hash_set::find (STL/CLR)

Finds an element that matches a specified key.

    iterator find(key_type key);


Key value to search for.

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 hash_set::end (STL/CLR)(). You use it to locate an element currently in the controlled sequence that matches a specified key.

// cliext_hash_set_find.cpp 
// compile with: /clr 
#include <cliext/hash_set> 
typedef cliext::hash_set<wchar_t> Myhash_set; 
int main() 
    Myhash_set c1; 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    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); 
a b c find A = False find b = b find C = False

Note that find does not guarantee which of several element it finds.
