We'll need to add the using directives for system.collections.generic and

system.link to this file.

Using System.Collections.Generic and using System.

Link.

Let's put our search feature to work and

try to figure out what the bird was that I saw the other day.

We can write a little console application that will cycle through each page of

the results until we press a certain key.

So let's hop over to the program.cs file.

First, let's create our search parameters.

var searchParameters= new BirdSearch.

So we'll use object initialization here.

And so the bird was Size = medium and

The country was the United States and

the colors we have to give

it a new list of string and

the colors were White,

Brown and Black.

Okay, and then the page will give it zero to start out.

And the page size will give it, what did I say earlier a five, all right.

So we've got our search parameters.

Let's write something to the console so they know what's going on.

Console.WriteLine Type any key to begin search.

Kinda like a go button, right?

All right, now we're gonna need a loop to loop through our results.

While Console.ReadKey,

so that'll read only one key at the console.

And it has a property called KeyChar.

And if that is not equal to q, we'll say.

Okay.

So this loop is going to keep looping and

reading a key from a console until somebody presses a q.

First, let's write out something to the console.

I'm going to use a new feature of c sharp instead of using

string.format like we have in previous videos.

I'm gonna use a dollar sign, then a string quote.

Inside here, I'm gonna say Page colon, and open close curly braces.

So when I put this dollar sign right here, inside the curly braces,

I can put in code.

So we'll use our searchParameters .Page.

So we're going to let whoever's at the console know what page they're on.

Then, I think we need to use our search on birds but

we don't have a list of birds so we'll create a new var

birds one last time = BirdRepository.LoadBirds.

Okay, and now we can call our search method .search and

we'll pass it the searchParameters search parameters And

then will just well call ToList put it in a list and

there's an other method I wanna show you called ForEach.

And what this does we can pass it on lambda.

goes to and what that does is run a piece of code for every element in the list.

So for each b in birds,

let's write out to the console, console.WriteLine.

And we'll do that magic string mashing thing again.

We'll start out with a dollar sign.

I like to go ahead and quote, quote end my method just so

I don't have any syntax errors.

So in here we're going to write the name of the bird Common Name

equals and then we need our curly braces.

So that's b.CommonName because our b Is our input parameter for a lambda.

All right, and we need to close out the for each method.

So while this is looping, it's not gonna change the page.

We need to change the page after every time we print them out to the screen.

So let's search parameters every time we loop through, we'll add to the page.

Page, plus plus.

So, we'll add one to the page property.

Okay.

So I think we can go ahead and compile this guy.

So we're going to compile on the console with mcs.

All of our files with star.cs.

Then we're gonna specify the out argument and we're gonna give it Program.exe.

So that it'll compile all our files and give us an executable called

Program.exe, we've got an error.

Bird search extension.cs.

Let's go check that out.

Line 22 oops looks like we've got a couple of typos here

where s.size and search should have been an a in it.

Did you catch that before I did?

All right, we'll save that file and we'll try it again.

Okay.

BirdSearchExtension, the name page does not exist.

That's line 29.

Ha.

I put in just random variable names here.

This should be search.Page and

this should be search.PageSize,

okay, and search.PageSize.

All right, let's try to compile again.

All right great, so now we can run

this with mono Program.exe.

Okay, type any key to begin search.

All right, there's our first page could be any of those.

[LAUGH] All right.

2, 3. It looks like we've run out of

bird results.

Now, I'll press q to exit.

Awesome.
