There are two questions actually.

Is it ok to use goto operators, that leads outside try/catch block
and what consequences may it lead to?

How can I make this code better?


    start:
    try
    {
        oleDbDataAdapter1.Fill(dataSetRTTCExcel3.main as DataTable);
    }
    catch (Exception ex) {
        DialogResult res = MessageBox.Show("Can't load data:\n" + ex.Message, "Error",
            MessageBoxButtons.RetryCancel, MessageBoxIcon.Error);
        if (res == DialogResult.Retry)
        {
            goto start;
        }
    }
