Caution

Code Access Security is not supported or honored by the runtime.

Represents access to generic isolated storage capabilities.

Remarks

This class is an abstract base class. This class is never instantiated; instead, classes that extend it and represent access to a particular type of isolated storage are used.

Constructors

IsolatedStoragePermission(PermissionState)

Initializes a new instance of the IsolatedStoragePermission class with either restricted or unrestricted permission as specified.

Properties

UsageAllowed

Gets or sets the type of isolated storage containment allowed.

UserQuota

Gets or sets the quota on the overall size of each user's total store.

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()

When implemented by a derived class, creates and returns an identical copy of the current permission object.

(Inherited from CodeAccessPermission)
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)

When implemented by a derived class, creates and returns a permission that is the intersection of the current permission and the specified permission.

(Inherited from CodeAccessPermission)
IsSubsetOf(IPermission)

When implemented by a derived class, determines whether the current permission is a subset of the specified permission.

(Inherited from CodeAccessPermission)
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)

When overridden in a derived class, creates a permission that is the union of the current permission and the specified permission.

(Inherited from CodeAccessPermission)

Explicit Interface Implementations

IPermission.Demand()

Throws a SecurityException at run time if the security requirement is not met.

(Inherited from CodeAccessPermission)
IStackWalk.Assert()

Asserts that the calling code can access the resource identified by the current permission object, even if callers higher in the stack have not been granted permission to access the resource.

(Inherited from CodeAccessPermission)
IStackWalk.Demand()

Determines at run time whether all callers in the call stack have been granted the permission specified by the current permission object.

(Inherited from CodeAccessPermission)
IStackWalk.Deny()

Causes every Demand() for the current object that passes through the calling code to fail.

(Inherited from CodeAccessPermission)
IStackWalk.PermitOnly()

Causes every Demand() for all objects except the current one that pass through the calling code to fail, even if code higher in the call stack has been granted permission to access other resources.
