大家好，

我正在编写一个asp.net 4.0 Web应用程序.http://server/webscan/
我的应用程序使用activex控件进行扫描和图像处理，然后保存到本地磁盘c:\ temp.pdf.

推荐答案

如果您可以访问activex控件中的代码，我建议您研究一下在其中放置一些推送到服务器"的代码.这样，您可以执行操作而无需用户做任何额外的事情.我还建议您创建一个Web服务，以供ActiveX控件使用以传输文件.

要通过Web服务接收大量数据，请参见: http://msdn.microsoft. com/en-us/library/aa528822.aspx [ ^ ]

If you have access to the code in the activex control, I would suggest to investigate putting some "push to server" code in there. That way you could perform the action without requiring the user to do anything extra. I would also suggest that you create a web service for the activeX control to consume in order to transfer the file.

To receive large amounts of data through a web service see this: http://msdn.microsoft.com/en-us/library/aa528822.aspx[^]

using System;
using System.IO;

class Test
{

public static void Main()
{
    // Specify a file to read from and to create.
    string pathSource = @"c:\tests\source.txt";
    string pathNew = @"c:\tests\newfile.txt";

    try
    {

        using (FileStream fsSource = new FileStream(pathSource,
            FileMode.Open, FileAccess.Read))
        {

            // Read the source file into a byte array.
            byte[] bytes = new byte[fsSource.Length];
            int numBytesToRead = (int)fsSource.Length;
            int numBytesRead = 0;
            while (numBytesToRead > 0)
            {
                // Read may return anything from 0 to numBytesToRead.
                int n = fsSource.Read(bytes, numBytesRead, numBytesToRead);

                // Break when the end of the file is reached.
                if (n == 0)
                    break;

                numBytesRead += n;
                numBytesToRead -= n;
            }
             numBytesToRead = bytes.Length;

            // Write the byte array to the other FileStream.
            using (FileStream fsNew = new FileStream(pathNew,
                FileMode.Create, FileAccess.Write))
            {
                fsNew.Write(bytes, 0, numBytesToRead);
            }
        }
    }
    catch (FileNotFoundException ioEx)
    {
        Console.WriteLine(ioEx.Message);
    }
}
}
