以下的分页方法是针对数据量不是非常大的数据进行的，是在内存中进行的分页操作。
/// <summary>
/// DataTable分页
/// </summary>/// <param name="dt">DataTable</param>/// <param name="PageIndex">页索引,注意：从1开始</param>/// <param name="PageSize">每页大小</param>/// <returns>分好页的DataTable数据</returns> 第1页 每页10条public static DataTable GetPagedTable(DataTable dt, int PageIndex, int PageSize)
{ if (PageIndex == 0){return dt;}
DataTable newdt = dt.Copy();
newdt.Clear();
int rowbegin = (PageIndex - 1) * PageSize;
int rowend = PageIndex * PageSize;
if (rowbegin >= dt.Rows.Count)
{ return newdt; }
if (rowend > dt.Rows.Count)
{ rowend = dt.Rows.Count; }
for (int i = rowbegin; i <= rowend - 1; i++)
{
DataRow newdr = newdt.NewRow();
DataRow dr = dt.Rows[i];
foreach (DataColumn column in dt.Columns)
{
newdr[column.ColumnName] = dr[column.ColumnName];
}
newdt.Rows.Add(newdr);
}
return newdt;
}/// <summary>/// 返回分页的页数/// </summary>/// <param name="count">总条数</param>/// <param name="pageye">每页显示多少条</param>/// <returns>如果 结尾为0：则返回1</returns>public static int PageCount(int count, int pageye)
{ int page = 0;
int sesepage = pageye;
if (count % sesepage == 0) { page = count / sesepage; }
else { page = (count / sesepage) + 1; }
if (page == 0) { page += 1; }
return page;
