datareader - oracle reader returning System.Data.OracleClient.OracleCommand as value -

-

i'm stumped thing.

i'm using simple following code:

con.connectionstring = @"data source=(description=(address_list=(address=(protocol=tcp)(host=myhost)(port=1521)))(connect_data=(server=dedicated)(service_name=myservice)));user id=myuser;password=mypassword";             con.open();             oraclecommand command = con.createcommand();             command.commandtext = "select srvid mytable used=0 , rownum = 1";             oracledatareader reader = command.executereader();             while (reader.read())             {                 readercheck = reader.getstring(0);             }

for whatever reason, reader.getstring(0) won't work because value it's trying access object of type system.data.oracleclient.oraclecommand.

if use reader.tostring() actualy returns "system.data.oracleclient.oraclecommand" string!

help appreciated!!

i found while searching solution same problem. getstring(0) won't work because you'll illegal cast error, because first element in reader decimal, won't cast directly string. 

  reader.item(1).tostring

or 

  reader.getstring(1)
