operator== (list) (STL/CLR)

2015-06-09

列出相等比较。

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

参数

left
比较左边的容器。
right
比较右边的容器。

备注

当由 left 和 right 控制的顺序具有相同长度，并且，对每个位置 i，left[i] == right[i]，该运算符函数返回 true。当一个个元素地比较两个对列表时，您可以用它测试 left 是否在 right 之后排序。

示例

// 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); 
    }
