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

System::Object
  System.Security::CodeAccessPermission
    System.Security.Permissions::MediaPermission

[SerializableAttribute]
public ref class MediaPermission sealed : CodeAccessPermission, 
	IUnrestrictedPermission

NameDescription
System_CAPS_pubmethodMediaPermission()

Initializes a new instance of the MediaPermission class.

System_CAPS_pubmethodMediaPermission(MediaPermissionAudio)

Initializes a new instance of the MediaPermission class by specifying the audio permission level.

System_CAPS_pubmethodMediaPermission(MediaPermissionAudio, MediaPermissionVideo, MediaPermissionImage)

Initializes a new instance of the MediaPermission class by specifying the audio, video, and image permission levels.

System_CAPS_pubmethodMediaPermission(MediaPermissionImage)

Initializes a new instance of the MediaPermission class by specifying the image permission level.

System_CAPS_pubmethodMediaPermission(MediaPermissionVideo)

Initializes a new instance of the MediaPermission class by specifying the video permission level.

System_CAPS_pubmethodMediaPermission(PermissionState)

Initializes a new instance of the MediaPermission class by specifying a permission state.

NameDescription
System_CAPS_pubpropertyAudio

Gets the current value of the audio permission level.

System_CAPS_pubpropertyImage

Gets the current value of the image permission level.

System_CAPS_pubpropertyVideo

Gets the current value of the video permission level.

NameDescription
System_CAPS_pubmethodAssert()

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.)

System_CAPS_pubmethodCopy()

Creates and returns an identical copy of the current permission.(Overrides CodeAccessPermission::Copy().)

System_CAPS_pubmethodDemand()

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.)

System_CAPS_pubmethodDeny()

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.)

System_CAPS_pubmethodEquals(Object^)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodFromXml(SecurityElement^)

Reconstructs a permission with a specified state from an XML encoding.(Overrides CodeAccessPermission::FromXml(SecurityElement^).)

System_CAPS_pubmethodGetHashCode()

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.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIntersect(IPermission^)

Creates and returns a permission that is the intersection of the current permission and the specified permission.(Overrides CodeAccessPermission::Intersect(IPermission^).)

System_CAPS_pubmethodIsSubsetOf(IPermission^)

Determines whether the current permission is a subset of the specified permission.(Overrides CodeAccessPermission::IsSubsetOf(IPermission^).)

System_CAPS_pubmethodIsUnrestricted()

Returns a value indicating whether the current permission is unrestricted.

System_CAPS_pubmethodPermitOnly()

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.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current permission object.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodToXml()

Creates an XML encoding of the permission and its current state.(Overrides CodeAccessPermission::ToXml().)

System_CAPS_pubmethodUnion(IPermission^)

Creates a permission that is the union of the current permission and the specified permission.(Overrides CodeAccessPermission::Union(IPermission^).)

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