? Several threads calling a method like this: ulong offset = whatever; // different for each thread byte[] buffer = new byte[8192]; object state = someState; // unique for each call, hence also for each thread lock(theFile) { theFile.Seek(whatever, SeekOrigin.Begin); IAsyncResult result = theFile.BeginRead(buffer, 0, 8192, AcceptResults, state); } if(result.CompletedSynchronously) { // is it required for us to
