Evidence Constructors

Definition

Initializes a new instance of the Evidence class.

Overloads

Evidence()

Initializes a new empty instance of the Evidence class.

Evidence(Evidence)

Initializes a new instance of the Evidence class from a shallow copy of an existing one.

Evidence(Object[], Object[])

Initializes a new instance of the Evidence class from multiple sets of host and assembly evidence.

Evidence(EvidenceBase[], EvidenceBase[])

Initializes a new instance of the Evidence class from multiple sets of host and assembly evidence.

Evidence()

Initializes a new empty instance of the Evidence class.

public:
 Evidence();
public Evidence ();
Public Sub New ()

Examples

The following code example shows the use of the Evidence() constructor. This example is part of a larger example provided for the Evidence class.

Evidence^ ev1 = gcnew Evidence;
Console::WriteLine( "Created empty evidence with the default constructor." );

Evidence ev1 = new Evidence();
Console.WriteLine("Created empty evidence with the default constructor.");
Dim ev1 As New Evidence
Console.WriteLine("Created empty evidence with the default constructor.")

Evidence(Evidence)

Initializes a new instance of the Evidence class from a shallow copy of an existing one.

public:
 Evidence(System::Security::Policy::Evidence ^ evidence);
public Evidence (System.Security.Policy.Evidence evidence);
new System.Security.Policy.Evidence : System.Security.Policy.Evidence -> System.Security.Policy.Evidence
Public Sub New (evidence As Evidence)

Parameters

evidence
Evidence

The Evidence instance from which to create the new instance. This instance is not deep-copied.

Exceptions

The evidence parameter is not a valid instance of Evidence.

Examples

The following code example shows the use of the Evidence(Evidence) constructor. This example is part of a larger example provided for the Evidence class.

Console::WriteLine( "\nMake a copy of the current evidence." );
Evidence^ evidenceCopy = gcnew Evidence( myEvidence );
Console::WriteLine( "Count of new evidence items = {0}", evidenceCopy->Count );
Console::WriteLine( "Does the copy equal the current evidence? {0}", myEvidence->Equals( evidenceCopy ) );
Console.WriteLine("\nMake a copy of the current evidence.");
Evidence evidenceCopy = new Evidence(myEvidence);
Console.WriteLine("Count of new evidence items = " + evidenceCopy.Count);
Console.WriteLine("Does the copy equal the current evidence? " + myEvidence.Equals(evidenceCopy));
Console.WriteLine(ControlChars.Lf & "Make a copy of the current evidence.")
Dim evidenceCopy As New Evidence(myEvidence)
Console.WriteLine(("Count of new evidence items = " & evidenceCopy.Count.ToString()))
Console.WriteLine(("Does the copy equal the current evidence? " & myEvidence.Equals(evidenceCopy)))

Evidence(Object[], Object[])

Warning

This API is now obsolete.

Initializes a new instance of the Evidence class from multiple sets of host and assembly evidence.

public:
 Evidence(cli::array <System::Object ^> ^ hostEvidence, cli::array <System::Object ^> ^ assemblyEvidence);
[System.Obsolete]
public Evidence (object[] hostEvidence, object[] assemblyEvidence);
public Evidence (object[] hostEvidence, object[] assemblyEvidence);
[System.Obsolete("This constructor is obsolete. Please use the constructor which takes arrays of EvidenceBase instead.")]
public Evidence (object[] hostEvidence, object[] assemblyEvidence);
new System.Security.Policy.Evidence : obj[] * obj[] -> System.Security.Policy.Evidence
Public Sub New (hostEvidence As Object(), assemblyEvidence As Object())

Parameters

hostEvidence
Object[]

The host evidence from which to create the new instance.

assemblyEvidence
Object[]

The assembly evidence from which to create the new instance.

Attributes

Examples

The following code example shows the use of the Evidence(Object[], Object[]) constructor. This example is part of a larger example provided for the Evidence class.

array<Object^>^oa1 = {};
Site^ site = gcnew Site( "www.wideworldimporters.com" );
array<Object^>^oa2 = {url,site};
Evidence^ ev3a = gcnew Evidence( oa1,oa2 );
enum1 = ev3a->GetHostEnumerator();
IEnumerator^ enum2 = ev3a->GetAssemblyEnumerator();
enum2->MoveNext();
Object^ obj1 = enum2->Current;
enum2->MoveNext();
Console::WriteLine( "URL = {0}  Site = {1}", obj1, enum2->Current );

Object [] oa1 = {};
Site site = new Site("www.wideworldimporters.com");
Object [] oa2 = { url, site };
Evidence ev3a = new Evidence(oa1, oa2);
enum1 = ev3a.GetHostEnumerator();
IEnumerator enum2 = ev3a.GetAssemblyEnumerator();
enum2.MoveNext();
Object obj1 = enum2.Current;
enum2.MoveNext();
Console.WriteLine("URL = " + obj1.ToString() + "  Site = " + enum2.Current.ToString());
Dim oa1() As [Object]
Dim site As New Site("www.wideworldimporters.com")
Dim oa2 As [Object]() = {url, site}
Dim ev3a As New Evidence(oa1, oa2)
enum1 = ev3a.GetHostEnumerator()
Dim enum2 As IEnumerator = ev3a.GetAssemblyEnumerator()
enum2.MoveNext()
Dim obj1 As [Object] = enum2.Current
enum2.MoveNext()
Console.WriteLine(("URL = " & obj1.ToString() & "  Site = " & enum2.Current.ToString()))

Evidence(EvidenceBase[], EvidenceBase[])

Initializes a new instance of the Evidence class from multiple sets of host and assembly evidence.

public:
 Evidence(cli::array <System::Security::Policy::EvidenceBase ^> ^ hostEvidence, cli::array <System::Security::Policy::EvidenceBase ^> ^ assemblyEvidence);
public Evidence (System.Security.Policy.EvidenceBase[] hostEvidence, System.Security.Policy.EvidenceBase[] assemblyEvidence);
new System.Security.Policy.Evidence : System.Security.Policy.EvidenceBase[] * System.Security.Policy.EvidenceBase[] -> System.Security.Policy.Evidence
Public Sub New (hostEvidence As EvidenceBase(), assemblyEvidence As EvidenceBase())

Parameters

hostEvidence
EvidenceBase[]

The host evidence from which to create the new instance.

assemblyEvidence
EvidenceBase[]

The assembly evidence from which to create the new instance.

Remarks

This constructor creates a new instance of the class by using evidence objects that inherit from the EvidenceBase class.
