Examples

The following example creates an unrestricted permission object.

System::Net::NetworkInformation::NetworkInformationPermission^ unrestricted = gcnew System::Net::NetworkInformation::NetworkInformationPermission( System::Security::Permissions::PermissionState::Unrestricted );

System.Net.NetworkInformation.NetworkInformationPermission unrestricted = 
    new System.Net.NetworkInformation.NetworkInformationPermission(
        System.Security.Permissions.PermissionState.Unrestricted);
Dim unrestricted As New System.Net.NetworkInformation.NetworkInformationPermission( _
    System.Security.Permissions.PermissionState.Unrestricted)

Remarks

This permission is used to secure data returned by the classes in the System.Net.NetworkInformation namespace.

For declarative security, use the NetworkInformationPermissionAttribute class.

Constructors

NetworkInformationPermission(NetworkInformationAccess) NetworkInformationPermission(NetworkInformationAccess) NetworkInformationPermission(NetworkInformationAccess) NetworkInformationPermission(NetworkInformationAccess)

Initializes a new instance of the NetworkInformationPermission class using the specified NetworkInformationAccess value.

NetworkInformationPermission(PermissionState) NetworkInformationPermission(PermissionState) NetworkInformationPermission(PermissionState) NetworkInformationPermission(PermissionState)

Initializes a new instance of the NetworkInformationPermission class with the specified PermissionState.

Properties

Access Access Access Access

Gets the level of access to network information controlled by this permission.

Methods

AddPermission(NetworkInformationAccess) AddPermission(NetworkInformationAccess) AddPermission(NetworkInformationAccess) AddPermission(NetworkInformationAccess)

Adds the specified value to this permission.

Assert() Assert() Assert() 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() Copy() Copy() Copy()

Creates and returns an identical copy of this permission.

Demand() Demand() Demand() 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() Deny() Deny() Deny()

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) Equals(Object) Equals(Object) Equals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(Inherited from CodeAccessPermission)
FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement)

Sets the state of this permission using the specified XML encoding.

GetHashCode() GetHashCode() GetHashCode() 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() GetType() GetType() GetType()

Gets the Type of the current instance.

(Inherited from Object)
Intersect(IPermission) Intersect(IPermission) Intersect(IPermission) Intersect(IPermission)

Creates and returns a permission that is the intersection of the current permission and the specified permission.

IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission)

Determines whether the current permission is a subset of the specified permission.

IsUnrestricted() IsUnrestricted() IsUnrestricted() IsUnrestricted()

Returns a value indicating whether the current permission is unrestricted.

MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
PermitOnly() PermitOnly() PermitOnly() 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() ToString() ToString() ToString()

Creates and returns a string representation of the current permission object.

(Inherited from CodeAccessPermission)
ToXml() ToXml() ToXml() ToXml()

Creates an XML encoding of the state of this permission.

Union(IPermission) Union(IPermission) Union(IPermission) Union(IPermission)

Creates a permission that is the union of this permission and the specified permission.
