.net 中用Obsolete属性,每次使用被标记为已过时的实体时,随后将生成警告或错误,这取决于属性是如何配置的。
c#:
[System.Obsolete("use class B")] class A { public void Method() { } } class B { [System.Obsolete("use NewMethod",true)] public void OldMethod() { } public void NewMethod() { } } // Generates 2 warnings: A a = new A(); // Generate no errors or warnings: B b = new B(); b.NewMethod(); // Generates an error,terminating compilation: b.OldMethod();
为类 A 产生两个警告:一个用于声明类引用,一个用于类构造函数。
vb.net:
<System.Obsolete("use class B")> Class A Sub Method() End Sub End Class Class B <System.Obsolete("use NewMethod",True)> Sub OldMethod() End Sub Sub NewMethod() End Sub End Class ' Generates 2 warnings: ' Dim a As New A ' Generate no errors or warnings: Dim b As New B b.NewMethod() ' Generates an error,terminating compilation: ' b.OldMethod()
java中使用@Deprecated注解,标记已过时.
@Deprecated public void showTaste(){ System.out.println("水果的苹果的口感是:脆甜"); }原文链接:https://www.f2er.com/vb/258926.html
