示例
下面的示例显示 GetHostEnumerator 方法的用法。此示例摘自为 Evidence 类提供的一个更大的示例。
Dim url As New Url("http://www.treyresearch.com")
Console.WriteLine(("Adding host evidence " & url.ToString()))
ev2a.AddHost(url)
Dim ev2b As New Evidence(ev2a)
Console.WriteLine("Copy evidence into new evidence")
Dim enum1 As IEnumerator = ev2b.GetHostEnumerator()
enum1.MoveNext()
Console.WriteLine(enum1.Current.ToString())
Url url = new Url("http://www.treyresearch.com");
Console.WriteLine("Adding host evidence " + url.ToString());
ev2a.AddHost(url);
Evidence ev2b = new Evidence(ev2a);
Console.WriteLine("Copy evidence into new evidence");
IEnumerator enum1 = ev2b.GetHostEnumerator();
enum1.MoveNext();
Console.WriteLine(enum1.Current.ToString());
Url^ url = gcnew Url( "http://www.treyresearch.com" );
Console::WriteLine( "Adding host evidence {0}", url );
ev2a->AddHost( url );
Evidence^ ev2b = gcnew Evidence( ev2a );
Console::WriteLine( "Copy evidence into new evidence" );
IEnumerator^ enum1 = ev2b->GetHostEnumerator();
enum1->MoveNext();
Console::WriteLine( enum1->Current );
Url url = new Url("http://www.treyresearch.com");
Console.WriteLine(("Adding host evidence " + url.ToString()));
ev2a.AddHost(url);
Evidence ev2b = new Evidence(ev2a);
Console.WriteLine("Copy evidence into new evidence");
IEnumerator enum1 = ev2b.GetHostEnumerator();
enum1.MoveNext();
Console.WriteLine(enum1.get_Current().ToString());
