SocketPermission.ToXml Method

Creates an XML encoding of a SocketPermission instance and its current state.

Namespace:  System.Net
Assembly:  System (in System.dll)

public override function ToXml() : SecurityElement

Return Value

Type: System.Security.SecurityElement
A SecurityElement instance that contains an XML-encoded representation of the SocketPermission instance, including state information.

Implements

ISecurityEncodable.ToXml()

The ToXml method creates a SecurityElement instance to encode a representation of the SocketPermission instance, including state information, in XML.

Use the FromXml method to restore the state information from a SecurityElement instance.

The following example uses the ToXml method to convert a SocketPermission to XML.

No code example is currently available or this language may not be supported.
SocketPermission* socketPermission1 = new SocketPermission(PermissionState::Unrestricted);

// Create a 'SocketPermission' Object* for two ip addresses.
SocketPermission* socketPermission2 = new SocketPermission(PermissionState::None);
SecurityElement*  securityElement4 = socketPermission2->ToXml();
// 'SocketPermission' Object* for 'Connect' permission
SecurityElement* securityElement1 = new SecurityElement(S"ConnectAccess");
// Format to specify ip address are <ip-address>#<port>#<transport-type>
// First 'SocketPermission' ip-address is '192.168.144.238' for 'All' transport types and for 'All' ports for the ip-address.
SecurityElement* securityElement2 = new SecurityElement(S"URI", S"192.168.144.238#-1#3");
// Second 'SocketPermission' ip-address is '192.168.144.240' for 'All' transport types and for 'All' ports for the ip-address.

// Obtain a 'SocketPermission' Object* using 'FromXml' method.
socketPermission2->FromXml(securityElement4);

// Create another 'SocketPermission' Object* with two ip addresses.
