Hi everyone,

i am new to Asp.net and oracle,

Here i want to fetch the email(BLOB Type) from the table , problem is while i fetch the blob data through datatable, the xml data contains SYSTEM.Byte[]
here sample code
-----------------
Dim Dt As New DataTable

If Dt .Rows.Count > 0 Then
                If (Not Dt .Rows(0).Item(0) Is DBNull.Value) Then

                    blobMail = DirectCast(Dt .Rows(0).Item(0), Byte())
                    
                End If
            End If

here actually datatable object Dt should contain BLOB values like 0101 2001, but its fetch this SYSTEM.Byte[]
