Good,thanks ...

you said " on second and next calls you simply replace the instance of an object with another instance, and it makes the previous instance unreachable and then — everything goes like in the previous case."
but the object reference is not set to the instance of the object??
Then how it replace the instance??Both are same reference?And only one instance.. right??

B objb; //This will allocate memory ??
objb=new B() //What it will do??

exactly you proved...Thanks..

Thanks,
now it is more clear..
Now i got it.Because run time it will be direct memory location like low level program like 8085 programming..
Or we can say machine dependent code to the corresponding processor architecture.

I am thinking in this way, when we are declaring any variable the compiler is having a table to hold the reference value to memory with the name of the variable. So if we are taking or getting that variable table by using this reference we can get the name of the variable.

My friend said it is possible in Python.Then Why not in C#??
Thats why??

Thanks...

Sorry,
Think in this way, The AutoTransmission is possible for most of the car.So we cant able to predict which car is using autoTransmission.
The name of the car is actually the object name.So i want to get the name of object inside the same class itself.

Yes

I am sorry master...please forgive me..

This thing i tried already... thats why i given the question??(I made the mistake first...)
Everybody asking tough questions, So i made it is simple...

good...Dont feel that this is a simple question, may be people will make mistakes...

just conside i have a petrol car


class petrol:car
{
}
class car
{
private :carbody
protected:engine
public:steering
}

if the 'petrol' is inheriting from 'car'

the car is having 'carbody' also...

do u think that the car doesn't have carbody???

I am saying a derived class inherits the private members of a base class also.

Yes.

I am not asking is it visible or not..simply inherit or not??
Sure.?Check in MSDN itself again and confirm it...

If somebody asking the question means, they are expecting some answer.They thinking that ," others can understand what i suppose to mean ".

I am new to this.. thats why??

Did you felt the question is poor..??

How we can able to use GC and if we are defining Collect() method then what are the things we have to make sure..

answer is fine... i am new to this fourm..

Thanks,
But the garbage collector can understand, it will be use or not??
Or a programmer has to collect it??

I think you are correct...rounding error...

The answer is fine.I also given how to rectify it in different method..But i need to know how the compiler is doing the job for this or what is happening in background..??

it is not the problem with conversion of string to double..because it is printing exact value..
d=44.22 //double

doll=44 //int ,now there is no fractional part...

d-doll //(44.22-44) should be .22 but the result is .219999999999986


question is that how the value is loosing... data is exact...

I think may be you are wrong with the concept,even i didn't confirmed....

what i did is that i made a sample class like,

namespace SampleClassInit
{
class SampleClass
{
int x = 55;
int y = 92;
public int MethodAdd()
{
Console.WriteLine("Sample class..");
return 1;
}
}
}

and then i checked the code in ildasm assembler for the low level IL code..
So i found this ....

//IL code...

.ctor:void() method //i think this is the default constructor..

when i explore this method i seen in this way...

.method public hidebysig specialname rtspecialname
instance void .ctor() cil managed
{
// Code size 24 (0x18)
.maxstack 8
IL_0000: ldarg.0
IL_0001: ldc.i4.s 55 //In here X it is initializing
IL_0003: stfld int32 SampleClassInit.SampleClass::x
IL_0008: ldarg.0
IL_0009: ldc.i4.s 92 //In here Y it is initializing
IL_000b: stfld int32 SampleClassInit.SampleClass::y
IL_0010: ldarg.0
IL_0011: call instance void [mscorlib]System.Object::.ctor()
IL_0016: nop
IL_0017: ret
} // end of method SampleClass::.ctor

Initialization is happened inside this method..
Check it and give me the suggestion...\
Thank you..

when we will create the object, the constructor will be called and initialize the values .Before of that how the variable will be call or initialize??

how the .net or c# is managing it rather than c++??

how the compiler is managing the reference type??
i am saying about memory locations(to store the values as well as retrieve the values)...how the compiler can understand these much location i have to refer for this string??

thanks for the all answers,that is great, i got the clear picture....
one more thing,
Then why they(C# creators) made string as reference type.. why not as value type?

it goes directly means to an address location, so that we never want to bother
about the location..
and int allocating memory directly..and the variable directly holding data rather than pointer type or reference type.
pointer concept is clear for me...

so it will be just like an value type??
even 'int' is also doing the same thing,??
why they dint made string in that way??
so reference wont work over there... perfectly??right>??
thanks for the great explanation...
