Recherche un élément qui correspond à une clé spécifiée.

    iterator find(key_type key);

Paramètres

key
Key value to search for.

Notes

If at least one element in the controlled sequence has equivalent ordering with key, the member function returns an iterator designating one of those elements; otherwise it returns définissez : : fin (STL/CLR)(). You use it to locate an element currently in the controlled sequence that matches a specified key.

Exemple

// cliext_set_find.cpp 
// compile with: /clr 
#include <cliext/set> 
 
typedef cliext::set<wchar_t> Myset; 
int main() 
    { 
    Myset c1; 
    c1.insert(L'a'); 
    c1.insert(L'b'); 
    c1.insert(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
    System::Console::WriteLine("find {0} = {1}", 
        L'A', c1.find(L'A') != c1.end()); 
    System::Console::WriteLine("find {0} = {1}", 
        L'b', *c1.find(L'b')); 
    System::Console::WriteLine("find {0} = {1}", 
        L'C', c1.find(L'C') != c1.end()); 
    return (0); 
    }
