数组问题

Question

System.Text.Encoding.GetEncoding("gb2312").GetString(by,0,ms.Length);

Answer 1

或者在read前面加一句
ms.Position = 0;

Answer 2

MemoryStream ms=new MemoryStream();
XmlTextWriter tw=new XmlTextWriter(ms,null);
tw.Formatting=Formatting.Indented;
tw.WriteStartDocument();
tw.WriteStartElement("a");
for(int i=0;i<2;i++)
{
tw.WriteStartElement("Formula");
tw.WriteEndElement();
}
tw.WriteEndElement();
tw.WriteEndDocument();
tw.Flush();ms.Position = 0;
byte[] by = new byte[ms.Length];
ms.Read(by,0,Convert.ToInt32(ms.Length));
Console.WriteLine(Encoding.Default.GetString(by));Console.ReadLine();
