C # How to bulk import data from a dataset into an Oracle database

Do not write INSERT statements, because there are too many database fields, what is the simple point of the efficient method?

Public void Multiinsertdata (DataSet ds)
{
string connt = "Connection string for Oracle";
String sql = "Select Id,name,... from tablename"; must be consistent with the DS
DataTable dt = ds. Defaults[0];
OracleConnection conn = new OracleConnection (CONNSTR);
OracleCommand cmd = new OracleCommand (SQL, conn);
Conn. Open ();
OracleDataAdapter da = new OracleDataAdapter (sqlcmd);
Oraclecommandbuilder cb = new Oraclecommandbuilder (Sqlda);
da. Update (DT);
Conn. Close ();
sqlconn. Dispose ();
}
Use this batch to import, fast, and convenient
