operator== (list) (STL/CLR)

發行項

列出相等比較。

template<typename Value>
    bool operator==(list<Value>% left,
        list<Value>% right);

參數

left
要比較的左邊容器。
right
要比較的右邊容器。

備註

只有當順序是由 left 和 right 具有相同的長度，而且對於每個位置的 i來說，left[i] == right[i]時，運算子函式才會傳回 true。您會用它來測試在這兩個清單是項目對項目的比較時， left 是否與 right 排序相同。

範例

// cliext_list_operator_eq.cpp 
// compile with: /clr 
#include <cliext/list> 
 
int main() 
    { 
    cliext::list<wchar_t> c1; 
    c1.push_back(L'a'); 
    c1.push_back(L'b'); 
    c1.push_back(L'c'); 
 
// display contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// assign to a new container 
    cliext::list<wchar_t> c2; 
    c2.push_back(L'a'); 
    c2.push_back(L'b'); 
    c2.push_back(L'd'); 
 
// display contents " a b d" 
    for each (wchar_t elem in c2) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
    System::Console::WriteLine("[a b c] == [a b c] is {0}", 
        c1 == c1); 
    System::Console::WriteLine("[a b c] == [a b d] is {0}", 
        c1 == c2); 
    return (0); 
    }
