The Object of your Affection

tombrophy · August 13, 2019, 2:21pm

I am trying to print out the name that is giving to sam but the program says:

Program.cs(10,11): error CS0122: 'Profile.name' is inaccessible due to its protection level [/home/ccuser/
workspace/csharp-dating-profile/DatingProfile.csproj]

This is my code if you want to know what I should do to it:

using System;

namespace DatingProfile
{
  class Program
  {
    static void Main(string[] args)
    {
      Profile sam = new Profile();
      sam.name = "Sam Drakkila";
    }
  }
}

The build failed. Please fix the build errors and run
again.

Just keep going. That error message is part of the project. You can’t assign a name that way because the .name property is private. The next couple of steps in the project show you how to assign values to a new profile object by using a constructor.

Explain what this means or if it means anything.

That error is beyond me. Did you change your code somehow? If not I’d refresh your browser. The error seems to be unrelated to your actual code, but I could be wrong.

Ah. Ok. You just need to remove the { }'s around your property assignments inside the constructor. The constructor is a block, but each property is just a statement inside the block:

public Constructor( string prop1, int prop2) //This is just an example. Don't use the name Constructor.
{
  this.prop1 = prop1;
  this.prop2 = prop2;
}

    }

midlindner · August 13, 2019, 7:00pm

Since you now have a constructor in place, you pass arguments to the constructor when you instantiate a new Profile object. Trying to assign properties like this: sam.name = "Sam Drakkila"; still doesn’t work for the same reason it didn’t work earlier. Those properties of the object are private. The constructor method is public though, so we use it to create new instances of the object with its property values passed in as arguments like so:

Profile sam = new Profile("Sam Drakkila", 30, "New York", "USA", "he/him");

The order of the arguments needs to match the order that the parameters appear in the constructor declaration: public Profile(string name, int age, string city, string country, string pronouns = "they/them")

tombrophy · August 13, 2019, 7:06pm

So nothing get printed right.

midlindner · August 13, 2019, 7:08pm

That’s right. At this point nothing should appear in the console. You’ll have to complete the next step to code the ViewProfile() method. Then you’ll be able to print sam's profile to the console.

You have an error message. Did you read it? Then what?
If you identify what stops you then that gives you something to find out more about.
It seems like there are still things that you can do yourself, at least from what you’ve said about it.
It won’t be useful to you to have other people tell you the conclusion of what to do to fix something. The thing to learn is how to reach the conclusion of what to do, isn’t it? So you have to go through all the steps that somebody else would, even if it takes time, especially if it takes time.
