Resolved Another issue from a beginner C# programmer.

[C# learner]

I created a method that uses a value parameter to be used to find a record in a file and out parameters. I learned how to get the out parameters initialized, but having trouble with the first parameter, idIndividualID. I don't want to null the field because the value is used in the if statement to find the correct record. Why is the field highlighted in red? Error says " The name idIndividualID does not exist in the current context".

 static void FindIndRecord (string idIndividualID, // field in question
                                          out string idSurname,
                                          out string idGivenName,
                                          out string idBirthDate,
                                          out string idBirthPlace,
                                          out string idMarriageDate,
                                          out string idMarriagePlace,
                                          out string idDeathDate,
                                          out string idDeathPlace,
                                          out string idSex,
                                          out string idChildCode,
                                          out string idParentCode)

                            string[] lineParts = recordLine.Split(',');

Unless you are really intent on rolling your own GEDCOM parser, perhaps use someone else's instead:

GitHub - jaklithn/GedcomParser: Parser of GEDCOM files

Parser of GEDCOM files. Contribute to jaklithn/GedcomParser development by creating an account on GitHub.

github.com

As an aside, that data format looks like something someone who was using PowerBuilder would have created. Maybe in my spare time, I might read up on the origin of the GEDCOM file format.

 

[C# learner]

It's how ancestry.com downloads the family tree.

 

[C# learner]

What is the newest way to delimit a file, comma, space, fixed length, a new way?

 

[Skydiver]

The file format du jour is JSON.

Based my fast GEDCOM reading, apparently GEDCOM 5.5.5 is the de facto standard, so I guess you are stuck with that until GEDCOM 7 takes over.

 

[cjard]

the CSV library, are you talking about the beginning of the program with using statements?

If you installed a library using nuget package manager (typical) or added a reference to one(less typical these days) then yes, you'd using it to provide a shortcut instead of having to declare the full name of its classes

 

[cjard]

What is the newest way to delimit a file, comma, space, fixed length, a new way?

It depends on the other end. What will you do with that data you parsed?

 

[cjard]

Every time I use public or private I get a ton of red underlines. Not using either of them seems to work ok in this case.

Probably you're not using them on a class level item. That's the only place they're valid

 

[cjard]

So what I'm trying to do is basically marry up the two files together

Is the GEDCOM file not a single file?

You have repeated columns btw

 

[C# learner]

Yes

 

[C# learner]

The repeating of those columns is on purpose. The marriage and divorce records happen in both the individual section and the family section. They could be totally different.

 

[cjard]

What will you do with that data you parsed?

 

[C# learner]

When I take the individual file that I created and marry it up to the family file I will use it to give desired results in a web page. I know that this has been done before but I want to show where individuals were born to where thay died.

 

[C# learner]

Is there special consideration if a method calls another method and gets red underline in the second method?

 

[Skydiver]

What is the error associated with the red underline?

As a quick aside, never fully trust Intellisense (e.g. the red underlines). It's usually better to actually compile and see what the actual compiler error is. Intellisense was unreliable for Visual Studio 2012 and earlier when writing C/C++ code. For C#, it was kind of unreliable in VS2010 and earlier and then became pretty reliable except for exotic cases. Lately, with VS2022 17.4.2 and .3 I've been seeing Intellisense also being unreliable for C# again.

Where is the compiler on Enterprise 2022?
