FileCodeGroup.ResolveMatchingCodeGroups(Evidence) Method

Definition

Namespace:

System.Security.Policy

Assembly:

System.Security.Permissions.dll

Resolves matching code groups.

public:
 override System::Security::Policy::CodeGroup ^ ResolveMatchingCodeGroups(System::Security::Policy::Evidence ^ evidence);

public override System.Security.Policy.CodeGroup ResolveMatchingCodeGroups (System.Security.Policy.Evidence evidence);

override this.ResolveMatchingCodeGroups : System.Security.Policy.Evidence -> System.Security.Policy.CodeGroup

Public Overrides Function ResolveMatchingCodeGroups (evidence As Evidence) As CodeGroup

Parameters

evidence

Evidence

The evidence for the assembly.

Returns

CodeGroup

A CodeGroup that is the root of the tree of matching code groups.

Exceptions

ArgumentNullException

The evidence parameter is null.

Examples

The following code shows the use of the ResolveMatchingCodeGroups method to resolve matching code groups. This code example is part of a larger example provided for the FileCodeGroup class.

Assembly^ assembly = Members::typeid->Assembly;
Evidence^ evidence = assembly->Evidence;
CodeGroup^ codeGroup = fileCodeGroup->ResolveMatchingCodeGroups( evidence );

Assembly assembly = typeof(Members).Assembly;
Evidence evidence = assembly.Evidence;
CodeGroup codeGroup = 
    fileCodeGroup.ResolveMatchingCodeGroups(evidence);

Dim executingAssembly As [Assembly]
executingAssembly = Me.GetType().Assembly

Dim evidence As Evidence = executingAssembly.Evidence

Dim codeGroup As CodeGroup
codeGroup = fileCodeGroup.ResolveMatchingCodeGroups(evidence)

Remarks

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 root code group. The code group that is returned contains child code groups, which in turn can have child code groups as necessary to reflect the complete set of code groups that were matched by the evidence provided.

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