分页插件通用处理，以asp.net mvc为例

public class PaggerModel
{
public PaggerModel()
{
BarSize = 10;
}

public PaggerModel(int total, int page, int size) : this()
{
TotalCount = total;
CurrentPageIndex = page;
PageSize = size;
}

public PaggerModel(int total, int page, int size, string action, string controller) : this(total, page, size)
{
ActionName = action;
ControllerName = controller;
}

public string ActionName { get; set; }
public int BarSize { get; set; }
public string ControllerName { get; set; }

/// <summary>
/// 当前页码
/// </summary>
public int CurrentPageIndex
{
get
{
return currentPageIndex;
}
set
{
currentPageIndex = (value < 1 ? 1 : value);
}
}

/// <summary>
/// 最后一页页码
/// </summary>
public int LastPageIndex
{
get
{
if (PageSize == 0)
{
return (int)Math.Ceiling((double)TotalCount / 10);
}
return (int)Math.Ceiling((double)TotalCount / PageSize) == 0 ? 1 : (int)Math.Ceiling((double)TotalCount / PageSize);
}
}

/// <summary>
/// 单个页面显示条目
/// </summary>
public int PageSize
{
get
{
return pageSize;
}
set
{
pageSize = (value < 1 ? 1 : value);
}
}

/// <summary>
/// 总条目
/// </summary>
public int TotalCount { get; set; }
private int currentPageIndex { get; set; }
private int pageSize { get; set; }
}
