The data source is not limited to SQL Server, any data source can be used.
SqlBulkCopy offers a significant performance.






Example:

string sourceConnectionString = "YourSourceConnectionString";

string destinationConnectionString = "YourDestinationConnectionString";

using (SqlConnection sourceConnection =

       new SqlConnection(sourceConnectionString))

            {

                sourceConnection.Open();

                SqlCommand commandSourceData = new SqlCommand(

                    "SELECT * FROM source_table;", sourceConnection);

                SqlDataReader reader = commandSourceData.ExecuteReader();

                using (SqlConnection destinationConnection =

                           new SqlConnection(destinationConnectionString))

                {

                    destinationConnection.Open();

                    using (SqlBulkCopy bulkCopy =

                               new SqlBulkCopy(destinationConnection))

                    {

                        bulkCopy.DestinationTableName = "dbo.destination_table";

                        try

                        {

                            bulkCopy.WriteToServer(reader);

                        }

                        catch (Exception ex)

                        {

                            MessageBox.Show(ex.Message);

                        }

                        finally

                        {
