Evidence Constructors

Definition

Namespace:

System.Security.Policy

Assembly:

System.Security.AccessControl.dll

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[])	Obsolete. 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.

C#

public Evidence();

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.

C#

Evidence ev1 = 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.

C#

public Evidence(System.Security.Policy.Evidence evidence);

Parameters

evidence

Evidence

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

Exceptions

ArgumentException

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.

C#

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));

Evidence(Object[], Object[])

Caution

This constructor is obsolete. Use the constructor which accepts arrays of EvidenceBase instead.

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

C#

[System.Obsolete("This constructor is obsolete. Use the constructor which accepts arrays of EvidenceBase instead.")]
public Evidence(object[] hostEvidence, object[] assemblyEvidence);

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

ObsoleteAttribute

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.

C#

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());

Evidence(EvidenceBase[], EvidenceBase[])

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

C#

public Evidence(System.Security.Policy.EvidenceBase[] hostEvidence, System.Security.Policy.EvidenceBase[] assemblyEvidence);

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.
