thanks for the info. i also think it is alias. if any other difference there please tell me. let me know that..

Int32 v = 5;
Console.WriteLine(v);
What is the output?
Please send the output to my mailId.

One Small correction.System.Int32 is a structure. Not a class.

thanks for the good explanation for difference between string and String in c#

thanks for the good explanation for difference between string and String in c#

To gain more control over string initialization, declare a variable using the System.String data type and create a new instance using the new keyword. The System.String class contains several constructors that you can use to initialize the string value. There is no recommendation on whether you use the string keyword or the System.String class. The string keyword is simply an alias for this class, so it is all a matter of taste. We prefer using the string keyword, but this preference is purely aesthetic. For this reason, we simply refer to the System.String class as the string class or data type.

Then what is the use of using the aliases.

The info. is really useful. Pls. correct the typing mistake in the last statement.

When you declare an int in C#, what you are actually declaring is an instance of a .Net struct, System.Int32.

Thanks, I was wondering when i was not able to inherit System.Int32 class in my enumeration but when i inherit from int its working. This was very much useful in my project.

As my another friend had said that \"When you declare an int in C#, what you are actually declaring is an instance of a .Net struct, System.Int32.\" then How will i be able to inherit for int which is working.

int i;
int32 i:
both are same or not?

if both are not same what is the differcence?

please send reply.

Thanking you

int in 64 bit is int64
int in 32 bit is int32
if you want to use 32 bit int value in 64bit OS, you must define as int32.

@Netman

Ehh no, in .NET, byte is always 8 bits, char and short are always 16 bits, int is always 32 bits, and long is always 64 bits.
It is void* that is 32 bits on a 32 bit platform and 64 bits on a 64 bit platform.

what is the difference between int16,int32,int64

The difference is in how much they can store. Here is the value range of each (considering they\'re unsigned integers):

Int16: -32,768 to 32,767
Int32: -2,147,483,648 to 2,147,483,647
Int64: -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807

thanks for the information that it is alias one.

Guys,
How does Int32 and Int behaves in 64 bit OS and in 32 Bit OS

test

Good and straight explanation there! Thank you

Is int32 and smallint same?
I have used int as a datatype in my backend and int32 in my frontend asp.net ,but when user itrying to create a new user it gives error in application so i suppose int32 shuold be changed to int64 ?
Please help

I m confuse that as objets are allocated in heap while int type allocated in stack, as Int32 is a Class and its alias is int.
int x=10;
it means x is the variable of class type Int32 so why x is allocate memory in Stack instead of Heap as Int32 is class.

Int 32 is not class but Struct and as It is Value Type it will be allocated in Stack only. Only Reference Types such as Objects of any Class are allocated on stack and their refrences are allocated in Heap.

short is pseudonym of Int16
int is pseudonym of Int32
long is pseudonym of Int64

Int16, Int32 and Int64 are all struct, not class. So, obvious why they are in stack and not in heap.
