Definition

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

public:
 property System::String ^ FileName { System::String ^ get(); };
[System.ComponentModel.Browsable(false)]
public string FileName { get; }
member this.FileName : string
Public ReadOnly Property FileName As String

Property Value

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

Examples

The following 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 before saving the file. For a more complete example, see SaveAs.
