Property Value

Type: Microsoft.SharePoint.SPFile
An object that represents the file. Returns a null reference (Nothing in Visual Basic) in a document library if the item does not exist. The File property also returns a null reference (Nothing in Visual Basic) if the item is a folder, or if the item is not located in a document library, although it is not recommended that you call this property in these cases.

Examples

The following code example uses the File property to display the file name and check out status of every .xml file in Shared Documents, where the item Title field contains a specified value.
