Yes it's a programming question, but wait a moment, I am NOT asking to solve any problem here, I am asking to select your favourite of 2 options.
I think what they want me to do here at work is disgusting. I have to suck it up anyway, since it's the guy who accepts pull request that tells me to do it, period. But I am curious whether or not I am in good company with my prejudice.
It's about DTO, constructors with zillion of parameters and all private properties.
code I prefer and put in my pull request, with 24 properties (i.e large number of properties)
public class FooDto
{
public T1 Property1 { get; set; }
public T24 Property24 { get; set; }
}
class MyFooClass
{
private T1 property1;
private T24 property24;
public FooDto ToDto()
{
return new FooDto()
{
Property1 = property1,
Property24 = property24,
};
}
}
how I have asked to rewrite the code, feels disgusting to me, but curious how many people share, or dislike, my opinion
public class FooDto
{
public FooDto(T1 value1 , T24 value24)
{
Property1 = value1;
Property24 = value24;
}
public T1 Property1 { get; }
public T24 Property24 { get; }
}
class MyFooClass
{
private T1 property1;
private T24 property24;
public FooDto ToDto()
{
return new FooDto(property1 , property24);
}
}
In his defence he has an argument. If someone use that DTO as well, the compiler will force them to initialise all values.
Though one could counter argument that we got unit test for just that.
At any rate, which of those 2 is your favourite code style?
|
|
|
|
|
Option 1, but I do see the argument for option 2, especially if the properties are mandatory.

Of course, using reasonable defaults would prevent you from having runaway parameter lists for your constructors, and all you have to do is set the properties that need to be changed.

To be honest I'd probably have a separate mapper to do the conversion, but of the 2 I'd go 1, once you're over a handful of parameters in a constructor it gets messy.

When a method has more than, say, four arguments, I strongly dislike it, its author, and the Italian governement.

I thought that was mandatory in Italy, regardless.

I would go for option 1.
I would also look at having some sort of mapping functionality so that the values can be populated 'automatically' by passing the DTO to some form of orchestrator together with the data source to populate it.
The following in option 2 is a huge code smell:
public FooDto(T1 value1 , T24 value24)
I have done this myself in the past but it is generally accepted nowadays that a large number of parameters in a signature is a bad idea.

I fail to see what the big deal is about, but if I get to choose I prefer 1.
I don't like huge constructors, they are slightly more error prone.
|
|
|
|
|
Option 1 because it is cleaner, more understandable and more extensible of the two options.
|
|
|
|
|
Option 1.
Agree that Too much parameters in Option 2 is terrible one. Too much parameters require changes in other places(Ex: Business Logic layer, Code-behind, etc.,) when you need to remove/add parameters later.

Really blow his mind. Make the constructor accept a Tuple instead.

that's a good one! 
in fact it might the easiest way how to go about it.. by that I mean I can implement that with some quick copy paste...
whereas implementing the constructor is going to be manually intensive and bug prone!

Yeah, initialization does not inherently mean useful values, so why force lazy coders to initialize meaningless values?
var dto = new FooDto(actualT1Val,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null);

I think I might add a couple of unit test just like that, for giggle...

I don't mind either option, but I think I like v1 better.
When it comes to long lists of assignments I generally copy/paste back and forth with an instance of Excel.
