Answer 1

As the question is about MFC, I would suggest the following: 由于问题是关于MFC，我建议如下：

CStringA a = "Test";
CStringW w = L"Test";
a = CStringA(w);
w = CStringW(a);

I typically need the following conversions: 我通常需要以下转换：

CString t = _T("Test"); // depends on TCHAR type
a = CStringA(t); // does not depend on TCHAR type
w = CStringW(t);

CStringW and CStringA have operators LPCWSTR and LPCSTR respectivelly. CStringW和CStringA分别具有运算符LPCWSTR和LPCSTR。
