Convention to put every class in its own .cs file - but what about nested classes?

Question

User2110873642 posted

its recommended to put each class in its own .cs file. however, what about nested classes?

like this:

    class DayLogfile
    {
        public List<LogSet> Logs { get; set; } = new List<LogSet>();
        public class LogSet
        {

        }
    }

do you then create these: ?

• DayLogFile.cs
• Daylogfile.LogSet.cs

?

Hi fazioliamboina,

Accroding to your description,I'm guessing that you need to put nested classes into a single .cs file.I suggest you could use partial classes to split the main class and the nested classes. 

Just like this:

DayLogfile.cs:

public partial class DayLogfile
  {
     // Outer class
  }

Daylogfile.LogSet.cs:

public partial class DayLogfile
  {
    private class LogSet
    {
      // LogSet details
    }
  }

Best regards,
