Caution

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

The WebBrowserPermission object controls the ability to create the WebBrowser control.

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.

In Windows Presentation Foundation (WPF), the Web browser control enables frames to navigate HTML. This permission uses the values of the WebBrowserPermission enumerations.

This class is not typically used in XAML.

Constructors

WebBrowserPermission()	Initializes a new instance of the WebBrowserPermission class.
WebBrowserPermission(PermissionState)	Initializes a new instance of the WebBrowserPermission class by specifying a permission state.
WebBrowserPermission(WebBrowserPermissionLevel)	Initializes a new instance of the WebBrowserPermission class by specifying the Web browser permission level.

Properties

Level

Gets or sets the current value of the Web browser 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.
