C# Sharepoint 读取和更新

安装Microsoft.SharePointOnline.CSOM

1.根据sapno，更新状态

            List<ListItem> listAll = new List<ListItem>();using (ClientContext clientContext = new ClientContext(siteURL)){SecureString secureString = new SecureString();foreach (char c in DecryptAES.Decrypt(password).ToCharArray()) secureString.AppendChar(c);clientContext.Credentials = new SharePointOnlineCredentials(DecryptAES.Decrypt(username), secureString);List vendorList = clientContext.Web.Lists.GetByTitle("Information");CamlQuery camlQuery = new CamlQuery();foreach (DataRow dr in dt.Rows){string sapno = dr[0] == null ? "" : dr[0].ToString().Trim().Replace("\r\n", "");if (!string.IsNullOrEmpty(sapno)){camlQuery.ViewXml = "<View><Query><Where><Eq><FieldRef Name='SAP_x002d_Code'/><Value Type='Text'>" + sapno + "</Value></Eq></Where></Query></View>";ListItemCollection listItems = vendorList.GetItems(camlQuery);clientContext.Load(listItems);clientContext.ExecuteQuery();if (listItems.Count > 0){foreach (ListItem item in listItems){if (item["_x72b6__x6001_"].ToString() == "禁用"){LoggerHelper.Monitor("已被禁用: ID=" + item["ID"] + ",VendorName=" + item["_x4f9b__x5e94__x5546__x4e2d__x65"] + ",SAPCode=" + item["SAP_x002d_Code"]);}else{item["_x72b6__x6001_"] = "禁用";item.Update();clientContext.ExecuteQuery();}}}else{LoggerHelper.Monitor("未查询到：" + sapno);}}}}

2.读取sharepoint list数据（循环，每次读取500行）

        public static List<ListItem> GetData(string siteUrl, string viewTitle){try{List<ListItem> listAll = new List<ListItem>();using (ClientContext clientContext = new ClientContext(siteUrl)){SecureString secureString = new SecureString();foreach (char c in DecryptAES.Decrypt(password).ToCharArray()) secureString.AppendChar(c);clientContext.Credentials = new SharePointOnlineCredentials(DecryptAES.Decrypt(username), secureString);List vendorList = clientContext.Web.Lists.GetByTitle(viewTitle);ListItemCollectionPosition itemPosition = null;while (true){CamlQuery camlQuery = new CamlQuery();camlQuery.ListItemCollectionPosition = itemPosition;camlQuery.ViewXml = @"<View><RowLimit>500</RowLimit></View>";//camlQuery.ViewXml = "<View Scope=\"RecursiveAll\"></View>";ListItemCollection listItems = vendorList.GetItems(camlQuery);clientContext.Load(listItems);clientContext.ExecuteQuery();itemPosition = listItems.ListItemCollectionPosition;Console.WriteLine(itemPosition);var list = listItems.ToList();listAll.AddRange(list);if (itemPosition == null)break;Console.WriteLine(itemPosition.PagingInfo);}}return listAll;}catch (Exception ex){throw ex;}}

3.获取最近更新过的数据

        public static List<ListItem> GetIncData(string siteUrl, string viewTitle){try{string offset = ConfigurationManager.AppSettings["offset"];List<ListItem> listAll = new List<ListItem>();using (ClientContext clientContext = new ClientContext(siteUrl)){SecureString secureString = new SecureString();foreach (char c in DecryptAES.Decrypt(password).ToCharArray()) secureString.AppendChar(c);clientContext.Credentials = new SharePointOnlineCredentials(DecryptAES.Decrypt(username), secureString);List vendorList = clientContext.Web.Lists.GetByTitle(viewTitle);ListItemCollectionPosition itemPosition = null;CamlQuery camlQuery = new CamlQuery();camlQuery.ListItemCollectionPosition = itemPosition;//camlQuery.ViewXml = "<View><Query><Where>< Geq >< FieldRef Name =\"Modified\" />< Value Type = \"DateTime\" ><Today  OffsetDays = \"-1 \"></ Today ></ Value ></ Geq ></ Where ></ Query >< RowLimit>500</RowLimit></View>";camlQuery.ViewXml = "<View><Query><Where><Geq><FieldRef Name='Modified'/><Value Type='DateTime'><Today OffsetDays='" + offset + "'/></Value></Geq></Where></Query></View>";//camlQuery.ViewXml = "<View Scope=\"RecursiveAll\"></View>";ListItemCollection listItems = vendorList.GetItems(camlQuery);clientContext.Load(listItems);clientContext.ExecuteQuery();//itemPosition = listItems.ListItemCollectionPosition;//Console.WriteLine(itemPosition);var list = listItems.ToList();listAll.AddRange(list);//if (itemPosition == null)//    break;//Console.WriteLine(itemPosition.PagingInfo);}return listAll;}catch (Exception ex){throw ex;}}
