The MediaPermission describes a set of security permissions that controls the ability for audio, image, and video media to work in a partial-trust Windows Presentation Foundation (WPF) application.

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

This permission uses the values of the MediaPermissionAudio, MediaPermissionImage, and MediaPermissionVideo enumerations.

Constructors

MediaPermission()	Initializes a new instance of the MediaPermission class.
MediaPermission(MediaPermissionAudio, MediaPermissionVideo, MediaPermissionImage)	Initializes a new instance of the MediaPermission class by specifying the audio, video, and image permission levels.
MediaPermission(MediaPermissionAudio)	Initializes a new instance of the MediaPermission class by specifying the audio permission level.
MediaPermission(MediaPermissionImage)	Initializes a new instance of the MediaPermission class by specifying the image permission level.
MediaPermission(MediaPermissionVideo)	Initializes a new instance of the MediaPermission class by specifying the video permission level.
MediaPermission(PermissionState)	Initializes a new instance of the MediaPermission class by specifying a permission state.

Properties

Audio	Gets the current value of the audio permission level.
Image	Gets the current value of the image permission level.
Video	Gets the current value of the video permission level.

Methods

Assert()	Declares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert() can create security issues. (Inherited from CodeAccessPermission)
Copy()	Creates and returns an identical copy of the current permission.
Demand()	Forces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance. (Inherited from CodeAccessPermission)
Deny()	Obsolete. Obsolete. Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance. (Inherited from CodeAccessPermission)
Equals(Object)	Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission)
FromXml(SecurityElement)	Reconstructs a permission with a specified state from an XML encoding.
GetHashCode()	Gets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table. (Inherited from CodeAccessPermission)
GetType()	Gets the Type of the current instance. (Inherited from Object)
Intersect(IPermission)	Creates and returns a permission that is the intersection of the current permission and the specified permission.
IsSubsetOf(IPermission)	Determines whether the current permission is a subset of the specified permission.
IsUnrestricted()	Returns a value indicating whether the current permission is unrestricted.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
PermitOnly()	Prevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance. (Inherited from CodeAccessPermission)
ToString()	Creates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission)
ToXml()	Creates an XML encoding of the permission and its current state.
Union(IPermission)	Creates a permission that is the union of the current permission and the specified permission.
