If you need to convert a Standard C++ string to a null-terminated C-style string, use the basic_string::c_str member. Syntax C++ Copy template <class CharType, class Traits = char_traits<CharType>, class Allocator = allocator<CharType>> class basic_string; Parameters CharType The ...
以下示例演示了CType的用法。 VB k =CType(q,Integer)' The following statement coerces w to the specific object class Label.f =CType(w, Label) 复合类型 你可以使用CType将值转换为复合数据类型以及基本类型。 还可以使用它将对象类强制转换为其接口之一的类型,如以下示例所示。
