推荐答案

由于问题是关于MFC的，我建议如下:

As the question is about MFC, I would suggest the following:

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

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 和 CStringA 分别有运算符 LPCWSTR 和 LPCSTR.

CStringW and CStringA have operators LPCWSTR and LPCSTR respectivelly.
