A design pattern is not code, per se, but a "plan of attack" for solving a common software development problem. The GOF had distilled the design patterns in their book into three main subject areas: Creational, Structural, and Behavioral.

C# pointers
Can we use pointer in c# ?if we can then how it can implement ?and if no then why we can not use pointer in c#?
hmehta

We can use pointers in C# within the scope of unsafe code e.g.:unsafe{//all pointer related code here}but doing so, makes ur code un managed.Also, if you want to have pointers to class level variables, you must use fixed keyword.

ByteArray Class
Write a class called ByteArray that implement allocating, reading and writing to an array of bytes. The runtime environment has a limitation. The maximum continuous memory size that it can allocated is 64k bytes. It can allocate many 64K ( or less) chunks. The ByteArray class should hide this limitation and support allocating arrays larger than 64K as in the following example :ByteArray ba = new ByteArray...

Reflection is an API that allows programmatically getting access to .Net assembly and module metadata. An assembly is a group of .Net modules, resources and manifest. As a rule assembly is located in one file and has one .Net module.

Is there a way to force garbage collection?
Yes. Set all references to null and then call System.GC.Collect().If you need to have some objects destructed, and System.GC.Collect() doesn't seem to be doing it for you, you can force finalizers to be run by setting all the references to the object to null and then calling System.GC.RunFinalizers().

I was trying to use an "out int" parameter in one of my functions. How should I declare the variable that I am passing to it?
You should declare the variable as an int, but when you pass it in you must specify it as 'out', like the following: int i;foo(out i);where foo is declared as follows: [return-type] foo(out int o) { }

Does C# support properties of array types?
Yes. Here's a simple example: using System;class Class1 {private string[] MyField;public string[] MyProperty {get { return MyField; }set { MyField = value; }}}class MainClass{public static int Main(string[] args) {Class1 c = new Class1();string[] arr = new string[] {"apple", "banana;c.MyProperty = arr;Console.WriteLine(c.MyProperty[0]); // "apple"return 0;}}

What is a delegate?
A delegate object encapsulates a reference to a method. In C++ they were referred to as function pointers.

A typical example of delegate usage can be found in event handling. For example, when the event is raised that the selected index of a dropdown list changed, we want method "ddlFoo_SelectedIndexChanged(object sender, EventArgs e)" to be called.
