Description

The avrogen tool for C# fails to map the namespaces of inner records.

Example:

{
  "type": "record",
  "name": "ExampleRecord",
  "namespace": "com.example",
  "fields": [
    {
      "name": "Id",
      "type": "string",
      "logicalType": "UUID"
    },
    {
      "name": "InnerRecord",
      "type": {
        "type": "record",
        "name": "InnerRecord",
        "fields": [
          {
            "name": "Id",
            "type": "string",
            "logicalType": "UUID"
          }
        ]
      }
    }
  ]
}

Command:

avrogen -s ./example.avsc ./dotnet --namespace "com.example:Example" 

Result:

namespace Example
{
   using System;
   using System.Collections.Generic;
   using System.Text;
   using Avro;
   using Avro.Specific;
   
   public partial class ExampleRecord : ISpecificRecord
   {
      public static Schema _SCHEMA = Avro.Schema.Parse("{\"type\":\"record\",\"name\":\"ExampleRecord\",\"namespace\":\"com.example\",\"fields\":[{\"nam" +
            "e\":\"Id\",\"type\":\"string\"},{\"name\":\"InnerRecord\",\"type\":{\"type\":\"record\",\"name\":\"I" +
            "nnerRecord\",\"namespace\":\"com.example\",\"fields\":[{\"name\":\"Id\",\"type\":\"string\"}]}}" +
            "]}");
      private string _Id;
      private com.example.InnerRecord _InnerRecord;
      public virtual Schema Schema
      {
         get
         {
            return ExampleRecord._SCHEMA;
         }
      }
      public string Id
      {
         get
         {
            return this._Id;
         }
         set
         {
            this._Id = value;
         }
      }
      public com.example.InnerRecord InnerRecord
      {
         get
         {
            return this._InnerRecord;
         }
         set
         {
            this._InnerRecord = value;
         }
      }
      public virtual object Get(int fieldPos)
      {
         switch (fieldPos)
         {
         case 0: return this.Id;
         case 1: return this.InnerRecord;
         default: throw new AvroRuntimeException("Bad index " + fieldPos + " in Get()");
         };
      }
      public virtual void Put(int fieldPos, object fieldValue)
      {
         switch (fieldPos)
         {
         case 0: this.Id = (System.String)fieldValue; break;
         case 1: this.InnerRecord = (com.example.InnerRecord)fieldValue; break;
         default: throw new AvroRuntimeException("Bad index " + fieldPos + " in Put()");
         };
      }
   }
}

 

In this case the InnerRecord is referenced via "com.Example.InnerRecord", but it should be "Example.InnerRecord".
