本打算”偷”Yahoo的,但后来还是爱上sohu的了
立马就放了上来
大家可以看看效果
获取yahoo的天气预报信息

.net中实现繁简互换

重写了Stream类
本站就是这样实现的
需要引入Microsoft.VisualBasic;
class CnToTwStream : Stream
{
private Stream _sink;
private MemoryStream _ms;
private Encoding _encoding;</code>
public CnToTwStream(Stream sink, Encoding encoding)
{
_sink = sink;
_ms = new MemoryStream();
_encoding = encoding;
}
public override bool CanRead
{
get { return false; }
}
public override bool CanSeek
{
get { return false; }
}
public override bool CanWrite
{
get { return true; }
}
public override long Length
{
get { return _ms.Length; }
}
public override long Position
{
get { return _ms.Position; }
set { throw new NotSupportedException(); }
}
public override int Read(byte[] buffer, int offset, int count)
{
throw new NotSupportedException();
}
public override long Seek(long offset, System.IO.SeekOrigin direction)
{
throw new NotSupportedException();
}
public override void SetLength(long length)
{
throw new NotSupportedException();
}
public override void Close()
{
_ms.Close();
byte[] buffer_cn = _ms.GetBuffer();
string str_cn = _encoding.GetString(buffer_cn);
string str_tw = Strings.StrConv(str_cn, VbStrConv.TraditionalChinese, 0);
byte[] buffer_tw = _encoding.GetBytes(str_tw);
using (_sink)
{
_sink.Write(buffer_tw, 0, buffer_tw.Length);
}
}
public override void Flush()
{
_ms.Flush();
}
public override void Write(byte[] buffer, int offset, int count)
{
_ms.Write(buffer, offset, count);
}
}
