win7搭建ftp服务器及文件上传

参考

http://www.cnblogs.com/yangpaopao/archive/2010/07/30/1788513.html

1、到控制面板---程序---打开或关闭windows功能，列表内找到Internet信息服务（展开）---选中FTP的三个项

2、到控制面板---系统和安全---管理工具---Internet 信息服务(IIS)管理器---右键点你计算机名称那里，选择添加FTP站点

3、FTP站点名称输入："localhost"---选择你的FTP目录物理路径，点下一步---Ip地址选“自己的IP”，端口可以自己设，勾上“自动FTP站点”，SSL选“允许”

点下一步---身份验证选“匿名”，允许访问选“匿名用户”，权限勾“读取”或“写入”，点完成。

4、到控制面板---系统和安全---允许程序通过防火墙---钩上FTP及后面两个框框。

现在在WIN7系统 下通过自带的IIS搭建的匿名FIP就已成功，我们可以通过输入FTP的地址来进行数据的上传与下载。

文件上传函数

  public static int UploadFtp(string filePath, string filename, string ftpServerIP, string ftpUserID, string ftpPassword)
        {

            FileInfo fileInf = new FileInfo(filePath + "\" + filename);
            string uri = "ftp://" + ftpServerIP;
            FtpWebRequest reqFTP;

            // Create FtpWebRequest object from the Uri provided
            reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + fileInf.Name));
            try
            {
                // Provide the WebPermission Credintials
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                reqFTP.UsePassive = false; 
                // By default KeepAlive is true, where the control connection is not closed
                // after a command is executed.
                reqFTP.KeepAlive = false;

                // Specify the command to be executed.
                reqFTP.Method = WebRequestMethods.Ftp.UploadFile;

                // Specify the data transfer type.
                reqFTP.UseBinary = true;

                // Notify the server about the size of the uploaded file
                reqFTP.ContentLength = fileInf.Length;

                // The buffer size is set to 2kb
                int buffLength = 2048;
                byte[] buff = new byte[buffLength];
                int contentLen;

                // Opens a file stream (System.IO.FileStream) to read the file to be uploaded
                //FileStream fs = fileInf.OpenRead();
                FileStream fs = fileInf.Open(FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

                // Stream to which the file to be upload is written
                Stream strm = reqFTP.GetRequestStream();

                // Read from the file stream 2kb at a time
                contentLen = fs.Read(buff, 0, buffLength);

                // Till Stream content ends
                while (contentLen != 0)
                {
                    // Write Content from the file stream to the FTP Upload Stream
                    strm.Write(buff, 0, contentLen);
                    contentLen = fs.Read(buff, 0, buffLength);
                }

                // Close the file stream and the Request Stream
                strm.Close();
                fs.Close();
                return 0;
            }
            catch (Exception ex)
            {
                reqFTP.Abort();
                return -2;
            }
        }
调用： UploadFtp("D:\", "temp.txt", "192.168.1.106:2121", "anonymous", "111");
