CsvHelper: no item is displayed for type

Question

I am using CsvHelper 4.0.3 .

I have a nested class defined as follows:

private class CsvLine {
    public string Solution;
    public string Project;
    public string DependsOnProject;
    public string Weight;
    public string DependsOnPackage;
    public string PackageVersion;
}

My .csv file that I want to parse with CsvHelperhas the following field names:

Solution,Project,DependsOnProject,Weight,DependsOnPackage,PackageVersion

Here is my code:

TextReader readFile = new StreamReader(dependenciesCsvFilePath);
var csvReader = new CsvReader(readFile);
IEnumerable<CsvLine> records = csvReader.GetRecords<CsvLine>();

As per the documentation here , the code above should work.

However, when I check records, I see a message No members are mapped for type 'ParentClass+CsvLine'.

I changed the availability CsvLinefrom privateto public, but that didn't matter.

What have I done wrong?

EDIT: I tried to expose the class CsvLineand make it publicly available, but that didn't help either.

EDIT: Nkosi; , records - : " ". CSV , .

:

Solution,Project,DependsOnProject,Weight,DependsOnPackage,PackageVersion

FOD.sln,ABC.DEF,IMS.DEF,1,,
FOD.sln,ABC.DEF,IMS.GHI,1,,
FOD.sln,ABC.DEF,IMS.JKL,1,,

EDIT: ! Nkosi Panagiotis .

Answer 4

There is a simpler solution to the problem, this is just one line of code. You must tell csvhelper to look at your fields.

using (var csv = new CsvWriter(writer))
{
    csv.Configuration.MemberTypes = CsvHelper.Configuration.MemberTypes.Fields;
.....
}
