Question

我想以编程方式将大文件复制到同一网络中的多个服务器中。文件大小从500MB到1GB不等。

我已经使用WCF实现了逻辑，但是将文件复制到一台服务器需要30分钟以上，因此需要一些时间才能复制到多台服务器上。如果有人想到更好的方法来实现这一目标，我将不胜感激。

现在，我正在考虑断开用户并使用C＃windows服务（和WCF）在后台复制文件，并在复制过程完成后通知用户。有什么想法吗？

下面提到的代码：

[MessageContract]
public class FileCopyRequest : IDisposable
{
    [MessageHeader(MustUnderstand = true)]
    public string FileName { get; set; }

    [MessageHeader(MustUnderstand = true)]
    public string[] DestinationFilePaths { get; set; }

    [MessageBodyMember(Order = 1)]
    public Stream FileContent { get; set; }

    public void Dispose()
    {
        if (FileContent != null)
        {
            FileContent.Close();
            FileContent = null;
        }
    }
}

public class FileCopyService : IFileCopyService
{
    public void CopyFile(FileCopyRequest request)
    {

       foreach(var destinationPath in request.DestinationFilePaths)
       {
            var buffer = new byte[65000];
            int read;

            using (var destinationStream = new FileStream(destinationPath, FileMode.Create))
            {
                while ((read = request.FileContent.Read(buffer, 0, buffer.Length)) > 0)
                {
                    destinationStream.Write(buffer, 0, read);
                }
            }
        }

    }
}
