Hi @nellie ,

According to my research and testing, you can use the following code to create/update/delete list items in batch using CSOM :

            var ctx = GetonlineContext();  
            Web spWeb = ctx.Web;  
            spWeb = ctx.Web;  
            ctx.Load(spWeb);  
            List spList = spWeb.Lists.GetByTitle("<ListName>");  
  
            //Create SharePoint List Items In Batch  
            for (var i = 1; i < 20; i++)  
            {  
                try  
                {  
                    ListItemCreationInformation spItemInfo = new ListItemCreationInformation();  
                    ListItem spItem = spList.AddItem(spItemInfo);  
                    spItem["Title"] = "MyNewItem-" + i.ToString();  
                    spItem.Update();  
                }  
                catch (Exception ex) {   
               Console.WriteLine("Error:- " + ex.ToString());  
                }  
            }  
            ctx.ExecuteQuery();  
  
  
            //update SharePoint List Items In Batch  
            /*  
            for (var i = 1; i < 20; i++)  
            {  
                try  
                {  
                    ListItem spItem = spList.GetItemById(i);  
                    spItem["Title"] = "UpdatedItem-"+i.ToString();  
                    spItem.Update();  
                }  
                catch (Exception ex)  
                {  
                    Console.WriteLine("Error:- " + ex.ToString());  
                }  
            }  
            ctx.ExecuteQuery();  
            */  
  
  
            //delete SharePoint List Items In Batch  
            /*  
            for (var i = 1; i < 10; i++)  
            {  
                try  
                {  
                    ListItem spItem = spList.GetItemById(i);  
                    spItem.DeleteObject();  
                }  
                catch (Exception ex)  
                {  
                    Console.WriteLine("Error:- " + ex.ToString());  
                }  
            }  
            ctx.ExecuteQuery();  
            */
