Read From Excel & Import to Sharepoint List - Using Web Services

Another code snippet using SharePoint-Web Services. Requirement is: End-User wants to read data from Microsoft Excel (it will be placed at c:\contracts.xls) and append to SharePoint List (List Name: Contracts) on-demand from his desktop.

So the idea is: Lets build a console application, Add a web service reference to SharePoint List web service http://<Site>/_vti_bin/Lists.asmx and give it to the end user. Let him run the console application from his desktop on-demand.

using System;
using System.Collections;
using System.Data;
using System.Xml;
using System.IO;
using System.Data.OleDb;
using System.Data.Common;

namespace ReadFromExcelImportToSharePoint
    class Program
        static void Main(string[] args)
            DateTime dt;
            string dt1;
   //initialize Web Service Reference
   Site1.Lists.Lists list = new ListWebservice.Site1.Lists.Lists();
   list.Credentials = System.Net.CredentialCache.DefaultCredentials;

            XmlNode contacts = list.GetList("Contracts");  

   XmlDocument doc = new XmlDocument();

   string listName = contacts.Attributes["ID"].Value;

            string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\contracts.xls;Extended Properties=""Excel 8.0;HDR=YES;""";
            DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.OleDb");
            using (DbConnection connection = factory.CreateConnection())
                connection.ConnectionString = connectionString;
                using (DbCommand command = connection.CreateCommand())
                    command.CommandText = "SELECT * FROM [Sheet1$]";
                    using (DbDataReader dr = command.ExecuteReader())
                        int i = 0;
                        while (dr.Read())
                            lblRecordNo.Text = i.ToString();

                            XmlElement elBatch = doc.CreateElement("Batch");
                            elBatch.SetAttribute("OnError", "Continue");
                            elBatch.SetAttribute("ListVersion", "1");

                            XmlElement el1 = doc.CreateElement("Method");

                            el1.SetAttribute("Cmd", "New");

                            XmlElement field1 = doc.CreateElement("Field");
                            field1.SetAttribute("Name", "ID");
                            field1.InnerText = "New";

                            //From Here List Fields starts.
                            XmlElement field2 = doc.CreateElement("Field");

                            field4.SetAttribute("Name", "SAP_x002f_Legacy_x0020_Pricing_x");
                            field4.InnerText = dr["SAP/Legacy Pricing System"].ToString();

                            XmlElement field5 = doc.CreateElement("Field");

                            field8.SetAttribute("Name", "Effective_x0020_Date");
                            dt = Convert.ToDateTime(dr["Effective Date"].ToString()) ;
                            field8.InnerText = dt1;
                            XmlElement field9 = doc.CreateElement("Field");
                            field9.SetAttribute("Name", "SBU");
                            field9.InnerText = dr["SBU"].ToString();

                            XmlElement field10 = doc.CreateElement("Field");

  1. Site1.Lists.Lists list = new ListWebservice.Site1.Lists.Lists();

    can you please explain what this statement is for??

    1. That is to Initiate SharePoint List Web Service! Just right click the Project >> Add Web Reference >> Specify SharePoint List Web service URL >> Give name as: Site1.Lists

  2. How to update the lookup fields and people and group fields.

    1. Lookup fields need to use the format of - number;#LookupValue

      Where the number is the index of the lookup item. So, You got to get the index using GetListItems or some other method first!

  3. I am using Visual studio 2015, I was not able to add Web reference. Did some research on it on some forums and tried several approaches but couldn't possibly find a solution. Let me know if there is an alternate option to replace web reference and code something inline to connect to the sharepoint url.
