We'll use the new Bird Search Extension to find the bird I saw.
We'll need to add the using directives for
system.collections.generic and
0:00
system.link to this file.
0:05
Using System.Collections.Generic and
using System.
0:09
Link.
0:20
Let's put our search feature to work and
0:23
try to figure out what the bird
was that I saw the other day.
0:25
We can write a little console application
that will cycle through each page of
0:29
the results until we press a certain key.
0:33
So let's hop over to the program.cs file.
0:36
First, let's create our search parameters.
0:41
var searchParameters= new BirdSearch.
0:45
So we'll use object initialization here.
0:52
And so the bird was Size = medium and
0:59
The country was the United States and
1:06
the colors we have to give
1:13
it a new list of string and
1:18
the colors were White,
1:23
Brown and Black.
1:27
Okay, and then the page will
give it zero to start out.
1:32
And the page size will give it,
what did I say earlier a five, all right.
1:40
So we've got our search parameters.
1:49
Let's write something to the console so
they know what's going on.
1:53
Console.WriteLine Type
any key to begin search.
1:56
Kinda like a go button, right?
2:03
All right, now we're gonna need
a loop to loop through our results.
2:09
While Console.ReadKey,
2:13
so that'll read only
one key at the console.
2:18
And it has a property called KeyChar.
2:22
And if that is not equal to q, we'll say.
2:26
Okay.
2:33
So this loop is going to keep looping and
2:35
reading a key from a console
until somebody presses a q.
2:38
First, let's write out
something to the console.
2:44
I'm going to use a new feature
of c sharp instead of using
2:48
string.format like we
have in previous videos.
2:53
I'm gonna use a dollar sign,
then a string quote.
2:56
Inside here, I'm gonna say Page colon,
and open close curly braces.
3:01
So when I put this dollar sign right here,
inside the curly braces,
3:10
I can put in code.
3:14
So we'll use our searchParameters .Page.
3:16
So we're going to let whoever's at
the console know what page they're on.
3:21
Then, I think we need to
use our search on birds but
3:28
we don't have a list of birds so
we'll create a new var
3:33
birds one last time =
BirdRepository.LoadBirds.
3:40
Okay, and now we can call our
search method .search and
3:49
we'll pass it the searchParameters
search parameters And
3:54
then will just well call
ToList put it in a list and
4:00
there's an other method I
wanna show you called ForEach.
4:05
And what this does we
can pass it on lambda.
4:12
goes to and what that does is run a piece
of code for every element in the list.
4:16
So for each b in birds,
4:24
let's write out to the console,
console.WriteLine.
4:28
And we'll do that magic
string mashing thing again.
4:32
We'll start out with a dollar sign.
4:38
I like to go ahead and quote,
quote end my method just so
4:41
I don't have any syntax errors.
4:44
So in here we're going to write
the name of the bird Common Name
4:46
equals and then we need our curly braces.
4:53
So that's b.CommonName because our b
Is our input parameter for a lambda.
4:55
All right, and
we need to close out the for each method.
5:06
So while this is looping,
it's not gonna change the page.
5:14
We need to change the page after every
time we print them out to the screen.
5:18
So let's search parameters every time
we loop through, we'll add to the page.
5:23
Page, plus plus.
5:32
So, we'll add one to the page property.
5:32
Okay.
5:36
So I think we can go ahead and
compile this guy.
5:38
So we're going to compile
on the console with mcs.
5:41
All of our files with star.cs.
5:44
Then we're gonna specify the out argument
and we're gonna give it Program.exe.
5:47
So that it'll compile all our files and
give us an executable called
5:56
Program.exe, we've got an error.
6:00
Bird search extension.cs.
6:05
Let's go check that out.
6:07
Line 22 oops looks like we've
got a couple of typos here
6:11
where s.size and
search should have been an a in it.
6:16
Did you catch that before I did?
6:22
All right, we'll save that file and
we'll try it again.
6:23
Okay.
6:30
BirdSearchExtension, the name
page does not exist.
6:33
That's line 29.
6:38
Ha.
6:40
I put in just random variable names here.
6:41
This should be search.Page and
6:48
this should be search.PageSize,
6:54
okay, and search.PageSize.
7:02
All right, let's try to compile again.
7:09
All right great, so now we can run
7:15
this with mono Program.exe.
7:20
Okay, type any key to begin search.
7:24
All right, there's our first
page could be any of those.
7:28
[LAUGH] All right.
7:31
2, 3.
It looks like we've run out of
7:36
bird results.
7:38
Now, I'll press q to exit.
7:40
Awesome.
