asp.net DataTable Merge

Two structure-like DataTable merging

 
 

  
  

  
DataTable DataTable1 = new DataTable ();
  
  

  
DataTable DataTable2 = new DataTable ();
  
  

  
DataTable newdatatable = Datatable1.clone ();
  
  

  

  
  

  
object[] obj = new Object[newdatatable.columns.count];
  
  

  
for (int i = 0; i < DataTable1.Rows.Count; i++)
  
  

  
{
  
  

  
Datatable1.rows[i]. Itemarray.copyto (obj,0);
  
  

  
NEWDATATABLE.ROWS.ADD (obj);
  
  

  
}
  
  

  
for (int i = 0; i < DataTable2.Rows.Count; i++)
  
  

  
{
  
  

  
Datatable2.rows[i]. Itemarray.copyto (obj,0);
  
  

  
NEWDATATABLE.ROWS.ADD (obj);
  
  

  
}
  
  

  
Or
  
  

  
DataTable DataTable1 = new DataTable ();
  
  

  
DataTable DataTable2 = new DataTable ();
  
  

  

  
  

  
object[] obj = new Object[datatable1. Columns.count];
  
  

  
for (int i = 0; i < DataTable2.Rows.Count; i++)
  
  

  
{
  
  

  
Datatable2.rows[i]. Itemarray.copyto (obj,0);
  
  

  
DATATABLE1.ROWS.ADD (obj);
  
  

  
}
  
  

  
DataTable DataTable1 = new DataTable ();
  
  

  
DataTable DataTable2 = new DataTable ();
  
  

  
DataTable newdatatable = Datatable1.clone ();
  
  

  

  
  

  
object[] obj = new Object[newdatatable.columns.count];
  
  

  
for (int i = 0; i < DataTable1.Rows.Count; i++)
  
  

  
{
  
  

  
Datatable1.rows[i]. Itemarray.copyto (obj,0);
  
  

  
NEWDATATABLE.ROWS.ADD (obj);
  
  

  
}
  
  

  
for (int i = 0; i < DataTable2.Rows.Count; i++)
  
  

  
{
  
  

  
Datatable2.rows[i]. Itemarray.copyto (obj,0);
  
  

  
NEWDATATABLE.ROWS.ADD (obj);
  
  

  
}
  
  

  
Or
  
  

  
DataTable DataTable1 = new DataTable ();
  
  

  
DataTable DataTable2 = new DataTable ();
  
  

  

  
  

  
object[] obj = new Object[datatable1. Columns.count];
  
  

  
for (int i = 0; i < DataTable2.Rows.Count; i++)
  
  

  
{
  
  

  
Datatable2.rows[i]. Itemarray.copyto (obj,0);
  
  

  
DATATABLE1.ROWS.ADD (obj);
