The latest version of this topic can be found at set::find (STL/CLR).

Finds an element that matches a specified key.

Syntax

iterator find(key_type key);

Parameters

key
Key value to search for.

Remarks

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

Example

// 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);   
    }

 a b c  
find A = False  
find b = b  
find C = False
