Adding Web Reference changes IList to Array[]

When i add a web reference to my client app, the web reference classes properties are changed from ILists to arrays. So snippet below. Would there be a reason for this? I just like working with ILists more since they are so dynamic. Could i change this on n client side to ILists?

Server side

    [DataMember]
    public IList<Lookup> Looku开发者_开发问答p { get; set; }

Client side

    [System.Runtime.Serialization.DataMemberAttribute()]
    public FANDI.Data.BusinessObjects.Lookup[] Lookup
    {
        get
        {
            return this.LookupField;
        }
        set
        {
            this.LookupField = value;
        }
    }

A web service reference don't support Lists, only arrays.

If you use Service Reference instead of Web Reference you can specify the collection type to use.

public FANDI.Data.BusinessObjects.Lookup[] Lookup

That line of code suggests that it is an array of lookup objects (Lookup[]).

Can you not change this to

public IList<FANDI.Data.BusinessObjects.Lookup> Lookup
