ABOUT ME

Take .NET Interoperability…… slice it to ribbons…… and then glue it all back together

AGENDA

WHAT’S WRONG WITH .NET INTEROPERABILITY?

Part 1

Strong Type

IEnumerable<T>

foreach

for (int i = 0; i < foos.Count(); i++){

Foo f = foos.ElementAt(i);// Do something

} 

foreach (Foo f in foos)

{

// Do something

}

for (int i = 0; i < foos.Count(); i++){

Foo f = foos.ElementAt(i);// Do something

} 

foreach (Foo f in foos)

{

// Do something

}

DON’T DO THIS

FOR i := 0 TO Foos.Count - 1 DO BEGIN Foo := Foos.Item(i);END;

DO THIS INSTEAD

Enumerator := Foos.GetEnumerator;WHILE Enumerator.MoveNext DO BEGIN Foo := Enumerator.Current;END;
