Let's get back to building
our game result class.
0:00
The next field in our
csv is the team name.
0:03
That's pretty easy, it's a string.
0:06
Public string
0:08
TeamName, get, set.
0:13
Then in our read soccer results
method we can just assign
0:19
it to the second element in our array.
0:22
GameResult.TeamName equals values(1).
0:28
Let's see what's next.
0:36
Next we've got our HomeOrAway field.
0:40
You can have two string values,
HomeOrAway.
0:44
We could just store the value as a string,
0:49
but I think there's a better
way to store those values.
0:51
We briefly talked about the enum type
before when we use string.split.
0:55
Let's create an enum to represent
our home or away value.
0:59
Public enum HomeOrAway.
1:08
Home and Away.
1:17
This enum has two possible
constant values Home and Away.
1:20
Each one has a backing integer
starting with zero by default.
1:26
We can also declare other values for
each constant.
1:32
This is typically done when the backing
value has some kind of significance.
1:40
But in our case, it's not necessary.
1:44
We can also change the enum's underlying
type to another integral type.
1:49
For instance, we could use byte.
1:53
You won't typically see this, though.
1:58
It's more common to
leave it as an integer.
2:01
Now, we can create a property
to hold the home or
2:06
away value inside our game result class.
2:09
Public, HomeOrAway.
2:11
HomeOrAway.
2:15
Get set.
2:19
We can go back and parse the home or
away field to our gamers old object.
2:23
We can use the triparse method of the enum
class to parse our string value into
2:28
the enum we declared.
2:32
HomeOrAway, homeOrAway and then if.
2:37
This is gonna be a lot like
our DateTime.TryParse except
2:43
we'll do enum.TryParse.
2:47
Then we'll pass it values 2 and
2:52
then out homeOrAway, and if the parse is
2:57
successful, gameResult.HomeOrAway
gets assigned to homeOrAway.
3:04
At this point, we should change the return
type of this method to a list of game
3:11
result objects,
instead of a list of string arrays.
3:15
List Of GameResult and
3:20
list of GameResult.
3:27
And down here, instead of our
string array, we'll add gameResult.
3:33
Let's set a break point here.
3:37
And we'll see if our parsing is working so
far.
3:42
F5.
3:44
Looking good.
