sw.Write(sr0.ReadToEnd());
}



//在讀取該文件,返回一個Stream.
StreamReader sr1 = new StreamReader(strpatj + "\\temp\\" + "temp.csv", System.Text.Encoding.GetEncoding("gb2312")); //讀取這個流

//未測試
using (FileStream fsw = new FileStream(strpatj + "\\temp\\" + "temp.csv", FileMode.Create, FileAccess.Write))  //打開文件，用於只寫??
{
BinaryWriter bw = new BinaryWriter(fsw); //編寫器指向這個文件流??
bw.Write(System.IO.File.ReadAllBytes(strpatj + "\\temp\\" + "temp.csv"));    //打開一個文件讀取流信息，將其寫入新文件??
System.IO.File.Delete(path + i.ToString() + "_" + filename);        //刪除指定文件信息??
bw.Flush(); //清理緩沖區??
