• Is the following array really multidimensional?

  - by flockofcode

  Book I’ learning from claims that intArray has two dimensions. But since calling intArray.GetLength(1) will result in an IndexoutOfRange exception, couldn’t we claim that unlike rectangular arrays, intArray isn’t really multidimensional and thus has only one dimension? int[][] intArray=new int[3][]; thank you

• Asyncronous While Loop?

  - by o7th Web Design

  I have a pretty great SqlDataReader wrapper in which I can map the output into a strongly typed list. What I am finding now is that on larger datasets with larger numbers of columns, performance could probably be a bit better if I can optimize my mapping. In thinking about this there is one section in particular that I am concerned about as it seems to be the heaviest hitter: while (_Rdr.Read()) { T newObject = new T(); for (int i = 0; i <= _Rdr.FieldCount - 1; ++i) { PropertyInfo info = (PropertyInfo)_ht[_Rdr.GetName(i).ToUpper()]; if ((info != null) && info.CanWrite) { info.SetValue(newObject, (_Rdr.GetValue(i) is DBNull) ? default(T) : _Rdr.GetValue(i), null); } } _en.Add(newObject); } _Rdr.Close(); What I would really like to know, is if there is a way that I can make this loop asyncronous? I feel that will make all the difference in the world with this beast :) Here is the entire Map method in case anyone can see where I can make further improvements on it... IList<T> Map<T> // Map our datareader object to a strongly typed list private static IList<T> Map<T>(IDataReader _Rdr) where T : new() { try { Type _t = typeof(T); List<T> _en = new List<T>(); Hashtable _ht = new Hashtable(); PropertyInfo[] _props = _t.GetProperties(); Parallel.ForEach(_props, info => { _ht[info.Name.ToUpper()] = info; }); while (_Rdr.Read()) { T newObject = new T(); for (int i = 0; i <= _Rdr.FieldCount - 1; ++i) { PropertyInfo info = (PropertyInfo)_ht[_Rdr.GetName(i).ToUpper()]; if ((info != null) && info.CanWrite) { info.SetValue(newObject, (_Rdr.GetValue(i) is DBNull) ? default(T) : _Rdr.GetValue(i), null); } } _en.Add(newObject); } _Rdr.Close(); return _en; }catch(Exception ex){ _Msg += "Wrapper.Map Exception: " + ex.Message; ErrorReporting.WriteEm.WriteItem(ex, "o7th.Class.Library.Data.Wrapper.Map", _Msg); return default(IList<T>); } }

• Sockets: I/O Error 32

  - by Genesis

  Could someone please explain what an I/O Error 32 refers to in the context of a network socket? I have a multithreaded Socks5 server written using Poco SocketReactors and am getting this error when the server load reaches a certain point. The exception is thrown within my onReadable handlers at the same time across all threads which have connections associated with them. The only other thing I am doing within those threads is std::cout but I am not sure if this is a potential cause.

• How can I tell the number of replacements in a formatter string?

  - by sdanna

  Given the following method: (real method has a few more parameters, but the important ones are below...) public string DoSomething(string formatter, params string[] values) { // Do something eventually involving a call to String.Format(formatter, values); } Is there a way to tell if my values array has enough objects in it to cover the formatter, so that I can throw an exception if there aren't (short of doing the string.Format; that isn't an option until the end due to some lambda conversions)?
