如何将LPCSTR字符串转换为LPCTSTR字符串？

问题描述：

我试图将 LPCSTR 字符串转换为 LPCTSTR 字符串。我想连接两个字符串，当我尝试这样

i am trying to convert a LPCSTR string into LPCTSTR string. i want to concatenate two string,when i try like this

LPCTSTR str1 = L"Raja"
LPCSTR str2 = "Kumar"
wcscat_s(str1,(LPCTSTR)str2);

我发现o / p像Raja .... r（junkvalues）.... how可以typecast LPCSTR 到 LPCTSTR ？

i found the o/p like Raja....r(junkvalues)....how can typecast LPCSTR to LPCTSTR?

答

LPCTSTR 可以是纯字符或宽字符，具体取决于项目设置。此外，你不能连接一个宽字符串和一个纯char字符串。您需要将一个转换为兼容的形式（宽到多字节，反之亦然），然后连接。

LPCTSTR can be either plain char or wide characters depending on your project settings. Further, you cannot possibly concatenate a wide string and a plain char string. You need to convert one to a compatible form (wide to multibyte or vice versa) and then concatenate.

假设您希望目标是一个宽字符串，需要将Kumar转换为宽字符串。为此，请使用 MultiByteToWideChar 功能。

Assuming you want the target to be a wide string, you'd need to convert the "Kumar" to a wide character string. To do this use the MultiByteToWideChar function with appropriate code page.
