Usage of Blob type.

Question

Does anyone can help me with usage of Blob type? I'm working with C# with Oracle.DataAccess.Lite.dll, and I need to save an image to the database.
Thanks.

Here is a sample from metalink
    LiteCommand cmd = new LiteCommand(con);
    FileStream file;
    byte[] buffer = new byte[256];
    long lngOffset = 0;
    int chunk;
        con.Open();
        Debug.Print("Connection Open");
        LiteLob imgBlob = new LiteLob(con);
        file = new FileStream("c:\\BlobTest\\Sample.jpg", FileMode.Open);
        Debug.Print("jpg File Opened");
        do {
            chunk = file.Read(buffer, 0, 256);
            imgBlob.SetBytes(lngOffset, buffer, 0, chunk);
            lngOffset += chunk;
        } while (chunk != 0);
        cmd.CommandText = "INSERT INTO TEST_IMAGE VALUES('Sample.jpg', ?)";
        cmd.Parameters.Add(new LiteParameter("image", imgBlob));
        cmd.ExecuteNonQuery();
        cmd.Parameters.Clear();
        con.Commit();
        file.Close();
        Debug.Print("jpg File Closed");
        MessageBox.Show("Blob Successfully Inserted", "Done");
        catch (Exception ex) {
            Debug.Print(ex.Message);
        } finally {
            if (con.Connection.State == ConnectionState.Open) {
                con.Close();
                Debug.Print("Connection Closed");
    }
