No mapping properties for type when trying to write a file and using attributes.

[Temeos]

I am trying to write into a csv file by using Attributes.
I maybe should mension, that i am working in Unity.
This is my code:
public class Log
{
[Index(0)]
[Name("Average Time")]
public float timeAverage;
[Index(2)]
[Name("Tries")]
public float numberOfTries;
[Index(1)]
[Name("TPT")]
public flaot averageTimePerTry;
}

public void MakeFile(Log log)
{
using (var writer = new StreamWriter(Application.dataPath + "/Logs/logFile.csv"))
using (var csv = new CsvWriter(writer, CultureInfo.InvariantCulture))
{
csv.WriteRecord<Log>(log);
}
}
So this gives me the error "No properties are mapped for type..."

I also tried to use the ClassMap method and it worked, but i didn't have any headers. The code looked like this:
public class LogFileMap : ClassMap<Log>
{
public LogFileMap()
{
Map(m => m.timeAverage).Index(0).Name("Average Time");
Map(m => m.numberOfTries).Index(1).Name("Number of tries");
Map(m => m.averageTimePerTry).Index(2).Name("Time on one Try");
}
}
with the addidtion of csv.Configuration.RegisterClassMap<ClassMap>(); in the MakeLog() function.

If possible, i would like to know how to do this with the Attributes. But i will also be thankful for a fix in the ClassMap method.

Best regards.

Hi, did you find an answer to your issue ? Else, I recommand you to add getters and setters to your properties:

public class Log
{
    [Index(0)]
    [Name("Average Time")]
    public float TimeAverage { get; set; }

    [Index(2)]
    [Name("Tries")]
    public float NumberOfTries { get; set ; }

    [Index(1)]
    [Name("TPT")]
    public float AverageTimePerTry { get; set; }
}

Or use fluent ClassMap and remove Log class annotations but keep the getters and setters.

This is configurable for CsvHelper, so if you need to keep them fields configure the writer to map fields, see these comments on an issue from 2018.

But that said, I agree with @remymantei. The convention for most .NET/C# code is: properties are serialized, while fields are not, even public fields. If possible it would be better to switch your code to follow the platform conventions.
