To fetch the User name in Console application is as follows


using Microsoft.SharePoint;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{

SPSite rootSite = new SPSite("http://jaganinfo-pc:1234/");
SPWeb rootWeb= rootSite.RootWeb;
SPUserCollection userList = rootWeb.AllUsers;
foreach (SPUser objUser in userList)
{
Console.WriteLine(objUser.Name);
}
Console.Read();
}
}
}
********************************************************************

Q) Write a Query SharePoint List by using LINQ


// Get DataContext from page context
DataContext data = new DataContext(SPContext.GetContext(this.Context).Web.Url);

// Get the SharePoint list
EntityList Customers = data.GetList("Customers");

// Query for customers from India
var indiaCustomers = from customer in Customers
where customer.City == "India"
select customer;

foreach (var indiaCust in indiaCustomers)
{
Console.Writeline("id = {0}, City = {1}", indiaCust.CustomerId, londonCust.City);
}
********************************************************************

Q) Write a program to Get All Alerts in the Site Collection

public void GetAlerts(Button btn)
{
SPSite rootSite = SPContext.Current.Site;
SPWeb rootWeb = rootSite.OpenWeb();

//Using RunWithElevatedPrivileges

SPSecurity.RunWithElevatedPrivileges(delegate()
{
// Get references to the site collection and site for the current context.
// The using statement makes sures these references are disposed properly.

SPList alertList = rootWeb.Lists[LIBName.Trim()];
DeleteAllExistingItems(alertList, btn); // Delete existing items

using (SPSite siteCollection = new SPSite(rootSite.ID))
{
foreach (SPWeb curretWeb in siteCollection.AllWebs)

//Get alerts for each web
{
using (SPWeb web = siteCollection.OpenWeb(curretWeb.ID))
{
web.AllowUnsafeUpdates = true;

try
{
SPAlertCollection allAlerts = web.Alerts;

foreach (SPAlert AlertItem in allAlerts)
{
AddAlertToTable(alertList, AlertItem);
}
}
catch (Exception ex)
{
Console.WriteLine("Delete failed: " + ex.Message);
throw;
}

web.AllowUnsafeUpdates = false;
}
}
}

});
}

Q) Programmatically Upload Documents in a Document Library

public void DocumnetsUpload(SPWeb site)
{
if (FileUploadControl.HasFile)
{
SPFolder folder = site.GetFolder("Document_Library_Name");

SPFileCollection files = folder.Files;

//path of the file to upload
Stream fStream = FileUpload1.PostedFile.InputStream;

byte[] contents = new byte[fStream.Length];

fstream.position = 0;

fStream.Read(contents, 0, (int)fStream.Length);

fStream.Close();

string Filename = FileUpload1.FileName;

string URL = SPContext.Current.Site.Url + "/Document_Library_Name/" + Filename;

SPFile currentFile = files.Add(URL, contents);
}
}

Q) Write a program to Delete all Items in a list

Note: Deleting all items in list will send all the items to recycle bin. To avoid fill-up recycle bin, we can just turn the recycle bin off while deleting the items.

public void DeleteAllItems(SPList CurrentList)
{
bool IsRecycleBinEnabled = SPContext.Current.Web.Site.WebApplication.RecycleBinEnabled;

if (IsRecycleBinEnabled)
{
//set the use off the recyclebin to false SPContext.Current.Web.site.Webapplication.RecycleBinEnabled = fasle;
}

StringBuilder sbDelete = new StringBuilder();

sbDelete.Append("");

foreach (SPListItem item in CurrentList.Items)
{
sbDelete.Append("");

sbDelete.Append("");

sbDelete.Append("" + Convert.ToString(item.ID) + "");

sbDelete.Append("");

sbDelete.Append("
");
}

sbDelete.Append("");
try
{
SPContext.Current.Site.RootWeb.ProcessBatchData(sbDelete.ToString());
}
catch (Exception ex)
{
Console.WriteLine("Delete failed: " + ex.Message);
throw;
}
if (!IsRecycleBinEnabled)
{
//set the use off the recyclebin to false

//SPContext.Current.Web.site.Webapplication.RecycleBinEnabled = true;
}

Q) SharePoint search using FullTextSqlQuery

//Here SharedServices2 refers to the Shared Service Provider servicing the site in Question

ServerContext context = ServerContext.GetContext("SharedServices2");

FullTextSqlQuery qrySearch = new FullTextSqlQuery(context);

//Specifies the results set containing the main search results from

//the content index matching the search query.

qrySearch.ResultTypes = ResultType.RelevantResults;

//Sremming : expansion of searches to include plural forms and

//other word variations :-)
qrySearch.EnableStemming = true;

qrySearch.TrimDuplicates = false;

qrySearch.QueryText = "SELECT URL, Title, Size, Write, HitHighlightedSummary FROM SCOPE() where \"scope\"='NTFS Archive' And FREETEXT(*,'" + TextBox1.Text.Trim() +

"')";

ResultTableCollection results = qrySearch.Execute();

ResultTable resultTable = results[ResultType.RelevantResults];

// Data Table to Store Search Results

DataTable dtResults = new DataTable();

dtResults.Load(resultTable, LoadOption.OverwriteChanges);
