Answer 1

string[] filefile = dr["Path_XBRL"].ToString().Split('\\', '-');  

if you check this statement, you will see that the array contains less than 11 elements. If you want to check you may do the following;

if (filefile.Length >11 && string.IsNullOrEmpty(filefile[11]))
{ 
    string yes = "oke";
}
