Asp.Net_上传文件(ftp、webClient、webService)

第一种：通过FTP来上传文件

首先，在另外一台服务器上设置好FTP服务，并创建好允许上传的用户和密码，然后，在ASP.NET里就可以直接将文件上传到这台 FTP 服务器上了。代码如下：

<%@ Page Language="C#" EnableViewState="false"%>

<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
  protected void Button1_Click(object sender, EventArgs e)
  {
    //要接收文件的 ftp 服务器地址
    String serverUri = "ftp://192.168.3.1/";
    String fileName = Path.GetFileName(FileUpload1.FileName);
    serverUri += fileName;

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
request.Method = WebRequestMethods.Ftp.AppendFile;
request.UseBinary = true;
request.UsePassive = true;

// ftp 服务器上允许上传的用户名和密码
request.Credentials = new NetworkCredential("upload", "upload");
Stream requestStream = request.GetRequestStream();
Byte[] buffer = FileUpload1.FileBytes;

requestStream.Write(buffer, 0, buffer.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Label1.Text = response.StatusDescription;
response.Close();
}
</script>
