I have a problem trying to iterate through the Attachment
Collection.
Even when the count of Attachments is greater than 0 I
still get an error message as follows.

Error: Index (zero based) must be greater than or equal
to zero and less than the size of the argument list.
I have included the code below.

int i = 1;                   
foreach (Outlook.Attachment att in oMail.Attachments)
{                        
    SqlCommand cmAttachmentCommand = new SqlCommand
("SP_Add_Outlook_Email_Attachments", sqlConn);
                                  
    cmAttachmentCommand.CommandType =
CommandType.StoredProcedure;
                       
    // Add Parameters to SPROC
                           
    cmAttachmentCommand.Parameters.Add(new
SqlParameter("@MailAttachmentID", attachmentID));
                           
    cmAttachmentCommand.Parameters.Add(new
SqlParameter("@MailAttachmentNumber", i));
                           
    cmAttachmentCommand.Parameters.Add(new
SqlParameter("@MailAttachmentType", 1));
       
    // ## ERROR OCCURS HERE !!!!!           
    cmAttachmentCommand.Parameters.Add(new
SqlParameter("@BlobField", att));

                           
    // Open the connection and execute the Command
                           
    cmAttachmentCommand.ExecuteNonQuery();
                           
    i++;
}
