Question

C# 从System.IO.Stream保存文件

我是这样写的：
private void WriteFile(System.IO.Stream stream, string filename)
{
using (System.IO.StreamWriter objwrite = new System.IO.StreamWriter(filename))
{
int k = 0;
while (k != -1)
{
k = stream.ReadByte();
if (k != -1)
{
objwrite.BaseStream.WriteByte((byte)k);
}
}
}
}

但是保存起来极费时间。请问有没有更好的方法？

StreamWriter sw = new StreamWriter(filename);
stream.CopyTo(sw.BaseStream);
sw.Flush();
sw.Close();
