远程处理中的文件传输

我是 .net 远程处理的新手，我在 .net 远程处理上做了一些示例应用程序。我可以轻松地通过远程对象从服务器获取文件，但我不知道如何将文件发送到服务器端，如果可以通过接口意味着如何设计它。给我一些建议和链接，这对我很有用朝正确的方向行驶

要发送文件，您可以重复调用服务器上的方法以逐块向其提供文件。像这样：

static int CHUNK_SIZE = 4096;

// open the file
FileStream stream = File.OpenRead("path\to\file");

// send by chunks
byte[] data = new byte[CHUNK_SIZE];
int numBytesRead = CHUNK_SIZE;
while ((numBytesRead = stream.Read(data, 0, CHUNK_SIZE)) > 0)
{
    // resize the array if we read less than requested
    if (numBytesRead < CHUNK_SIZE)
        Array.Resize(data, numBytesRead);

    // pass the chunk to the server
    server.GiveNextChunk(data);
    // re-init the array so it's back to the original size and cleared out.
    data = new byte[CHUNK_SIZE];
}

// an example of how to let the server know the file is done so it can close
// the receiving stream on its end.
server.GiveNextChunk(null);

// close our stream too
stream.Close();

To send a file, you could repeatedly call a method on the server to give it the file chunk by chunk. Like this:

static int CHUNK_SIZE = 4096;

// open the file
FileStream stream = File.OpenRead("path\to\file");

// send by chunks
byte[] data = new byte[CHUNK_SIZE];
int numBytesRead = CHUNK_SIZE;
while ((numBytesRead = stream.Read(data, 0, CHUNK_SIZE)) > 0)
{
    // resize the array if we read less than requested
    if (numBytesRead < CHUNK_SIZE)
        Array.Resize(data, numBytesRead);

    // pass the chunk to the server
    server.GiveNextChunk(data);
    // re-init the array so it's back to the original size and cleared out.
    data = new byte[CHUNK_SIZE];
}

// an example of how to let the server know the file is done so it can close
// the receiving stream on its end.
server.GiveNextChunk(null);

// close our stream too
stream.Close();
