DnsPermission Class
Visual Studio 2010
Controls rights to access Domain Name System (DNS) servers on the network.
Assembly: System (in System.dll)
The DnsPermission type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | DnsPermission | Creates a new instance of the DnsPermission class that either allows unrestricted DNS access or disallows DNS access. |
| Name | Description | |
|---|---|---|
![]() | 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 an identical copy of the current permission instance. (Overrides CodeAccessPermission::Copy().) |
![]() | 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. 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 | Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | FromXml | Reconstructs a DnsPermission instance from an XML encoding. (Overrides CodeAccessPermission::FromXml(SecurityElement).) |
![]() | 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 | Creates a permission instance that is the intersection of the current permission instance and the specified permission instance. (Overrides CodeAccessPermission::Intersect(IPermission).) |
![]() | IsSubsetOf | Determines whether the current permission instance is a subset of the specified permission instance. (Overrides CodeAccessPermission::IsSubsetOf(IPermission).) |
![]() | IsUnrestricted | Checks the overall permission state of the object. |
![]() | 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 a DnsPermission instance and its current state. (Overrides CodeAccessPermission::ToXml().) |
![]() | Union | Creates a permission instance that is the union of the current permission instance and the specified permission instance. (Overrides CodeAccessPermission::Union(IPermission).) |
