Question

I have this code:

string Str = "<String><MoreString>";
int Start = Str.LastIndexOf('<') + 1;
int End = Str.IndexOf('>', Start);
string S = Str.Substring(Start, End);

If Str is just "<String>", then it works fine, but if Str is "<String><MoreString>", then it throws an index out of range error. Is it because of the “<“,”>” characters?

Answer 1

Substring doesn’t work like this.

Example :

String myString = "abc";
bool test1 = myString.Substring(2, 1).Equals("c"); // This is true.

The second argument is the number of characters you’re going to select, so you should do :

string S = Str.Substring(Start, End-Start);
