SocketPermission.Union Method

Returns the logical union between two SocketPermission instances.

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

abstract Union : 
        target:IPermission -> IPermission  
override Union : 
        target:IPermission -> IPermission

Parameters

target
Type: System.Security.IPermission

The SocketPermission instance to combine with the current instance.

Return Value

Type: System.Security.IPermission
The SocketPermission instance that represents the union of two SocketPermission instances. If target parameter is a null reference (Nothing in Visual Basic), it returns a copy of the current instance.

Implements

IPermission.Union(IPermission)

ExceptionCondition
ArgumentException

target is not a SocketPermission.

The result of a call to Union is a permission that represents all of the access to Socket connections represented by the current instance as well as the access represented by target. Any demand that passes either the current instance or target passes their union. This method overrides Union and is implemented to support the IPermission interface.

The following example uses the Union method to return the logical union of two existing SocketPermission instances.
