步骤 10：使用 .NET 删除 Movies 表

在 Microsoft .NET 和 DynamoDB 教程的本步骤中，您将在 Amazon DynamoDB 中删除一个 Movies 表。

DynamoDB_intro 中的 Main 函数将等待 DeletingTable_async，DeletingTable_async 在 10_DeletingTable.cs 文件中实现。

        operationFailed = true;
        return ( false );

      Console.WriteLine( "     -- Successfully deleted the table!" );
      operationSucceeded = true;
      pause( );
      return ( true );
    }
  }

DeletingTable_async 等待低级别 DynamoDB 方法 AmazonDynamoDBClient.DeleteTableAsync 删除表。
