C# DataTable分頁處理

public DataTable GetPagedTable(DataTable dt, int PageIndex, int PageSize)//PageIndex表示第幾頁，PageSize表示每頁的記錄數

{

if (PageIndex == 0)

return dt;//0頁代表每頁資料，直接傳回

DataTable newdt = dt.Copy();

newdt.Clear();//copy dt的架構

int rowbegin = (PageIndex - 1) * PageSize;

int rowend = PageIndex * PageSize;

if (rowbegin >= dt.Rows.Count)

return newdt;//源資料記錄數小于等于要顯示的記錄，直接傳回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;

//第二種方式

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

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

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