请问:sapop3读出来的邮件为乱码，该如何解决呢？？

都用utf-8进行编码和显示

可能跟以下函数有关，不知得如何改？

private void GetEncoding()
{
int begin, end;
begin = end = 0;

try
{
if((begin = m_strLowHeader.IndexOf("content-transfer-encoding: ")) < 0)
throw new POP3ParseException("could not find Encoding tag");
if((end = m_strHeader.Substring(begin).IndexOf("\r\n")) < 0)
throw new POP3ParseException("could not find end of Encoding tag");

end += begin;
begin += 27;
m_strEncoding = m_strHeader.Substring(begin, end - begin).ToLower();

}
catch(POP3ParseException e)
{
m_pSAPOP3.TRACE(e.ToString());
if(m_pSAPOP3.Log)
{
string strErr = "SAPOP3Message::GetUID()";
strErr += e.Message;
m_pSAPOP3.TRACE(strErr);
}
}
catch(Exception e)
{
m_pSAPOP3.TRACE(e.ToString());
if(m_pSAPOP3.Log)
{
string strErr = "SAPOP3Message::GetUID()";
strErr += e.Message;
m_pSAPOP3.LogError(strErr);
}
}

}
protected void GetCharSet()
{
int begin, end;
begin = end = 0;
try
{
// parse buffer
if((begin = m_strLowHeader.IndexOf("charset=")) < 0)
throw new POP3ParseException ("GetCharSet could not find beginning of 'charset' tag");
if((end = m_strHeader.Substring(begin + 2).IndexOf("\"")) < 0)
throw new POP3ParseException ("GetCharSet could not find end of 'charset' tag");

// make temporary string of charset tag
string strContType = m_strHeader.Substring(begin);

// parse mime version
if((begin = strContType.IndexOf("\"")) < 0)
throw new POP3ParseException ("GetCharSet could not find leading ' '");
if((end = strContType.LastIndexOf("\"")) < 0)
throw new POP3ParseException("GetCharSet could not fine end of tag");


m_strCharset = strContType.Substring(++begin, end - begin).ToLower();
}
catch(POP3ParseException e)
{
m_pSAPOP3.TRACE(e.ToString());
if(m_pSAPOP3.Log)
{
string strErr = "SAPOP3Message::GetUID()";
strErr += e.Message;
m_pSAPOP3.TRACE(strErr);
}
}
catch(Exception e)

if(m_pSAPOP3.Log)
{

具体得如何改呢？？
