Hi @g h ,

Here is the sample code to get files' absolute url in library for your reference:

   using (ClientContext ctx = new ClientContext("https://zheguo.sharepoint.com/sites/dev/"))  
    {  

        ctx.Credentials = new SharePointOnlineCredentials(account, secret);  
        ctx.Load(ctx.Web);  
        ctx.ExecuteQuery();  

        List targetList = ctx.Web.Lists.GetByTitle("Documents");  

        ListItemCollection ItemCol = targetList.GetItems(CamlQuery.CreateAllItemsQuery());  
        ctx.Load(ItemCol);  
        ctx.ExecuteQuery();  
            foreach (Microsoft.SharePoint.Client.ListItem item in ItemCol)  
            {  
                if (item.FileSystemObjectType == FileSystemObjectType.File)  
                {  
                    Console.WriteLine(new Uri(ctx.Url).GetLeftPart(UriPartial.Authority) + item["FileRef"]);  
                }  

            }  
    }

hi, you need to load list.RootFolder (and list.RootFolder.Folders if you want to get files from all folders), then iterate through folder.Files and for each file you will get file.ServerRelativeUrl. Example of the script which uses CSOM for downloading all files in doclib can be found here: Download all files from a document library using client object model. Before to download files it gets downloadable url of each file - this is what you need.
