Namespace: Microsoft.Win32
Assembly: PresentationFramework (in PresentationFramework.dll)

Public Function OpenFiles As Stream()

Return Value

Type: System.IO.Stream()
An array of multiple new Stream objects that contain the selected files.

Exceptions

InvalidOperationException	No files were selected in the dialog.

Remarks

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