C\#创建分页基类

在Model层（实体层）下创建Base目录，用于存放基类信息。

**1、创建分页接口类**

/// <summary>
    /// 分页接口类
    /// </summary>
    public interface IPaging
    {
        /// <summary>
        /// 是否允许分页
        /// </summary>
        bool AllowPaging { get; set; }
    
        /// <summary>
        /// 排序
        /// </summary>
        string OrderBy { get; set; }
    
        /// <summary>
        /// 当前页码
        /// </summary>
        int PageIndex { get; set; }
    
        /// <summary>
        /// 分页大小
        /// </summary>
        int PageSize { get; set; }
    
        /// <summary>
        /// 当前页总数
        /// </summary>
        int TotalCount { get; set; }
    
        /// <summary>
        /// 总页数
        /// </summary>
        int TotalPage { get; set; }
    }

**2、创建分页基类，并实现IPaging接口**

/// <summary>
    /// 分页基类
    /// </summary>
    public class PagingEntity : IPaging
    {
        //默认页码
        public const int _pageIndex = 1;
    
        //默认页数
        public const int _pageSize = 10;
    
        /// <summary>
        /// 构造函数
        /// </summary>
        public PagingEntity()
        {
            this.PageIndex = _pageIndex;
            this.PageSize = _pageSize;
        }
    
        /// <summary>
        /// 是否允许分页
        /// </summary>
        public bool AllowPaging { get; set; }
    
        /// <summary>
        /// 排序
        /// </summary>
        public string OrderBy { get; set; }
    
        /// <summary>
        /// 当前页码
        /// </summary>
        public int PageIndex { get; set; }
    
        /// <summary>
        /// 分页大小
        /// </summary>
        public int PageSize { get; set; }
    
        /// <summary>
        /// 当前页总数
        /// </summary>
        public int TotalCount { get; set; }
    
        /// <summary>
        /// 总页数
        /// </summary>
        public int TotalPage { get; set; }
    }

**3、创建分页结果类，并继承PagingEntity类**

/// <summary>
    /// 分页结果类
    /// </summary>
    public class ConditionResult<T> : PagingEntity where T : class
    {
        public List<T> ResultList { get; set; }
    }
