Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

[AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)]
public ref class HttpFileCollection sealed : public NameObjectCollectionBase

Clients encode files and transmit them in the content body using multipart MIME format with an HTTP Content-Type header of multipart/form-data. ASP.NET extracts the encoded file(s) from the content body into individual members of an HttpFileCollection. Methods and properties of the HttpPostedFile class provide access to the contents and properties of each file.

The following example demonstrates how to access the HttpFileCollection collection returned from the Files property of the HttpRequest object. The HttpFileCollection collection is populated by two FileUpload controls on the Web page. Items in the file collection are displayed in a BulletedList control.
