Incorrect null state in the array

[drOpen]

If you save null element in the string array the return value is String.Empty instead of null
// Sample
var test = new string[] { "1",null, "2" };
var a = new DDValue(test);
var result = a.GetValue();
/* result contains
{string[3]}
[0]: "1"
[1]: ""
[2]: "2"
*/
