MFC中的CString转char*

void CSocketClient3Dlg::OnBnClickedButtonSendmsg()
{

CString strText;
GetDlgItemText(IDC_EDIT_MSG, strText); //从文本框获得文本
char *str=(LPSTR)(LPCTSTR)strText; //CString转为Char*
TCP_PACKAGE tcpPackage; //定义数据包格式
memset(&tcpPackage,0,sizeof(TCP_PACKAGE)); //初始化数据包
tcpPackage.cmdType=CT_TEXT; //命令为文本数据

strncpy(tcpPackage.chText,"你好吗！",512);

m_ClientSock.Send(&tcpPackage,sizeof(TCP_PACKAGE));

SetDlgItemText(IDC_EDIT_MSG, _T("")); // 将文本框清空，以便继续输入

}

要CString转换后达到 "你好吗！"一样的效果

该怎么转？

最简单的就是好漏把项目改成多字节字符集，如信CString就等于const char*，如果需要char*就GetBuffer，用完再ReleaseBuffer或是复制一份渣袜轮．

char * cs2ca(CString str)
{
char *ptr;
#ifdef _UNICODE
LONG len;
len = WideCharToMultiByte(CP_ACP, 0, str, -1, NULL, 0, NULL, NULL);
ptr = new char [len+1];
memset(ptr,0,len + 1);
WideCharToMultiByte(CP_ACP, 0, str, -1, ptr, len + 1, NULL, NULL);
#else
ptr = new char [str.GetAllocLength()+1];
sprintf(ptr,_T("%s"),str);
#endif
return ptr;
}
CString转char*的最槐前脊佳悔老方案铅渗

---

strncpy(tcpPackage.chText, strText.GetBuffer(), 512);
//告桐磨高用完后再调用袜游坦：
strText.ReleaseBuffer();

---

strcpy(tcpPackage.chText, strText )
