FileIOPermissionAttribute.PathDiscovery Property

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

Namespace: System.Security.Permissions
Assembly: mscorlib (in mscorlib.dll)

public string PathDiscovery { get; set; }
/** @property */
public String get_PathDiscovery ()

/** @property */
public void set_PathDiscovery (String value)

public function get PathDiscovery () : String

public function set PathDiscovery (value : String)

Property Value

The absolute path of the file or directory.

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.


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

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

    // Set the PathDiscovery property.
     PathDiscovery = "C:\\Documents and Settings\\All Users")]

// Set the PathDiscovery property.
/** @attribute FileIOPermissionAttribute(SecurityAction.PermitOnly, 
    PathDiscovery = "C:\\Documents and Settings\\All Users")
