Parameters

target

The System.Net.DnsPermission instance to intersect with the current instance.

Returns

A System.Net.DnsPermission instance that represents the intersection of the current System.Net.DnsPermission instance with the specified System.Net.DnsPermission instance, or null if the intersection is empty. If both the current instance and target are unrestricted, this method returns a new System.Net.DnsPermission instance that is unrestricted; otherwise, it returns null.

Exceptions

Type	Reason
ArgumentNullException	target is null.

Remarks

The DnsPermission.Intersect(System.Security.IPermission) method returns a System.Net.DnsPermission instance that allows the access defined by both the current System.Net.DnsPermission instance and the specified System.Net.DnsPermission instance. Any demand must pass both permissions to pass their intersection.
