or use INSERT INTO
SqlConnection and SqlCommand with a SqlCommandText.

System.Data.SqlClient.SqlConnection sqlConnection1 =
new System.Data.SqlClient.SqlConnection("YOUR CONNECTION STRING");

System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = "INSERT Region (RegionID, RegionDescription) VALUES (5, 'NorthWestern')";
cmd.Connection = sqlConnection1;

sqlConnection1.Open();
cmd.ExecuteNonQuery();
sqlConnection1.Close();
