Question

I’ve the following code and I can’t fully understand what’s happen there:

Authorize auth = new Authorize(
    this.google,
    (DesktopConsumer consumer, out string requestToken) =>
    GoogleConsumer.RequestAuthorization(
        consumer,
        GoogleConsumer.Applications.Contacts | GoogleConsumer.Applications.Blogger,
        out requestToken));

Here’s what I know:
“Authorize” – have only 1 constructor which accept 2 arguments: (DesktopConsumer, FetchUri).
“this.google” – is a “desktopConsumer” object.
“GoogleConsumer.RequestAuthorization” returns a “Uri” object.

I can’t understand what’s the meaning of the line:
(DesktopConsumer consumer, out string requestToken) =>
in the middle.

Answer 1

In this case => creates an anonymous method/delegate using a lambda expression with the arguments DesktopConsumer consumer, out string requestToken.
