SharePoint Web Service, why there is no GetListItems() function?

I have added a SharePoint service to my C# Windows Form project. I am able to retrieve available Lists from server. But when I trying to get the data from a List, I am can't find the method GetListItems(). I only saw GetListItemsRequest and GetListItemsRequestBody. All Google results related to GetListItems() but almost none on GetListItemsRequest().

Anything I have missed out? Anyone can help on this? Thanks a lot.

Sorry, my bad. I tried to add service again. And do a search in my solution, I found the GetListItems() function under ListSoapClient. Somehow I can replicate what I did previously that it's not available und开发者_高级运维er ListSoapClient, thus I can identify what I did wrong. Thank you all for your response. Appreciate it.

It is available under the Lists service.
