Read individual characters from a string
Treat the string as an array
string MyString = "abcd";
char MyChar = MyString[2];
Get Characters Between Markers Within String
string sTemp = responseStr;
string StartAfterChars;
string EndBeforeChars;
int Start;
int Length;
string FoundString;
StartAfterChars = "<requestID>";
EndBeforeChars = "</requestID>";
Start = sTemp.IndexOf(StartAfterChars) + StartAfterChars.Length;
Length = sTemp.IndexOf(EndBeforeChars) - Start;
if ((Start > 0) && (Length > 0))
FoundString = sTemp.Substring(Start, Length);
else
FoundString = "";
