如果是未找到类型，检查是否引用了类型所在的命名空间，使用using指令。如果是未找到命名空间，那么检查是否引用了程序集，如果确认引用了程序集，那么检查程序集版本和项目是否一致。例如，项目是.net 4.0，而程序集是.net 3.5下编译的，或者引用项目与被引用项目的.NET framework版本不一样，例如一个是...
有如下程序: #include<iostream> using namespace std; class XX{ protected; int k; public: XX(int n=5):k(n){} ～XX(){cout<<"XX";} virtual void f()const=0; }; inline void XX::f()const{cout<<k+3;} class YY:public XX{ public: ～YY(){cout<<"YY";} void f()const{out<...
class Foo { static void Bar() { double d = Math.PI; } }} 这也说明了一点,程序总总是先看自己同一命名空间中的定义,其次再看同一命名空间中的 using 语句,如果都没找到再去外层命名空间中按照同样的顺序查找。 正如这篇讨论提到的,Should ‘using’ statements be inside or outside the namespace,在...
程序中丢了许多必要的空格。
