operator== (pair) (STL/CLR)

發行項

對相等比較。

template<typename Value1,
    typename Value2>
    bool operator==(pair<Value1, Value2>% left,
        pair<Value1, Value2>% right);

參數

left
要比較的左邊。
right
要比較的物件。

備註

運算子函式會傳回 left.first == right.first && left.second == right.second。您會用它來測試在這兩對是項目對項目的比較時， left 是否與 right 排序相同。

範例

// cliext_pair_operator_eq.cpp 
// compile with: /clr 
#include <cliext/utility> 
 
int main() 
    { 
    cliext::pair<wchar_t, int> c1(L'x', 3); 
    System::Console::WriteLine("[{0}, {1}]", c1.first, c1.second); 
    cliext::pair<wchar_t, int> c2(L'x', 4); 
    System::Console::WriteLine("[{0}, {1}]", c2.first, c2.second); 
 
    System::Console::WriteLine("[x 3] == [x 3] is {0}", 
        c1 == c1); 
    System::Console::WriteLine("[x 3] == [x 4] is {0}", 
        c1 == c2); 
    return (0); 
    }
