Hi All,
I am new on this VC.Net platform, So please dont mind to my question.
In VC++ we can use pointers very easily, but i want to know if we can use:
int *ptr = new int[10];
and
char * in VC.net.
If we cant use them whats the alternate option for them. Please explain me
this or provide me link to answers to these question.

Thanks.

This is not the right NG to ask VC question, please post to the VC NG
instead.

That works. There's also a syntax for pointers into .NET objects, which
looks like this:

array<int>^ a = gcnew array<int>(10);
interior_ptr<int> ptr = &a[0];

Ben answered the question already. However, I just wanted to point out that
you may not actually need to create a pointer for your specific needs
anymore. The .Net platform supports passing objects around as references
automatically. For example you can do this:

MyClass class = new MyClass();
object o1 = class;
object o2 = o1;
object o3 = o2;
MyClass class2 = o3;

After that sequence of events class, o1, o2, o3 & class2 will all be
pointing at the exact same instance of MyClass object.

What language are you using? Neither C# nor C++ support implicit downcast.
Also "class" is a keyword in most languages and can't be used as a variable
name.
