using static

C#引用命名空间,一般用using,那么usingstatic是什么东西呢?usingstatic除了命名空间,还可以在命名空间最后加一个类,这样后面可以直接使用这个类的:静态方法、类中类等。比如,以类中类来举例,原来是:usingItpow;Class1.Class2c=newClass1.Class2();现在可以...

派生类与基类的 static 共享

classB{publicstaticstringP="abc";}classD:B{publicD(){P="123";}}MessageBox.Show(B.P);newD();MessageBox.Show(B.P);显示结果是abc、123,因为newD()时,通过构造函数改变P的值,而static变量在派生类...

const 字段与 static const 字段

应该说,只有const字段,没有staticconst字段。const字段是恒定不变的,所以它本来就是static的,不能再加static,加了不仅画蛇添足,反而出错。privateconststring_str1="111";//privatestaticconststring_str2="222"; //...
