Try to create an OracleString variable that will be a variable holding one element at a time from an array. Let's say this variable will be called oraStringVar.
Assign a value to it by:
oraStringVar = someListVar[index].Value;
Then you may extract what you need by executing:
string container = oraStringVar.Value
Note doubled use of Value. The same works for extracting clob to a string.
