I had a question about the "using" statement and Generics in the next
version of C#, and I was directed to this newsgroup. My question is: Will
the following syntax be valid?
using Int32ArrayList = System.GCollect ions.ArrayList< Int32>;
....
Int32ArrayList myArrayList = new Int32ArrayList( );
I (along with many others) use a similar method in C++ with typedefs, and to
me it really makes STL code a lot cleaner. I see no reason why this should
not be possible in Whidbey C#, but I may be missing something. This is of
course a trivial example, but in cases where there are several template
parameters (and even moreso, nesting), it really helps.
I don't have time to install Rotor and Gyro to find out if it works in that
environment, so I thought I'd ask here first.
Thanks in advance,

I heard that they are considering some using alias directives support for
generics for Whidbey.

I'm kinda hoping for some type of inline ILASM block. It would probably be
easiest just to allow one to write the whole function in il, or none of it.
This is kinda what I was thinking:
class Test
{
void Main() {
Console.WriteLi ne(Add(5, 6));
}
// ilasm function
int ilasm Add(int a, int b) {
ldarg.0 // push a on stack
ldarg.1 // push b on stack
add // add 2 args
ret // return int on the stack
}
/*
C# code for the ilasm is here:
int Add(int a, int b) {
return a + b;
}
*/
}

The answer is "yes", you will be able to do that, but note that you do not
get real typedefs out of this. Typedefs define specific types, while aliases
are just shortcuts.

of my antiquated style has been straight-forward. For example:

Why do people spend so much time writing complex generic types?
for fun?
to learn?
for use?
I think of generics like I do about operator overloading.
Great to have as a language-feature, as it defines the language more
completely. Great to use.

I have never used generics before, and I was wondering if the following sort
of use was acceptable/normal for a method:

{
IList<IPerson> personList = new List<IPerson>();

Let say I have 2 methods:
void BeginGroup();
void BeginGroup(string msg);
when I want to refer to them I write

But this cause a compiler warning, where my declaration is ambiguous
(between the 2 BeginGroup methods).
But what if I want to refer them both?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
