Parameters

target

A System.Net.DnsPermission instance to combine with the current instance. [Edit]

Returns

A new System.Net.DnsPermission instance that represents the union of the current instance and target. If the current instance or target is unrestricted, returns a System.Net.DnsPermission instance that is unrestricted. [Edit]

Exceptions

Type	Reason
ArgumentNullException	target is null. [Edit]

Remarks

Note:

The result of a call to DnsPermission.Union(System.Security.IPermission) is a permission that represents all of the access to permissions represented by the current instance as well as the permissions represented by target. Any demand that passes either the current instance or target passes their union.

This method overrides System.Security.CodeAccessPermission.Union(System.Security.IPermission) and is implemented to support the System.Security.IPermission interface.
