Microsoft.Office.DocumentManagement.DocumentSets namespace.

Below is the full code:

public bool IsDocumentSetItem(SPListItem itemToCheck)
{
bool documentSetItem = false;

if (itemToCheck.File != null)
{

DocumentSet documentSet = DocumentSet.GetDocumentSet(itemToCheck.File.ParentFolder);

if (null != documentSet)
{
documentSetItem = true;
}
}
return documentSetItem;
}

using (SPSite site = new SPSite("http://SiteURL"))
{
using (SPWeb web = site.OpenWeb())
{
web.AllowUnsafeUpdates = true;

SPFolder folder = web.Folders[site.URL + "/Shared Documents/"];

byte[] content = null;

using (FileStream filestream = new FileStream(@"C:\MyDocument.docx",System.IO.FileMode.Open))
{
content = new byte[(int) filestream.Length];

filestream.Read(content, 0, (int) filestream.Length);

filestream.Close();
}

SPFile file = folder.Files.Add("MyDocument.docx", content, true);

}
}

Add an attachment to List item using SharePoint object model

In this post we will discuss about how to add an attachment using SharePoint 2010 object model.

You can also check my previous posts on Get 14 hive file path by using SharePoint 2010 object model [Read here], Get URL value SharePoint hyperlink field [Check here] and How to get Absolute URL of List using SharePoint object model? [Solution here].

string listItemID = "ID of the list item";

using (SPSite site = new SPSite("http://Site URL"))
{
using (SPWeb web = site.OpenWeb())
{
SPList list = web.Lists["MyCustomList"];
SPListItem newItem = list.GetItemById(listItemID);

byte[] contents = null;

if (fileUpload1.PostedFile != null && fileUpload1.HasFile)
{

using (Stream fileStream = fileUpload1.PostedFile.InputStream)
{
contents = new byte[fileStream.Length];
fileStream.Read(contents, 0, (int) fileStream.Length);
fileStream.Close();
}

SPAttachmentCollection attachments = newItem.Attachments;
string fileName = Path.GetFileName(fileUpload1.PostedFile.FileName);
attachments.Add(fileName, contents);
newItem ["AttachmentName"] = fileName;
newItem.Update();

}
}
}

Here fileUpload1 is the file uploaded control. And AttachmentName is the column name in the list.

Create list programmatically using SharePoint object model

In this post we will discuss about how to create a SharePoint list using object model.

You can also check my previous posts on How to Create List and Add Item to that List using SharePoint 2010 client object model? [Solution here], RunWithElevatedPrivileges in SharePoint 2010 [Read here] and Different ways to check logs in SharePoint [Check here].

Below is the code to create list programmatically using SharePoint object model.

using (SPSite site = new SPSite("http://Site URL"))
{
using (SPWeb web = site.OpenWeb())
{
SPList list = null;
string listName = "MyCustomList";

// Check whether the list already exists
try
{
list = web.Lists[listName];
}
catch (Exception ex)
{
}

if (list == null)
{
Guid listId = web.Lists.Add(listName, "Our Custom List", SPListTemplateType.GenericList);
list = web.Lists[listId];
list.OnQuickLaunch = true;
list.Update();
}
}
}

The above code will create a generic list without any extra field. And it will show in Quick Launch.

You can also add custom columns like below:

list.Fields.Add("FirstName", SPFieldType.Text, true);
list.Update();

{
string newGroup = "MyGroup";

web.SiteGroups.Add(newGroup, web.CurrentUser, web.CurrentUser,"This is our new group");

SPGroup group = web.SiteGroups[newGroup];

SPRoleAssignment roles = new SPRoleAssignment(group);

SPRoleDefinition permission = web.RoleDefinitions["Full Control"]; //Here the group will have Full Control permission level.

roles.RoleDefinitionBindings.Add(permission);

web.RoleAssignments.Add(roles);

// Add users to this group
SPUser newUser = web.AllUsers[@"Administratoe\Fewlines4Biju"];

group.AddUser(newUser);
}

The above code will create a group and add a new user to the group.

Which SharePoint 2010 objects should not be disposed

In this post we will discuss about what are the SharePoint objects which should not be disposed explicitly.

You can also check my previous posts on Detecting Memory Leaks in SharePoint 2010, Disposing SharePoint Objects and Client Object Model SharePoint 2010.

Below are some objects which should not disposed:

SPSite site = SPContext.Current.Site;

SPWeb rootWeb = site.RootWeb;

SPWeb web = SPContext.Web;

SPWeb web = SPContext.Current.Web;

SPSite site = SPContext.Site;

SPSite site = SPContext.Current.Site;

Next we should not dispose objects used in a feature receiver like:

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
SPWeb web = properties.Feature.Parent as SPWeb;
}

The below objects should not be disposed.

SPWebEventProperties.Web

SPListEventProperties.Web

SPListEventProperties.List.Web

SPItemEventProperties.ListItem.Web

- Those objects used with personal pages:

The Microsoft.SharePoint.Portal.WebControls.IPersonalPage interface has two properties that return SPSite and SPWeb objects, respectively: IPersonalPage.PersonalSite and IPersonalPage.PersonalWeb.
