所以我需要创建这个银行服务。除了在提款或存款等交易后尝试使用客户的更新余额外，我拥有一切。例如，客户以 1000 美元开始，客户 1 存入 300 美元。更新后的余额应该是 1300 美元，但是一旦我进行另一笔交易，它就会回到默认的 1000 美元，而不是新的 1300 美元。客户在列表中。

[ServiceContract(SessionMode=SessionMode.Allowed)]

    [OperationContract]
    string GetCustDetails(int act);

    [OperationContract]
    string DepositMoney(int act,double amt);

    [OperationContract]
    string ViewBalance(int act);

您如何使用这项服务？我的意思是说您是如何创建客户的（您可以发布一些代码）。

使用服务时会考虑以下要点

  • 添加服务引用
  • 创建客户端实例
  • 调用实例的 Web 方法
