Obrigado pela atenção Carlos, segue o código
public partial class Form1 : Form
{
private OracleConnection conexao;
private OracleDataAdapter da;
private DataTable tabela;
private OracleConnectionStringBuilder sb;
public Form1()
{
InitializeComponent();
sb = new OracleConnectionStringBuilder();
sb.DataSource = "ORADESENV";
sb.UserID = "DESENV";
sb.Password = "DESENV";
conexao = new OracleConnection(sb.ConnectionString);
da = new OracleDataAdapter("", conexao);
tabela = new DataTable();
}
private void btnExecutar_Click(object sender, EventArgs e)
{
da.SelectCommand.CommandText = txtSelect.Text;
da.Fill(tabela);
dtgDados.DataSource = tabela;
