示例
下面的代码示例演示 Count 属性的用法。此示例摘自为 Evidence 类提供的一个更大的示例。
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)))
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( "\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.get_Count()));
Console.WriteLine(("Does the copy equal the current evidence? "
+ System.Convert.ToString(myEvidence.Equals(evidenceCopy))));
