UrlIdentityPermission UrlIdentityPermission UrlIdentityPermission UrlIdentityPermission Class

Definition

Defines the identity permission for the URL from which the code originates. This class cannot be inherited.

Remarks

The complete URL is considered, including the protocol (HTTP, HTTPS, FTP) and the file. For example, http://www.fourthcoffee.com/process/grind.htm is a complete URL.

URLs can be matched exactly or by a wildcard in the final position, for example: http://www.fourthcoffee.com/process/*. URLs can also contain a wildcard ("*") prefix at the dot delimiter. For example, the URL name string http://www.fourthcoffee.com/process/grind.htm/ is a subset of http://*.fourthcoffee.com/process/grind.htm/ and http://*.com/process/grind.htm/.

Important

Starting with the .NET Framework 4, identity permissions are not used.

In the .NET Framework versions 1.0 and 1.1, demands on the identity permissions are effective even when the calling assembly is fully trusted. That is, although the calling assembly has full trust, a demand for an identity permission fails if the assembly does not meet the demanded criteria. Starting with the .NET Framework version 2.0, demands for identity permissions are ineffective if the calling assembly has full trust. That is, a demand for an identity always succeeds, regardless of the identity of the assembly, if the assembly has been granted full trust. This assures consistency for all permissions, eliminating the treatment of identity permissions as a special case.

Note

In versions of the .NET Framework before the .NET Framework 4, you could use the CodeAccessPermission.Deny method to prevent inadvertent access to system resources by trusted code. Deny is now obsolete, and access to resources is now determined solely by the granted permission set for an assembly. To limit access to files, you must run partially trusted code in a sandbox and assign it permissions only to resources that the code is allowed to access. For information about running an application in a sandbox, see How to: Run Partially Trusted Code in a Sandbox.

Note

In the .NET Framework versions 1.0 and 1.1, identity permissions cannot have an Unrestricted permission state value. Starting with the .NET Framework version 2.0, identity permissions can have any permission state value. This means that in 2.0 and later versions, identity permissions have the same behavior as permissions that implement the IUnrestrictedPermission interface.

Constructors

UrlIdentityPermission(PermissionState) UrlIdentityPermission(PermissionState) UrlIdentityPermission(PermissionState) UrlIdentityPermission(PermissionState)

Initializes a new instance of the UrlIdentityPermission class with the specified PermissionState.

UrlIdentityPermission(String) UrlIdentityPermission(String) UrlIdentityPermission(String) UrlIdentityPermission(String)

Initializes a new instance of the UrlIdentityPermission class to represent the URL identity described by site.

Properties

Url Url Url Url

Gets or sets a URL representing the identity of Internet code.

Methods

Assert() Assert() Assert() Assert()

Declares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert() can create security issues.

(Inherited from CodeAccessPermission)
Copy() Copy() Copy() Copy()

Creates and returns an identical copy of the current permission.

Demand() Demand() Demand() Demand()

Forces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance.

(Inherited from CodeAccessPermission)
Deny() Deny() Deny() Deny()

Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance.

(Inherited from CodeAccessPermission)
Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(Inherited from CodeAccessPermission)
FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement)

Reconstructs a permission with a specified state from an XML encoding.

GetHashCode() GetHashCode() GetHashCode() GetHashCode()

Gets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table.

(Inherited from CodeAccessPermission)
GetType() GetType() GetType() GetType()

Gets the Type of the current instance.

(Inherited from Object)
Intersect(IPermission) Intersect(IPermission) Intersect(IPermission) Intersect(IPermission)

Creates and returns a permission that is the intersection of the current permission and the specified permission.

IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission)

Determines whether the current permission is a subset of the specified permission.

MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
PermitOnly() PermitOnly() PermitOnly() PermitOnly()

Prevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance.

(Inherited from CodeAccessPermission)
ToString() ToString() ToString() ToString()

Creates and returns a string representation of the current permission object.

(Inherited from CodeAccessPermission)
ToXml() ToXml() ToXml() ToXml()

Creates an XML encoding of the permission and its current state.

Union(IPermission) Union(IPermission) Union(IPermission) Union(IPermission)

Creates a permission that is the union of the current permission and the specified permission.
