System.Security.Policy.Zone Class

Summary

Provides the security zone of a code assembly as evidence for policy evaluation. This class cannot be inherited.

C# Syntax:

[Serializable] public sealed class Zone : IIdentityPermissionFactory

The presence of Zone evidence produces a ZoneIdentityPermission in the grant set. If there is a CodeAccessPermission.Demand for ZoneIdentityPermission, the ZoneIdentityPermission that corresponds to the Zone evidence will be compared with the demanded permission.

Zones are defined by the SecurityZone enumeration.

Summary

Gets the zone from which the code assembly originates.

C# Syntax:

public SecurityZone SecurityZone {get;}

Summary

Creates an equivalent copy of the evidence object.

C# Syntax:

public object Copy();

Return Value:

A new, identical copy of the evidence object.

Return to top

Summary

Creates a new zone with the specified URL.

C# Syntax:

public static Zone CreateFromUrl(    string url );

url

The URL from which to create the zone.

Return Value:

A new zone with the specified URL.

Exceptions

Exception Type	Condition
ArgumentNullException	The url parameter is null.

The zone determination for the specified URL is based on the zone mapping settings in Microsoft Internet Explorer and can therefore differ from computer to computer. The zone mapping settings are located on the Security tab of the Internet Options dialog launched from the Tools menu.

Summary

Creates an identity permission that corresponds to the current instance of the Zone evidence class.

C# Syntax:

public IPermission CreateIdentityPermission(    Evidence evidence );

evidence

The evidence set from which to construct the identity permission.

Return Value:

A ZoneIdentityPermission for the specified Zone evidence.

Implements:

IIdentityPermissionFactory.CreateIdentityPermission

Summary

Compares the current Zone evidence object to the specified object for equivalence.

C# Syntax:

public override bool Equals(    object o );

o

The Zone evidence object to test for equivalence with the current object.

Return Value:

true if the two Zone objects are equal; otherwise, false.

Exceptions

Exception Type	Condition
ArgumentException	The o parameter is not a Zone object.

Zone objects are equal if they designate the same SecurityZone.
