FileIOPermissionAttribute.PathDiscovery Property

Definition

Gets or sets the file or directory to which to grant path discovery.

C#
public string PathDiscovery { get; set; }

Property Value

The absolute path of the file or directory.

Examples

The following code example sets the PathDiscovery property to grant PathDiscovery access to files in the specified directory.

C#
// Set the PathDiscovery property.
[FileIOPermissionAttribute(SecurityAction.PermitOnly,
     PathDiscovery = "C:\\Documents and Settings\\All Users")]

Remarks

Path discovery controls access to the information in the path itself. This helps protect sensitive information in the path, such as user names, as well as information about the directory structure revealed in the path. This value does not grant access to files or folders represented by the path.

Note

For performance reasons, PathDiscovery should be granted only to directories, not to files. For example, PathDiscovery permission should be granted to paths such as C:\test and C:\test\, not to files such as C:\test\example.txt.

This property sets access for a single file or directory. Use additional attributes to specify additional files and directories.
