C#文件斷點續傳完成辦法。本站提示廣大學習愛好者：（C#文件斷點續傳完成辦法）文章只能為提供參考，不一定能成為您想要的結果。以下是C#文件斷點續傳完成辦法正文

本文實例講述了C#文件斷點續傳完成辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

 int allBytesCount = 0;
 //每次傳輸年夜小

 //以後地位

 //剩下年夜小
 int remain = 0;

  while (remain > 0)
  {
   fileStream.Write(bytes, bytePosition, byteTemp);
   remain = remain - byteTemp;
   bytePosition = bytePosition + byteTemp;
   fileStream.Flush();
   if (remain < byteTemp)
    byteTemp = remain;
  }
  Console.WriteLine("下載勝利!");
 }
 catch (Exception ex)
 {
  Console.WriteLine(ex.Message);
 }
 finally
 {
  fileStream.Close();
  fileStream.Dispose();
  stream.Close();
  stream.Dispose();
 }
}
