using Amazon.DynamoDB.DataModel;

public static void Main(string[] args)  {
  Console.WriteLine("Setting up DynamoDB client");

  client = new AmazonDynamoDBClient(RegionEndpoint.USEast1);
  DynamoDBContext context = new DynamoDBContext(client);
  SampleData sample = new SampleData();

  sample.id = "0000";
  sample.name = "ochilab";
  sample.value = "日本語";

  context.Save(sample);
  
}

SampleData.cs

using Amazon.DynamoDB.DataModel;

[DynamoDBTable("DynaTest")]
class SampleData {
  [DynamoDBHashKey(AttributeName = "id")]
  public string id { get; set; }
  [DynamoDBRangeKey(AttributeName = "name")]
  public String name  { get; set; }
