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 is typically used to provide limited access to user-specified files when FileIOPermission is not granted.

Constructors

FileDialogPermission(FileDialogPermissionAccess)	Initializes a new instance of the FileDialogPermission class with the specified access.
FileDialogPermission(PermissionState)	Initializes a new instance of the FileDialogPermission class with either restricted or unrestricted permission, as specified.

Properties

Access

Gets or sets the permitted access to files.

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 a string representation of the current permission.
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.
