ArrayList in a Web Service

[cleverum]

i created a web service with an ArrayList
public class Quote
{
public System.Collections.ArrayList Notes;

public Quote()
{
//
// TODO: Add constructor logic here
//
}
}

but when i try to assign my ArrayList m_Notes to objQuote.Notes it tells me..
Cannot implicitly convert type 'System.Collections.ArrayList' to 'object[]'

CommitQuote.CommitQuote objCQ = new CommitQuote.CommitQuote();
CommitQuote.Quote objQuote = new CommitQuote.Quote();

objQuote.Notes = m_Notes;


i checked the wsdl and saw that "Notes" is type ArrayOfAnyType is this right or do i need ArrayList. if i do need the type ArrayList, do i need to change my declaration public System.Collections.ArrayList Notes;

<s:element minOccurs="0" maxOccurs="1" name="Notes" type="tns:ArrayOfAnyType" />
