示例

// cliext_pair_swap.cpp 
// compile with: /clr 
#include <cliext/adapter> 
#include <cliext/deque> 
 
typedef cliext::collection_adapter< 
    System::Collections::ICollection> Mycoll; 
int main() 
    { 
    cliext::deque<wchar_t> d1; 
    d1.push_back(L'a'); 
    d1.push_back(L'b'); 
    d1.push_back(L'c'); 
    Mycoll c1(%d1); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// construct another container with repetition of values 
    cliext::deque<wchar_t> d2(5, L'x'); 
    Mycoll c2(%d2); 
    for each (wchar_t elem in c2) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// swap and redisplay 
    c1.swap(c2); 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
    for each (wchar_t elem in c2) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
