现在你可以使用getKeyByValue方法来获取键值了。下面是一个使用示例: publicclassMain{publicstaticvoidmain(String[]args){MyEnummyEnum=MyEnum.getKeyByValue("Value2");if(myEnum!=null){System.out.println("Key: "+myEnum.name()+", Value: "+myEnum.getValue());}else{System.out.println("Key not...
Text += i.ToString(); 5、枚举所有的名称 foreach ( string temp in Enum.GetNames( typeof (TimeOfDay))) lbNames.Text += temp; 枚举和常量 优先考虑枚举。 在C#中,枚举的真正强大之处是它们在后台会实例化为派生于基类System.Enum的结构。这表示可以对它们调用方法,执行有用的任务。注意因为.NET ...
