1、char * 转成 CString

char *str="abcd1234";
//预转换，得到所需空间的大小
int wcsLen = ::MultiByteToWideChar(CP_ACP, NULL, inputbuffer, strlen(inputbuffer), NULL, 0);
//分配空间要给'\0'留个空间，MultiByteToWideChar不会给'\0'空间
wchar_t* wszString = new wchar_t[wcsLen + 1];
//转换
::MultiByteToWideChar(CP_ACP, NULL, inputbuffer, strlen(inputbuffer), wszString, wcsLen);
//最后加上'\0'
wszString[wcsLen] = '\0';
//附加到CString对象上
CString content;
content.Append(wszString);

1、CString 转成 char *

CString str=_T("hello kitty 12345 hello jackson");
int len=str.GetLength();
    
char *buffer=new char[len+1];
memset(buffer,0,len+1);

WideCharToMultiByte(CP_OEMCP, NULL, (LPCWSTR)str, -1,NULL, 0, NULL, FALSE);
WideCharToMultiByte(CP_OEMCP, NULL, (LPCWSTR)str, -1,(LPSTR)buffer, len, NULL, FALSE);
    
buffer[len]='\0';
