HostSecurityManager.ProvideAppDomainEvidence Method

Provides the application domain evidence for an assembly being loaded.

Namespace: System.Security
Assembly: mscorlib (in mscorlib.dll)

public virtual Evidence ProvideAppDomainEvidence (
	Evidence inputEvidence
public Evidence ProvideAppDomainEvidence (
	Evidence inputEvidence
public function ProvideAppDomainEvidence (
	inputEvidence : Evidence
) : Evidence
Not applicable.



Additional Evidence to add to the AppDomain evidence.

Return Value

An Evidence object representing the evidence to be used for the AppDomain.

This method can be overridden in a derived class.

This method is called whenever an assembly is loaded, either implicitly or explicitly. The inputEvidence parameter is the computed evidence from the common language runtime. The host implementation can choose to extend or reduce the evidence. The return value is the evidence to be used for the application domain. The base implementation always returns the evidence object passed in asthe inputEvidence parameter.


See the Notes to Inheritors for the HostSecurityManager class for critical implementation information.

The following code example shows an override of the ProvideAppDomainEvidence method for a custom host security manager. This example is part of a larger example provided for the HostSecurityManager class.

public override Evidence ProvideAppDomainEvidence(Evidence evidence)
    Console.WriteLine("Provide evidence for the " + AppDomain.CurrentDomain.FriendlyName + " AppDomain." );
    if (evidence == null)
        return null;

    evidence.AddHost(new CustomEvidenceType());
    return evidence;
