Converting to generics

Given the inneficiencies of ArrayList and Hashtable on 64-bit systems, I
am converting them to List<and Dictionary<resp ectively. It's a
pretty massive system, so there are a lot of casts. For instance.

ArrayList aaa = new ArrayList();
aaa.Add(new Customer());
aaa.Add(new Customer());
aaa.Add(new Customer());

Customer c = (Customer) aaa[0];

With generics, it would be like this:

List<Customeraa a = new List<Customer>( );
aaa.Add(new Customer());
aaa.Add(new Customer());
aaa.Add(new Customer());

Customer c = aaa[0]; //e.g. without the cast

But, given that I simply changed declarations from ArrayList to List<>,
there is still a lot of code that has a cast, even though the cast is
from a strongly typed list:

Customer c = (Customer) aaa[0];
So changing declarations to generics was pretty easy, but the there are
about a zillion casts in the system. So I have 2 questions.

1. Is the compiler smart enough take out the unnecessary casts?
2. Is there a setting in VS2005 that will show me the unnecessary casts
when compiling?

Thanks.

ReSharper displays unneeded casts as warnings.

I need to initialise a typed parameter depending of its type in a generic class. I have tried to use the C++ template form as follow, but it doesn't work. It seems to be a limitation of generics vs C++ templates. Does anyone knows a workaround to do this ? Thx : public class C<T> { private T myValue;

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 am converting (attempting) some vb6 code that makes vast use of interfaces. One of the major uses is to be able to split out Read-only access to an obect.

Hello! Exception handling in generics seems to be a bit inconsistent to me. Imagine, I have "MyOwnException" class derived from "ApplicationException". I also have two classes "ThrowInConstructor" and "ThrowInFoo". First one throws "MyOwnException" in constructor, second one in "Foo()" method. There is a "GenericCatch" generics class able to accept "ThrowInConstructor" and "ThrowInFoo" as type parameter "<T>". There are two methods in...

I'm building a C# interface to an existing messaging system. The messaging system allows values of several types to be sent/recieved over the interface. What I want to do is use a generic class to produce values in the system. For instance I could create class MsgGenericValue<UInt16>() which would represent an unsigned value on the interface.

Overview: 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,...
