初始化 Evidence 类的新实例。

重载

Evidence()	初始化 Evidence 类的新的空实例。
Evidence(Evidence)	从现有证据的浅表副本初始化 Evidence 类的新实例。
Evidence(Object[], Object[])	已过时。已过时。已过时。依据多个主机和程序集证据集初始化 Evidence 类的新实例。
Evidence(EvidenceBase[], EvidenceBase[])	依据多个主机和程序集证据集初始化 Evidence 类的新实例。

Evidence()

初始化 Evidence 类的新的空实例。

public:
 Evidence();

public Evidence ();

Public Sub New ()

示例

下面的代码示例演示了 Evidence() 构造函数的使用。此示例是为类提供的大型示例的 Evidence 一部分。

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.")

适用于

Evidence(Evidence)

从现有证据的浅表副本初始化 Evidence 类的新实例。

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)

参数

evidence: Evidence

从其创建新实例的 Evidence 实例。此实例不是深层复制的。

例外

ArgumentException

evidence 参数不是 Evidence 的有效实例。

示例

下面的代码示例演示了 Evidence(Evidence) 构造函数的使用。此示例是为类提供的大型示例的 Evidence 一部分。

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)))

适用于

Evidence(Object[], Object[])

public Evidence (object[] hostEvidence, object[] assemblyEvidence);

public Evidence (object[] hostEvidence, object[] assemblyEvidence);

new System.Security.Policy.Evidence : obj[] * obj[] -> System.Security.Policy.Evidence

new System.Security.Policy.Evidence : obj[] * obj[] -> System.Security.Policy.Evidence

Public Sub New (hostEvidence As Object(), assemblyEvidence As Object())

参数

hostEvidence: Object[]

创建新实例所依据的主机证据。

assemblyEvidence: Object[]

创建新实例所依据的程序集证据。

属性: ObsoleteAttribute

示例

下面的代码示例演示了 Evidence(Object[], Object[]) 构造函数的使用。此示例是为类提供的大型示例的 Evidence 一部分。

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()))
