在 WCF 中使用分页

Posted 2023-05-07

【中文标题】在 WCF 中使用分页

【英文标题】：Paging using in WCF

【发布时间】：2015-11-19 03:05:45

【问题描述】：

首先在分页控件中创建存储过程。再次在分页控件中的存储过程上调用 WCF。最后在使用分页控件的 WPF 应用程序中启用 WCF 服务。

【参考方案1】：

分页控件用于 WCF 应用程序中，包含在存储过程中。此应用程序可以成功执行。我有更多时间测试。

在此处输入代码：服务名称：IEmployeeServices.cs

// 注意：您可以使用“重构”菜单上的“重命名”命令将代码和配置文件中的接口名称“IService1”一起更改。 [服务合同] 公共接口 IEmployeeService #region 属性 [运营合同] 字符串 AddEmployeeDetails(Employee Employee);

    [OperationContract]
    List<Employee> GetEmployeeDetails(int PageNumber,int PageSize,string SortColumn,string SortOrder);

    [OperationContract]
    string UpdateEmployeeDetails(Employee Employee);
    #endregion

enter code here:EmployeeServices.svc

命名空间 EmployeeServiceApps // 注意：您可以使用“重构”菜单上的“重命名”命令将代码、svc 和配置文件中的类名“Service1”一起更改。 公共类 EmployeeService : IEmployeeService #region 方法 /// /// 添加新的 EmployeeRecord 方法 /// /// /// 公共字符串 AddEmployeeDetails(Employee Employee)
