WebBrowserPermissionLevel Enumeration

.NET Framework 4.5

Specifies the permission level for a Web browser.

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

public enum WebBrowserPermissionLevel

XAML Attribute Usage

<object property="enumerationMemberName" .../>

	Member name	Description
	None	A Web browser that cannot navigate frames to HTML.
	Safe	A Web browser that can safely navigate frames to HTML but with several restrictions.
	Unrestricted	A Web browser that can navigate without restrictions.

Use this enumeration to set the Level property of the WebBrowserPermission class.

The Safe permission level restricts the following Web browser operations.

A pop-up window cannot be created over the Web browser control.
The Web browser control can only be navigated to its site of origin.
The security settings of the Web browser control are reduced.

The following example shows how to demand that the calling code has unrestricted permission to create a Web browser control.

[WebBrowserPermissionAttribute(SecurityAction.Demand, Level = WebBrowserPermissionLevel.Unrestricted)]
