Property Value

Type: System::String^

The default extension string. The default is Empty.

The extension string must contain the leading period. For example, set the DefaultExt property to ".txt" to select all text files.

By default, the AddExtension property attempts to determine the extension to filter the displayed file list from the Filter property. If the extension cannot be determined from the Filter property, DefaultExt will be used instead.

The following example shows how to create an OpenFileDialog that contains a default file name and extension type.
