public DataTable GetPagedTable(DataTable dt, int PageIndex, int PageSize)//PageIndex表示第几页，PageSize表示每页的记录数

{

if (PageIndex == 0)

return dt;//0页代表每页数据，直接返回

DataTable newdt = dt.Copy();

newdt.Clear();//copy dt的框架

int rowbegin = (PageIndex - 1) * PageSize;

int rowend = PageIndex * PageSize;

if (rowbegin >= dt.Rows.Count)

return newdt;//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 (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;

}

 

//第二种方式

public DataRow[] GetTableRows(DataTable dtAllEas, int PageIndex,int PageSize)

{

　　var rows = dtAllEas.Rows.Cast<DataRow>();

　　var curRows = rows.Skip(PageIndex).Take(PageSize).ToArray();
