具体方法: 1 ImportRow方法:public void ImportRow( DataRow DataRow); objectTable = sourceTable.clone();//必须先复制表的架构...foreach (DataRow oRow in sourceTable) { objectTable.ImportRow(oRow);//在objectTable中添加一个新行,并将sourceRow
DataSet(); myCommand.Fill(newds ,"Table1") ; for(int i=0;i<oldds.Tables[0].Rows.Count;i++) { //在这里不能使用ImportRow...方法将一行导入到news中,因为ImportRow将保留原来DataRow的所有设置(DataRowState状态不变)。...在使用ImportRow后newds内有值,但不能更新到Excel中因为所有导入行的DataRowState!
for (int i = nStartPos; i < nEndPos; i++) { dtTemp.ImportRow...for (int i = nStartPos; i < nEndPos; i++) { dtTemp.ImportRow
DataTable(); newdt=dt.Clone(); DataRow[] dr = dt.Select(condition); for(int i=0;i<dr.Length;i++) { newdt.ImportRow
DataTable dt = ds.Clone(); foreach (DataRow dr in ds.Rows) dt.ImportRow
(int);//重新指定列类型为int型 foreach (DataRow s in dt.Rows) { dtNew.ImportRow
custTable.Rows.Clear(); foreach (DataRow myRow in tmpTable.Rows) custTable.ImportRow(myRow); // Preserve
for (i = startRec; i < endRec; i++) { dtTemp.ImportRow(dtSource.Rows[i]); recNo += 1; } dataGrid1
); for (int i = 0; i < TreeData.Count; i++) { CopyDataTable.ImportRow
如果只需要某个表中的某一行 DataTable dtNew = new DataTable(); dtNew = dt.Copy(); dtNew.Rows.Clear();//清空表数据 dtNew.ImportRow
= dt.Clone(); for (int i = 0; i < drs.Length; i++) { dtNew.ImportRow
foreach (DataRow dr in dt.Rows) { dtNew.ImportRow
