How to find a substring in a String.

Hi All,

Is there a routine to find a substring in a String?
I would like to have a routine that can be used in this way:

String* S;
String* SubStr = ".";
do
{ S = Console::ReadLine() }
while(Pos(SubStr, S) == 0);
//Pos returns the index of the first letter of the substring inside the string. And if it doesn't find the substring, then it returns 0.

I was looking for a routine that works with .net and not the old C++.

I found what I was looking for though:

String* S;
String* SubStr = ".";
do
{ S = Console::ReadLine() }
while(S->IndexOf(SubStr) < 0);

Do you really sure what this line of code does?
It seems you are assigning the random address to your pointer-to-string variable...
