OpenFileDialog.OpenFile Method

Definition

Opens a read-only stream for the file that is selected by the user using OpenFileDialog.

public:
 System::IO::Stream ^ OpenFile();
[System.Security.SecurityCritical]
public System.IO.Stream OpenFile ();
member this.OpenFile : unit -> System.IO.Stream
Public Function OpenFile () As Stream

Returns

A new Stream that contains the selected file.

Attributes

Exceptions

No files were selected in the dialog.

Remarks

The file is opened with read-only permission (Open, Read, and Read), whether or not the Read Only checkbox is checked in the dialog. Because the file is opened without the ability to overwrite or write to the file, an application can safely load a file while executing within partial trust restrictions.

If more than one file is selected, the first selected file is opened.
