C# DataTable分页处理实例代码

publicDataTable GetPagedTable(DataTable dt,intPageIndex,intPageSize)//PageIndex表示第几页，PageSize表示每页的记录数

  {

   if(PageIndex == 0)

    returndt;//0页代表每页数据，直接返回

   DataTable newdt = dt.Copy();

   newdt.Clear();//copy dt的框架

   introwbegin = (PageIndex - 1) * PageSize;

   introwend = PageIndex * PageSize;

   if(rowbegin >= dt.Rows.Count)

    returnnewdt;//源数据记录数小于等于要显示的记录，直接返回dt

   if(rowend > dt.Rows.Count)

    rowend = dt.Rows.Count;

   for(inti = rowbegin; i <= rowend - 1; i++)

   {

    DataRow newdr = newdt.NewRow();

    DataRow dr = dt.Rows[i];

    foreach(DataColumn columnindt.Columns)

    {

     newdr[column.ColumnName] = dr[column.ColumnName];

    }

    newdt.Rows.Add(newdr);

   }

   returnnewdt;

  }
