Property Value

Type: System.String

A string that contains information about the file filtering options available in the dialog box.

The Filter property specifies a filter string for all files (*.*).

A filter string contains one or more filter options. Each filter option contains a description of the filter, followed by the vertical bar (|) and the filter pattern. The strings for different filtering options are separated by the vertical bar.

The following is an example of a filter string that contains two filter options:

"Text Files (*.txt)|*.txt|All Files (*.*)|*.*".

You can specify several filter patterns in a filter option by separating the filter patterns with semicolons. The following is an example of a filter string in which the first filter option specifies three filter patterns:

"Text Files(*.txt;*.text;*.lst)|*.txt;*.text;*.lst|All Files (*.*)|*.*".
