  <p>Object: (</p>
  
  <pre><code>   class CashCaseDTO { string CaseId {get;set;} double CaseTotalAmount {get;set; }
  </code></pre>
  
  <p>To:</p>
  
  <pre><code>public class CashCase
  {
      public string Id { get; set; }
  
  }
  
  public class CashCaseDifference
  {
      public decimal Amount { get; set; }
  }
  </code></pre>
