FileCodeGroup.Resolve(Evidence) Method


Resolves policy for the code group and its descendants for a set of evidence.

 override System::Security::Policy::PolicyStatement ^ Resolve(System::Security::Policy::Evidence ^ evidence);
public override System.Security.Policy.PolicyStatement Resolve (System.Security.Policy.Evidence evidence);
override this.Resolve : System.Security.Policy.Evidence -> System.Security.Policy.PolicyStatement



The evidence for the assembly.


A policy statement consisting of the permissions granted by the code group with optional attributes, or null if the code group does not apply (the membership condition does not match the specified evidence).


The evidence parameter is null.

The current policy is null.


More than one code group (including the parent code group and all child code groups) is marked Exclusive.


The following code shows the use of the Resolve method to resolve policy for the code group. This code example is part of a larger example provided for the FileCodeGroup class.

Assembly^ assembly = Members::typeid->Assembly;
Evidence^ executingEvidence = assembly->Evidence;
PolicyStatement^ policy = fileCodeGroup->Resolve( executingEvidence );
Assembly assembly = typeof(Members).Assembly;
Evidence executingEvidence = assembly.Evidence;

PolicyStatement policy = fileCodeGroup.Resolve(executingEvidence);
Dim executingAssembly As [Assembly]
executingAssembly = Me.GetType().Assembly

Dim executingEvidence As Evidence = executingAssembly.Evidence

Dim policy As PolicyStatement
policy = fileCodeGroup.Resolve(executingEvidence)


Given evidence for an assembly to be loaded, this method evaluates the code group by first checking the membership condition against the specified evidence. If there is a match, this method returns a policy statement for the code group, including evaluation of child code groups.

The .NET Framework security system uses Resolve on the policy levels to determine which permissions to grant to loaded code from the resulting policy statements and the code request on the assembly.

FileCodeGroup uses union semantics and forms a permission set based on the Url specified by evidence.
