Я работаю в DyanmoDB.В моем проекте я должен динамически задавать имя базы данных и динамически загружать базу данных. Это мой код

 using UnityEngine; using System.Collections; using Amazon.DynamoDBv2.DataModel; using System.Collections.Generic; using Amazon.DynamoDBv2; using UnityEngine.UI; using UnityEngine; using System.Collections; using Amazon.DynamoDBv2; using UnityEngine.UI; using Amazon;  namespace AWSSDK.Examples { public class HighLevel3 : DynamoDbBaseExample {   private IAmazonDynamoDB _client;  private DynamoDBContext _context;   public Text resultText;  public Button back;  public Button createOperation;  public Button updateOperation;  public Button deleteOperation;  public string S_tablefieldset;  string bookID;  int bookID1 = 9;  public string Email;   private DynamoDBContext Context  {  get  {  if (_context == null)  _context = new DynamoDBContext(_client);   return _context;  }  }   void Awake()  {    back.onClick.AddListener(BackListener);  createOperation.onClick.AddListener(PerformCreateOperation);  _client = Client;  S_tablefieldset = "Orders";  HighLevelTableExample.GetDynamoDbOperationConfig(S_tablefieldset);   }   void Start()  {  bookID = SystemInfo.deviceUniqueIdentifier;  System.Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER", "Orders");  PerformCreateOperation();  }    public static DynamoDBOperationConfig GetDynamoDbOperationConfig(string dynamoDbTable)  {  Debug.Log("The Table name is "   dynamoDbTable);  var tableName = System.Environment.GetEnvironmentVariable("MONO_REFLECTION_SERIALIZER");  Debug.Log("The Table name is"   tableName);  DynamoDBOperationConfig config = new DynamoDBOperationConfig()  {  // OverrideTableName =   OverrideTableName = tableName  };   return config;  }   public void PerformCreateOperation()  {  Debug.Log(" I am in Perform Create Operation is working fine and good");  Book12 myBook = new Book12  {  OrderID = bookID,  OrderItem = 50,    };   // Save the book.  var tableName = System.Environment.GetEnvironmentVariable("TABLE_NAME");  Context.SaveAsync(myBook, new DynamoDBOperationConfig {   OverrideTableName = tableName });    } }       

публичный учебник12 {

 [DynamoDBHashKey] // Hash key.  public string OrderID { get; set; }  [DynamoDBProperty]  public string UserName { get; set; }  [DynamoDBProperty]    }  

}

При выполнении вышеизложенного я получил ошибку в

 error CS1503: Argument 2: cannot convert from   

-Амазонка.DynamoDBv2.Модель данных.DynamoDBOperationConfig’ для Амазонка.DynamoDBv2.AmazonDynamoDBCallback’

Как устранить ошибку.
