Example
// C#
using System;
using Oracle.DataAccess.Types;
class OracleStringSample
{
static void Main()
{
// Initialize OracleString structs
OracleString string1 = new OracleString("AAA");
// Display the string "AAA"
Console.WriteLine("{0} has length of {1}", string1, string1.Length);
// Contatenate characters to string1 until the length is 5
while (string1.Length < 5)
string1 = OracleString.Concat(string1,"a");
// Display the string of "AAAaa"
Console.WriteLine("{0} has length of {1}", string1, string1.Length);
}
