Object Model SPListItem Class


You can use an indexer to return a single item from a list item collection. For example, if the collection is assigned to a variable named collListItems, use collListItems[index] in Microsoft C#, or collListItems(index) in Microsoft Visual Basic, where index is the index number of the item in the collection, or the internal name or display name of a list field. For an indexer based on a name, Microsoft SharePoint Foundation first looks for the field by internal name and then by display name.


To assign values to a field in a list item using an indexer, the values must be represented in a format that is appropriate for each built-in field type. The following table shows how the data types that are used in SharePoint Foundation field types map to Microsoft .NET Framework types.

In my  Last Post , I talked about creating a Form based authentication web application with Active Directory LDAP. After implementing that you have surely noticed that, when you try to sign in after creating a site collection from FBA web application, you get the following sign in page: Surely, it does not look pretty at all. So, you might want to change this default login page. In order to do this, first let us create an empty SharePoint project in Visual Studio 2010. After that, add an application page by right click-selecting “Add New Item” and you will get like the following window in Solution Explorer: Notice that, when you add any application page to your project, Visual Studio automatically creates a Layouts  folder.
