var msg= client.GetMessage(uid,true,Conf.ConfigInfo.SelectFolder);

注：默认MSG 是获取的TEXT 邮件内容要获取HTML内容代码如下

var dataStream = msg.AlternateViews[0].ContentStream; byte[] byteBuffer = new byte[dataStream.Length]; string altbody = msg.BodyEncoding.GetString(byteBuffer, 0, dataStream.Read(byteBuffer, 0, byteBuffer.Length));
