c ++自动'类型转换'转换

有人可以解释为什么下面的代码不能在错误时编译:

Error   1   error C2243: 'type cast' : conversion from 'Der *' to 'Base *' exists, but is inaccessible  d:\users\lzizva\documents\mta\c++\projects\temp1\17022014.cpp   50  1   temp1
Error   2   error C2243: 'type cast' : conversion from 'Der *' to 'Base *' exists, but is inaccessible  d:\users\lzizva\documents\mta\c++\projects\temp1\17022014.cpp   51  1   temp1

我认为当有私有继承时,子进程获取所有属性和方法并将它们设置为私有,它只会影响子进程的子类.我在这里错过了什么？编译器实际上做了什么？
