C++ 类型转换

CString -> cv::String USES_CONVERSION; CString str = "abcdefg"; cv::String cvStr = W2A(str);

2.cv::String -> CString

USES_CONVERSION; cv::String b = "abcdefg; std::string c = b; CString a = A2W(c.c_str());

3.CString->const char*

USES_CONVERSION; CString str = "abcdefg"; const char* c = T2A(str);

4.const char*->CString

USES_CONVERSION; const char* c="dfasefe"; CString cstr = A2T(c);
