Linq to class objects

This example shows how to use the array of class object and its variables on run time using "LINQ".

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
public class LinqClass
{
    public string Name;
    public string contact;
    public string city;

}

using System.Xml;
using System.Xml.Linq;
using System.Linq;
using System.Data;

var sp = new[] {
          new LinqClass { Name="Murugesan",
                          contact="9769104815",
                          city="Chennai"
                        },
                        new LinqClass { Name="Pandian",
                                        city="Madurai",
                                        contact="9786466642"
                                      }
          };
        foreach (var n in sp)
        { 
            Response.Write(n.Name.ToString());
        }

C# Writing XML strings on runtime

This is an example for creating the XML string from the dynamic data.

StringWriter sw = new StringWriter();
XmlTextWriter txtWriter = new XmlTextWriter(sw);
txtWriter.Formatting = Formatting.Indented;
//txtWriter.WriteStartDocument();
txtWriter.WriteStartElement("Employee");
DataSet myDataSet = new DataSet();
myDataSet.ReadXml("C:\\ContactXML\\Contacts.xml");
foreach (DataRow row in myDataSet.Tables[0].Rows)
{
txtWriter.WriteElementString("Name", row[0].ToString());

}
txtWriter.WriteEndElement();

//txtWriter.WriteEndDocument();
sw.Close();
string s1 = sw.ToString().TrimStart('{');
string s2 = s1.TrimEnd('}');

SharePoint-Active Directory Synchronize

Last week,I prepared the small SharePoint utility to retrieving the Active Directory users and synchronize with SharePoint List.

public string LDAPUsers()
        {
            string listD = "";
            string strResult = "";
            string strRes = "";
            DirectoryEntry entry = new DirectoryEntry("LDAP://domainName", "userid", "pAsSwrd");
            DirectorySearcher mySearcher = new DirectorySearcher(entry);
            mySearcher.Filter = "((objectCategory=Person))";

            foreach (SearchResult resEnt in mySearcher.FindAll())
            {
                listD = listD + resEnt.GetDirectoryEntry().Name + ",";


            }
            string[] test = listD.Split('=');
            for (int i = 0; i < test.Length; i++)
            {
                strResult = strResult + test[i].ToString();
            }

            string[] test1 = strResult.Split(',');
            for (int j = 0; j < test1.Length; j++)
            {
                strRes = strRes + test1[j] + ",";
            }
            return strRes.Replace("CN", ""); ;
        }

Below code pushing the string array values in to SharePoint List.

SPSite site = new SPSite("http://moss:4100");
        SPWeb web = site.OpenWeb();
        SPList list = web.Lists["LDAP User"];
        string[] names = LDAPUsers().Split(',');
        for (int j = 0; j < names.Length; j++)
        {
            SPListItem item = list.Items.Add();
            web.AllowUnsafeUpdates = true;
            item["Title"] = names[j].ToString();
            web.AllowUnsafeUpdates = true;
            item.Update();
            web.AllowUnsafeUpdates = false;
        }
