If I have
public class AImplementation:IAInterface { void IAInterface.AInterfaceMethod() { } void AnotherMethod() { ((IAInterface)this).AInterfaceMethod(); } }
How to call AInterfaceMethod() from AnotherMethod() without explicit casting?

Public class....
You can't
Can't you just remove the "IAInterface." from the method signature?
public class AImplementation : IAInterface { public void AInterfaceMethod() { } void AnotherMethod() { this.AInterfaceMethod(); } }
Tried this and it works.. .

But if you make the constructor explicit, this kind of implicit conversion can't happen:
class....

Explicit constructors force your constructors); } // ...

Actually my question is all in the title.
Anyway:
I have a class and I use explicit constructor:
.h
class MyClass { public: explicit MyClass(const string& s): query(s) {} private: string query; }
Is it obligatory or not to put explicit keyword in implementation...

My gcc says:
test.cpp:6: error: only declarations of constructors can be 'explicit'
for the following code:
class foo { public: explicit foo(int); }; explicit....
The explicit keyword is only permitted in the header.
No, it is not.

Output:
B->Hello! from Explicit.
Shouldn't it be:?
A->Hello! from Explicit.
Why doesn't explicit cast (IHello)a call IHello.Hello() from class A? interface IHello { void Hello(); } class A : IHello { public virtual void Hello() { Console.WriteLine...

The output is exactly as expected.
Is located:
If S contains a declaration of an explicit interface member implementation that matches to Hello() will call object B's explicit implementation of Hello.

What are the differences in implementing interfaces implicitly and explicitly in C#?
When should you use implicit and when should you use explicit?
Are there any pros and/or cons to one or the other?

Explicit implentation allows it to only be accessible when cast as the interface itself.
Explicit is when you define.
Implicit is when you define your interface via a member on your class .

That is the question. Is there anything you can do with c++ unions that you can't with c# Explicit structs?

Explicit interface implementation in C# also allows.

With an explicit cast, either you are telling the compiler that you know more; float f = i;
With an explicit primitive conversion, it is likely that the conversion could lose; // explicit (extracts text from....

When you use placement-new is a common reason (the only reason?):
struct foo {}; void* memoryLocation = ::operator new(sizeof(foo)); foo* f = new (memoryLocation) foo(); // note: not safe, doesn't handle exceptions // .. .

I have a dll that contains a templated class. Is there a way to export it without explicit specification?

Answer Snippets (Read the full thread at stackoverflow):
This is the only way to give users to freedom to use any type with the template... .
That is, the library that is using the dll can instantiate the template .
Since the code for templates is usually in headers, you don't need to export the functions at all .
