ReflectionPermission Class

 

Controls access to non-public types and members through the System.Reflection APIs. Controls some features of the System.Reflection.Emit APIs.

Namespace:   System.Security.Permissions

NameDescription
System_CAPS_pubmethodReflectionPermission(PermissionState)

Initializes a new instance of the ReflectionPermission class with either fully restricted or unrestricted permission as specified.

System_CAPS_pubmethodReflectionPermission(ReflectionPermissionFlag)

Initializes a new instance of the ReflectionPermission class with the specified access.

NameDescription
System_CAPS_pubpropertyFlags

Gets or sets the type of reflection allowed for the current permission.

NameDescription
System_CAPS_pubmethodAssert()

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.)

System_CAPS_pubmethodCopy()

Creates and returns an identical copy of the current permission.(Overrides CodeAccessPermission.Copy().)

System_CAPS_pubmethodDemand()

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.)

System_CAPS_pubmethodDeny()

Obsolete.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.)

System_CAPS_pubmethodEquals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodFromXml(SecurityElement)

Reconstructs a permission with a specified state from an XML encoding.(Overrides CodeAccessPermission.FromXml(SecurityElement).)

System_CAPS_pubmethodGetHashCode()

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.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIntersect(IPermission)

Creates and returns a permission that is the intersection of the current permission and the specified permission.(Overrides CodeAccessPermission.Intersect(IPermission).)

System_CAPS_pubmethodIsSubsetOf(IPermission)

Determines whether the current permission is a subset of the specified permission.(Overrides CodeAccessPermission.IsSubsetOf(IPermission).)

System_CAPS_pubmethodIsUnrestricted()

Returns a value indicating whether the current permission is unrestricted.

System_CAPS_pubmethodPermitOnly()

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.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current permission object.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodToXml()

Creates an XML encoding of the permission and its current state.(Overrides CodeAccessPermission.ToXml().)

System_CAPS_pubmethodUnion(IPermission)

Creates a permission that is the union of the current permission and the specified permission.(Overrides CodeAccessPermission.Union(IPermission).)

Without ReflectionPermission, code can use reflection to access only the public members of objects. Code with ReflectionPermission and the appropriate ReflectionPermissionFlag flags can access the protected and private members of objects.

System_CAPS_cautionCaution

Because ReflectionPermission can provide access to non-public types and members, we recommend that you do not grant ReflectionPermission to Internet code, except with the ReflectionPermissionFlag.RestrictedMemberAccess flag. RestrictedMemberAccess allows access to non-public members, with the restriction that the grant set of the non-public members must be equal to, or a subset of, the grant set of the code that accesses the non-public members.

Certain features of reflection emit, such as emitting debug symbols, require ReflectionPermission with the ReflectionPermissionFlag.ReflectionEmit flag.

For more information, see the ReflectionPermissionFlag enumeration.
