.NET Forum / .NET Framework / New Users / October 2007say 10 most important classes in framework
<sorry for my bad english> hello, I am lerning (and working with) .net from some time and I want you to enumerate to me 10 most important (most useful) clasess (classes to specialy good remembering by .net programmer) from framework meybe without some obvious classes such as fundamental types and collections - also I am not thinking for such stright clases as most useful controls or IO clases etc ) I ve got a eight examples from my side - aplication, environment, process, control, form, timer, component, container - could somebody assembly some list for me. More lists better. thanks JS In your case the most important class is an English language class! You say you don't want fundamental classes and then go on to list 8 fundamental classes. > <sorry for my bad english> > [quoted text clipped - 12 lines] > thanks > JS Stephany, >In your case the most important class is an English language class! I fail to see why that should be the top priority for someone who probably lives in Poland.

PS. Could someone of You maybe advice me some nicer looking than usenet news gate? Www Gate to read and write to wide english-language usenet groups? I would appreciate. JS This question can't really be answered definitively. If you live and breath databases, then I've got a bunch of classes that will be most important to you. If you are a UI designer, then I've got others that you will use all the time. There are literally thousands and thousands of classes in the .NET Framework, narrowing it down to the 10 most important is not really a valid question in the first place. First figure out what it is you need to do and then go from there. > <sorry for my bad english> > [quoted text clipped - 12 lines] > thanks > JS > hello, I am lerning (and working with) .net from some time > and I want you to enumerate to me 10 most important (most useful) [quoted text clipped - 3 lines] > fundamental types and collections - also I am not thinking for such > stright clases as most useful controls or IO clases etc ) It's not clear to me where the line should be drawn - you want the 10 most important classes, but not including the fundamental ones.

In > other words, the most important ones which aren't really important... You know - I ' am curious to which classes to focus on when I learn a fundamentals of framework - simple types like int or string though fundamental are not what I am asking about becouse they are obvious. I am looking into this terrible (from some points of view) msdn and realy do not know what is more important > Without the restriction, I'd go for (off the top of my head): > > object > string > Delegate > Enum those above are smple fundamental, so i do not count can you maybe put yet a few more for me ? :) > ValueType > Stream > List<T> > Dictionary<K,T> > Convert > Math tnx JS > > It's not clear to me where the line should be drawn - you want the 10 > > most important classes, but not including the fundamental ones. In [quoted text clipped - 6 lines] > into this terrible (from some points of view) msdn and > realy do not know what is more important The most important ones *are* the fundamental ones. As they become "less fundamental" they will become less important. Beyond the ones that I mentioned, it will depend on what you're doing. To access a database, you ought to know about DataReader, DataSet, DataTable, DataRow, along with the connection and parameter types which are relevant to your particular database. If you're looking at Windows Forms there are a whole bunch of classes there for controls etc. If you're writing an HTML web application, there are controls, sessions etc. If you're writing a web service, you need to know about different things again. It's hard to get more specific without more context, given that you've tried to rule out fundamental types. Jon IMO don't focus on specific classes. Just deal with what you have to deal with as you go possibly asking for specific questions. You could start by checking namespaces at : http://msdn2.microsoft.com/en-us/library/aa388745.aspx Or by technology at : http://msdn2.microsoft.com/en-us/library/63bf39c2.aspx Also the web browser in VS.NET allows to quickly browse classes to check for what could interest you... >> It's not clear to me where the line should be drawn - you want the 10 >> most important classes, but not including the fundamental ones.
