FileDialog.AddExtension FileDialog.AddExtension FileDialog.AddExtension FileDialog.AddExtension Property

Definition

Gets or sets a value indicating whether the dialog box automatically adds an extension to a file name if the user omits the extension.

public:
 property bool AddExtension { bool get(); void set(bool value); };
public bool AddExtension { get; set; }
member this.AddExtension : bool with get, set
Public Property AddExtension As Boolean

Property Value

true if the dialog box adds an extension to a file name if the user omits the extension; otherwise, false. The default value is true.

Remarks

The extension added to a file name depends on the currently selected file filter and the value of the CheckFileExists property.

If the CheckFileExists property is true, the dialog box adds the first extension from the current file filter that matches an existing file. If no files match the current file filter, the dialog box adds the extension specified in the DefaultExt property.

If the CheckFileExists property is false, the dialog box adds the first valid file name extension from the current file filter. If the current file filter contains no valid file name extensions, the dialog box adds the extension specified in the DefaultExt property.

Security

FileIOPermission
for adding an extension if the user omits it. Associated enumeration: Unrestricted.
