Question

if i have a class FooWrapper that takes in a Foo during construction:

Foo foo = new Foo();
FooWrapper fooWrapper = new FooWrapper(foo);

Often, i get an array of Foo’s back from some API

Foo[] foos = _api.GetFoos();

is there anyway for me to build up an array of FooWrappers by passing in the appropriate Foo object without simply looping through each one here?

Answer 1

You can use the Array.ConvertAll method.

FooWrapper[] wfoos = Array.ConvertAll<Foo, FooWrapper>(foos, delegate(Foo foo){return new FooWrapper(foo);});
