I got the exception from confluent Kafka producer like

 Avro.AvroException: GenericRecord required to write against record schema but found Avro.Generic.GenericRecord
\n   at Avro.Generic.DefaultWriter.EnsureRecordObject(RecordSchema s, Object value)
\n   at Avro.Generic.DefaultWriter.WriteRecord(RecordSchema schema, Object value, Encoder encoder)
\n   at Avro.Generic.DefaultWriter.Write(Schema schema, Object value, Encoder encoder)

\n   at Avro.Generic.DefaultWriter.Write(Schema schema, Object value, Encoder encoder)
\n   at Avro.Generic.DefaultWriter.WriteRecord(RecordSchema schema, Object value, Encoder encoder)

please find the implementation code.

var s = (RecordSchema)RecordSchema.Parse(
                @{
  "name": "StaticDataNotification",
  "type": "record",
  "namespace": "KafkaName",
  "fields": [
    {
      "name": "UniqueID","type": "string"
    },
    {	  
      "name": "DataList",
      "type": {
        "type": "array",
		"items":{
		"name": "DataList_record",
		"type":"record",
          "fields": [
            {
              "name": "FieldName","type": "string"
            },
            {
              "name": "OldValue","type": "string"
            }
          ]
        }
      }
    }
  ]
}

var child = (RecordSchema)RecordSchema.Parse(
                @{
		"name": "DataList_record",
		"type":"record",
          "fields": [
            {
              "name": "FieldName","type": "string"
            },
            {
              "name": "OldValue","type": "string"
            }
          ]
        }

C# Implementation

var recordStaticData = new GenericRecord(s);
recordStaticData.Add("UniqueID","123456");

List<GenericRecord> genericRecords = new List<GenericRecord>();

for (int i = 0; i < 3; i++)
{
GenericRecord StaticList = new GenericRecord(child);
StaticList.Add("FieldName", "Name");
StaticList.Add("OldValue", i.ToString());
genericRecords.Add(StaticList);
}
recordStaticData.Add("DataList",genericRecords.ToArray());

var dr = producer.ProduceAsync("Topic", new Message<string,GenericRecord>{ Key = System.Guid.NewGuid().ToString("N"), Value = recordStaticData });

I found this solution from google. But its not suit this problem,
