RegistryPermission.GetPathList Method

Gets paths for all registry variables with the specified RegistryPermissionAccess.

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

public string GetPathList (
	RegistryPermissionAccess access
)
public String GetPathList (
	RegistryPermissionAccess access
)
public function GetPathList (
	access : RegistryPermissionAccess
) : String

Parameters

access

One of the RegistryPermissionAccess values that represents a single type of registry variable access.

Return Value

A list of the registry variables (semicolon-separated) with the specified RegistryPermissionAccess.

Exception typeCondition

ArgumentException

access is not a valid value of RegistryPermissionAccess.

-or-

access is AllAccess, which represents more than one type of registry variable access, or NoAccess, which does not represent any type of registry variable access.

Use this method to get the state of the current permission. You must call this method separately for each type of access.

NoteNote

The access parameter is limited to the values of RegistryPermissionAccess, which represent single types of registry variable access. Those values are Read, Write, and Create. The values acceptable to access do not include NoAccess and AllAccess, which do not represent single types of registry variable access.

The following code example shows the use of the GetPathList method. This code example is part of a larger example provided for the RegistryPermission class.

// AddPathList adds access for the specified registry variables to the existing state of the permission.
// SetPathList sets new access for the specified registry variable names to the existing state of the permission.
// GetPathList gets paths for all registry variables with the specified RegistryPermissionAccess.

        Console.WriteLine("Adding 'HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION' to the write access list, "
            + "and \n 'HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\FloatingPointProcessor\\0' "
