The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at operator== (list) (STL/CLR).

List equal comparison.

Syntax

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

Parameters

left
Left container to compare.

right
Right container to compare.

Remarks

The operator function returns true only if the sequences controlled by left and right have the same length and, for each position i, left``[i] == right``[i]. You use it to test whether left is ordered the same as right when the two lists are compared element by element.

Example

// 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);   
    }

 a b c  
 a b d  
[a b c] == [a b c] is True  
[a b c] == [a b d] is False
