C# Language Design: explicit interface implementation of an event
Small question about C# language design :))
If I had an interface like this:
interface IFoo {
int Value { get; set; }
}
It's possible to explicitly implement such interface using C# 3.0 auto-implemented properties:
sealed class Foo : IFoo {
int…

How to call an explicitly implemented interface-method on the base class
I have a situation, where two classes (one deriving from the other) both implement the same interface explicitly:
interface I
{
int M();
}
class A : I
{
int I.M() { return 1; }
}
class B : A, I
{
int I.M() { return 2; }
}
From the derived…

Is the C# "explicit implementation" of the interface present in Java?
In C#, if you have two base interfaces with the same method (say, F()) you can use explicit implementation to perform different impl. for F(). This alloes you to differently treat the object, corresponding to the current point of view: as…

In C#, why do interface implementations have to implement a another version of a method explicitly?
Take this example:
public interface IFoo
{
IFoo Bar();
}
public class Foo : IFoo
{
public Foo Bar()
{
//...
}
IFoo IFoo.Bar() { return Bar(); } //Why is this necessary?
}
Why is the implicit implementation of IFoo…

How can I access an explicitly implemented method using reflection?
Usually, I access a method in reflection like this:
class Foo
{
public void M () {
var m = this.GetType ().GetMethod ("M");
m.Invoke(this, new object[] {}); // notice the pun
}
}
However, this fails when M is an explicit…

Is it possible to implement property setter explicitly while having a getter publicly available?
When I define an interface that contains a write-only property:
public interface IModuleScreenData
{
string Name { set; }
}
and attempt to (naively) implement it explicitly with an intention for the property to also have a publicly available…

There are two ways to implement an interface:
interface IMyInterface
{
void Foo();
}
class IImplementAnInterface : IMyInterface
{
public void Foo()
{
}
}
// var foo = new IImplementAnInterface();
// foo.Foo(); //Ok

Why doesn't C# support explicitly implemented virtual methods?
Interface methods in C# can be implemented explicitly, so that their implementation is invoked when an instance is explicitly cast to the interface type. Why is this not also supported on virtual methods of classes?
Although working around the…

Use explicit interface implementations with a dynamic object
I'm experimenting with explicit implentations of interfaces. This is to strip the intellisense with methods which are not valid in the current context.
