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,

In the future, please put your code in code tags while posting. Failing to do so causes all the indentation formatting to not be visible. I've put your code in code tags for you.

 

[Skydiver]

Anyway, the answer is because your method ends at line 27, but you are trying to use the parameter out in line 44. If you used indentation properly on your code (and didn't rely on syntax coloring) the problem would be more obvious.

 

[C# learner]

No problem. Still learning how to use this forum also. Where do I find the code tag?

 

[Skydiver]

The code tag button looks like the </> on the toolbar above the textarea where you type in your post.

 

[Skydiver]

Anyway, here's your code reformatted to use more consistent indentation (as well as fix the missing closing parenthesis on line 41):

 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 recordLine;
 
    string path = (@"C:\Users\steve\OneDrive\Documents\Donna's Documents\Steves stuff\Family Tree Development Folder\GEDCOM Individual Data.csv");
    using StreamReader id = new StreamReader(path, true);
    {
        while ((recordLine = id.ReadLine()) != null)
        {
            // using the split method to parse "line" into lineParts array
            string[] lineParts = recordLine.Split(',');
            //string trimIndividualID = null;

As to the code tags I will try to do this properly in the future sorry. I'm studying the code now thank you.

 

[C# learner]

I went back and double checked the indentation and corrected any errors. Still getting the same error and is underlining the "idIndividualID" field in red. Could it be a problem with the call to the method?

 

[C# learner]

To clarify the "idIndividualID field is underlined red at the if statement only, not the input parameter.

You might want to look at how you are evaluating your conditional and the way you are using the '=' operator...

Thank you for the suggestion. I used one "=" and "==" and still get the same results?? I know it is something simple but can't put my finger on it yet.

 

[Skydiver]

Yes, because as I said your method is only actually just lines 1-26 of post number #6. The scope of a parameter is only within a method. If you want your method to be all of lines 1-57, you need to delete lines 26 and 27.

Or in other words you currently have something that looks like

void DoSomething(string input)
{
   Console.WriteLine(input);
}
{
    Console.WriteLine(input);
}

input on line 3 refers to the parameter input on line 1. The compiler won't know what to do with input on line 6.

To fix things you'll want:

void DoSomething(string input)
{
    Console.WriteLine(input);
    Console.WriteLine(input);
}

Until you get more C# experience, I highly recommend not using the top level statements feature of C#.

This. I personally dislike top level....but I'm an old head
