how can i turn this java method to c#

public String generateSP()
String s = "";
Iterator iterator = hmTable.keySet( ).iterator();
String s1 = "";
while(iterator. hasNext())
String s2 = (String)iterato r.next();
s = s.length() != 0 ? s + "," + s2 : s2;
return s;

The var s1 appears never used?
public String generateSP()
String s = null;
foreach (String s2 in hmTable.Keys)
s = (s != null) ? (s + "," + s2) : s2;
return s;

Due to some error, I have to post twice. Sorry if it this reply appears

Thx Truong Hong Thi

another ques.
dose c# has some type like java type Vector (java.util.Vect or)

C# System.Collecti ons.ArrayList provide similar functions, but is is
not thread-safe by default. To have thread-safe array list like
java.util.Vecto r, use ArrayList.Synch ronized method:

ArrayList theVector = ArrayList.Synch ronized(new ArrayList);

Hope that helps,

However, that model of thread-safety is pretty shallow anyway - you
can't safely iterate through a synchronized ArrayList (or Vector in
Java) without locking for the whole loop rather than just each bit of
the loop.

Personally I usually avoid the synchronized wrappers, explicitly
locking the SyncRoot property (or a private lock) if a collection needs
to be shared between threads.
