Debug vs Release
Debug
code is not optimised, used by developers. Stack trace information will be very specific and contains all methods to reach the error point.
Release :
Fast.
Stack trace will be Nil.
in Release the following code wont get hit
#if DEBUG
Console.WriteLine("Somethings");
#endif
some more information:
#if DEBUG: The code in here won't even reach the IL on release.[Conditional("DEBUG")]: This is a method Attribute. This code will reach the IL, however calls to the method will be omitted unless DEBUG is set when the caller is compiled.
Delegates:
https://www.youtube.com/watch?v=AVHk97amJ4I
namespace HelloWorld
{
public delegate void MyDelegat_XX (string Name);
public class _DelegateClass
{
public MyDelegat_XX myDel_XX;
}
class ProgramClass
{
static void Main(string[] args)
{
// In
Delegates, we can assign and invoke the delegate out the
//class
(ProgramClass) where the delegates is declared-(_DelegateClass)
_DelegateClass newClassOjb = new _DelegateClass();
newClassOjb.myDel_XX = Print_Method;
newClassOjb.myDel_XX("Pradeep Kumar");
}
static void Print_Method(string Name)
{
Console.WriteLine(Name);
}
}
}
Events & Delegates:
Events is the abstration layer over the delegate
namespace HelloWorld
{
public delegate void MyDelegat_XX (string Name);
public class _DelegateClass
{
//use
event before the Delegate to add encapuslation to the delegate
public event MyDelegat_XX myDel_XX;
public void _InvokeXX_Method()
{
myDel_XX("MyNameIsPradeep");
}
}
class ProgramClass
{
static void Main(string[] args)
{
//1.
After adding event keyword, we cannot assign to or invoke delegate
// We
can only add/ remove method
_DelegateClass newClassOjb = new _DelegateClass();
//2 We
can add or remove a method
newClassOjb.myDel_XX +=
Print_Method;
newClassOjb.myDel_XX +=
Display_Method;
newClassOjb._InvokeXX_Method();
Console.WriteLine("----------------------------------");
newClassOjb.myDel_XX -=
Display_Method;
newClassOjb._InvokeXX_Method();
}
static void Print_Method(string Name)
{
Console.WriteLine(Name);
}
static void Display_Method(string Name)
{
Console.WriteLine(Name+"
From Display Method");
}
}
}
Generic Example
class Program
{
static void Main(string[] args)
{
MyClass<int> vb1 = new MyClass<int>();
Console.WriteLine(vb1.Call(112));
MyClass<string> vb2 = new MyClass<string>();
Console.WriteLine(vb2.Call("Hello"));
}
}
class MyClass<xyzName>
{
public xyzName Call(xyzName vb)
{
return vb;
}
}
Interface Example:
class InterfaceExample
{
public void Method()
{
IFirst tc1 = new TestClass();
ISecond tc2 = new TestClass();
tc1.Show();
tc2.Show();
}
}
public interface IFirst
{
void Show();
}
public interface ISecond
{

public class TestClass : IFirst, ISecond
