FileUpload.FileName Property

Note: This property is new in the .NET Framework version 2.0.

Gets the name of a file on a client to upload using the FileUpload control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public string FileName { get; }
/** @property */
public String get_FileName ()

public function get FileName () : String

Property Value

A string that specifies the name of a file on a client to upload using the FileUpload.

Gets the name of a file on a client to upload using the FileUpload control. The file name that the FileName property returns does not include the path to the file on the client.

The following code example demonstrates how to create a FileUpload control that saves files to a path that is specified in code. The FileName property is used to get the name of the file to upload. The SaveAs method is called to save the file to the specified path on the server, using the same name the file has on the client. Note that this example demonstrates the basic syntax for this control, but does not demonstrate all the necessary error checking that should be done prior to saving the file. For a more complete example, see SaveAs.
