Parse one string to another

Question

string A = "myString";

string B;

Is there a way to initiate B according to the data of A, so that value B changes with A.

B = capture change of A?

Edit: My initial post was not complete and misleading, I found the answer now. Still my question is a duplicate of observer pattern

Based on what you've provided, substring() would do what you're after. Are you thinking of something a bit more complex? — Adrian Wragg, Jul 30 '13 at 12:43
First two elements = first two characters, or first of two elements as in split by uppercase characters — Tony Hopkinson, Jul 30 '13 at 12:44

Try this

B = A.Substring(0,2);

It initates B with substring of A from index 0 and lenght of 2

You can try the following example

string A = "myString";
string B;

if (A.StartsWith("my"))
{
    B = A.Substring(0, 2);//first two elements of A
}
