如何使用csom删除sharepoint中的多个文件

using Microsoft.SharePoint.Client;
using System;

namespace SharePointCSOM
{
    class Program
    {
        static void Main(string[] args)
        {
            string siteUrl = "https://your-sharepoint-site-url";
            ClientContext clientContext = new ClientContext(siteUrl);

            string username = "your-username";
            string password = "your-password";
            clientContext.Credentials = new SharePointOnlineCredentials(username, password);

            List list = clientContext.Web.Lists.GetByTitle("Your-List-Name");
            CamlQuery query = new CamlQuery();
            query.ViewXml = "<View><Query><Where><Eq><FieldRef Name='FileLeafRef'/><Value Type='Text'>file1.txt</Value></Eq></Where></Query></View>";
            ListItemCollection items = list.GetItems(query);
            clientContext.Load(items);
            clientContext.ExecuteQuery();

            foreach (ListItem item in items)
            {
                item.DeleteObject();
            }
            clientContext.ExecuteQuery();

            Console.WriteLine("Files deleted successfully.");
        }
    }
}
