UNICODE下CString转string

真搞不懂，为毛C++这么多类型转换。。

CString m_str(_T("fuck conversion"));

char *chr=new char[m_str.GetLength()+1];
WideCharToMultiByte(CP_ACP,0,m_str.GetBuffer(),-1,chr,m_str.GetLength()+1,NULL,NULL);
string str=chr;

cout<<str;

2、char转string

char ch[10] = {0};

itoa(i, ch, 10);

std::string str = (char *)ch;

3、int转byte

public byte[] intToByte(int i) {
byte[] abyte0 = new byte[4];
abyte0[0] = (byte) (0xff & i);
abyte0[1] = (byte) ((0xff00 & i) >> 8);
abyte0[2] = (byte) ((0xff0000 & i) >> 16);
abyte0[3] = (byte) ((0xff000000 & i) >> 24);
return abyte0;
}
4、byte转int
public static int bytesToInt(byte[] bytes) {
int addr = bytes[0] & 0xFF;
addr |= ((bytes[1] << 8) & 0xFF00);
addr |= ((bytes[2] << 16) & 0xFF0000);
addr |= ((bytes[3] << 24) & 0xFF000000);
return addr;
}
