To Create DataTable From DataRow Collection

I usually accomplish this with a datareader though:

Dim dt As New DataTable
dt.Columns.Add(New DataColumn("mHostCode", GetType(String)))
dt.Columns.Add(New DataColumn("mTotalFreq", GetType(Integer)))

...do your sql connection and command decleration...

dr = SqlCommand1.ExecuteReader(CommandBehavior.CloseConnection)
Dim datar As DataRow
While dr.Read
  datar = dt.NewRow
  datar(0) = dr(0)
  datar(1) = dr(1)
  dt.Rows.Add(datar)
End While
dr.Close

Hello Balaji,

In following example, I am creating DataTable from DataRow.

----------------------------------------------------------------------------------------------------------------

DataTable dt = new DataTable();
DataView dv;
DataRow dr;
      
                dt.Columns.Add( new DataColumn("Column0",Type.GetType("System.String") ) );
      dt.Columns.Add( new DataColumn("Column1",Type.GetType("System.String") ) );
                        
      dr = dt.NewRow();                                                  //Create 1st Row
      dr[0] = "row1:Column0";
      dr[1] = "row1:Column1";
      
      dt.Rows.Add(dr);                                                   // Add 1st row to table
               
                    dr = dt.NewRow();                                                 //Create 2nd Row
      dr[0] = "row2:Column0";
      dr[1] = "row2:Column1";
      dt.Rows.Add(dr);                                                   // Add 2nd row to table

      dv = new DataView( dt );

----------------------------------------------------------------------------------------------------------------

If the rows already belong to a datatable, if you're getting them from a DataTable.Select for example, you need to use

  myDataTable.ImportRow(myDataRow)

Mine and AerosSaga's code does exactly what user is asking for. But the points should go to AerosSaga as he showed 2 correct alternative method before me.
