What is difference between dispose() & finalize() in c#?how database remotely connected?
udhakal
- Nov 25th, 2008
Dispose is called explicitly by the user whereas finalize is called by garbage collector when ever it assumes to be appropriate.usually we use dispose method to free resources of our custom classes. Dispose can be implemented by using IDISPOSABLE interface

Design Pattern : If your classes use unmanaged resources, you need to implement both Dispose & Finalize. Dispose() is called by user code, that is, the code that is using your class.Finalize/Destr...

Data Structures
Assume you have large set of data, say more than 100,000 elements. Each data element has a unique string associated with it. 1. What data structure has the optimal algorithmic access time to any element when the only thing you know about the element is the unique string associated with it? 2. What is the O() time for access to any element using this data structure? 3. What data structures would you...

Classes are inherit from another class. Basically we are using OOPS for reusability, so inhertiance means deriving new class from base class, it occupies less memory.

How do I do implement a trace and assert?
Use a conditional attribute on the method, as shown below: class Debug{[conditional("TRACE")]public void Trace(string s){Console.WriteLine(s);}}class MyClass{public static void Main(){Debug.Trace("hello");}}In this example, the call to Debug.Trace() is made only if the preprocessor symbol TRACE is defined at the call site. You can define preprocessor symbols on the command line by using the /D switch....
