Checks the overall permission state of the object.

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

public final function IsUnrestricted() : boolean

Return Value

Type: System.Boolean
true if the SocketPermission instance is created with the Unrestricted value from PermissionState; otherwise, false.

Implements

IUnrestrictedPermission.IsUnrestricted()

The following example checks the IsUnrestricted property to determine if the specified SocketPermission has any restrictions.

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' 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");
