Help me covert the Java code to C# code

I want to covert the following code to C# code, but always meet troubles.

Could you help on that? Thanks!

	/**
* Returns an iterator for the DNA sequences in this list.
*
* @return Iterator.
*/
public Iterator<DnaSequence> iterator()
{
return new Iterator<DnaSequence>()
{
int i = 0;
public boolean hasNext()
{
return i < mySequence.length;
}
public DnaSequence next()
{
return mySequence[i++];
}
public void remove()
{
throw new UnsupportedOperationException();
}
};
}
