I've just installed resharper and it's letting me know the namespaces i'm not actually using in each of my classes. which lead me to the question - is there actually any overhead in leaving these, unused, using declarations in? is it just a matter of tight code, or is there a performance hit in invoking these namespaces when i don't ne...

Say I have these two objects: OracleConnection connection = new OracleConnection(connectionString); OracleCommand command = new OracleCommand(sql, connection); To close the connection or Oracle, do I have to call command.Dispose(), connection.Dispose(), or both? Is this good enough: using(connection) { OracleDataReader reade...
Hello! I am still learning C++ and I have never really created my own namespaces before. I was experimenting with them and while I got most things to work, there's one thing that I still can't seem to do. I would like to be able to call a static method within a class without typing something like "NameOfClass::method." Here is what I...
Would really like to be able to decorate my class with an attribute of some sort that would enforce the use of a using statement so that the class will always be safely disposed and avoid memory leaks. Anyone know of such a technique? ...
So a using statement automatically calls the dispose method on the object that is being "used", when the using block is exited, right? But when is this necessary/beneficial? For example let's say you have this method: public void DoSomething() { using (Font font1 = new Font("Arial", 10.0f)) { // Draw some text here ...
I'm adding some code into a using block in a C# program. I'm sort of stuffing my app, which previously was a standalone into an existing body of code, so I need to do a bit of messing around to get it to fit properly. What it's ending up looking like is the following: public class WrapperForMyOldApp { public static ItemThatINeed ...

Hello, I'm new to C#,been a pascal lover until I found C# in Depth.In Delphi there is a try{} statement that is also implemented in C#. However,I've seen some of you mentioning "Using(){} is better than try{}". Here's an example: //This might throw an exception sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, Pr...
I am wanting to create an internal messaging system that can tell me the duration of some code being called. I was thinking for ease of use, to make the SystemMessage class implement IDisposable. I would set a time stamp during the SystemMessage's constructor and if the Dispose was called, I could figure out the duration. The prob...

In MySQL, you can use the keyword USING in a join when you join on columns from different tables with the same name. For example, these queries yield the same result: SELECT * FROM user INNER JOIN perm USING (uid) SELECT * FROM user INNER JOIN perm ON user.uid = perm.uid Is there an equivalent shortcut in SQL Server? ...

If I have the following situation: StreamWriter MySW = null; try { Stream MyStream = new FileStream("asdf.txt"); MySW = new StreamWriter(MyStream); MySW.Write("blah"); } finally { if (MySW != null) { MySW.Flush(); MySW.Close(); MySW.Dispose(); } } Can I just call MySW.Dispose() and skip the Close ev...
DataSet and DataTable both implement IDisposable, so, by conventional best practices, I should call their Dispose() methods. However, from what I've read so far, DataSet and DataTable don't actually have any unmanaged resources, so Dispose() doesn't actually do much. Plus, I can't just use using(DataSet myDataSet...) because DataSet ha...
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...
I've run ildasm to find that this: using(Simple simp = new Simple()) { Console.WriteLine("here"); } generates IL code that is equivalent to this: Simple simp = new Simple(); try { Console.WriteLine("here"); } finally { if(simp != null) { simp.Dispose(); ...
