hi ,

HttpFileCollection uploadFilCol = Request.Files;
try
{
for (int i = 0; i < uploadFilCol.Count; i++) //uploadFilCol.Count
{
HttpPostedFile file = uploadFilCol[i];
string fileExt = Path.GetExtension(file.FileName).ToLower();
string fileName = Path.GetFileName(file.FileName);
if (file.ContentLength > 0)
{
if (fileName != string.Empty)
{
createdir(ftpaddress + Session["userid"].ToString(), user, pass);
try
{
if (fileExt == ".jpg" || fileExt == ".gif" || fileExt == ".png" || fileExt == ".jpeg" || fileExt == ".rar" || fileExt == ".zip" || fileExt == ".7z")
{
FtpWebRequest uploadRequest = (FtpWebRequest)FtpWebRequest.Create(ftpaddress + Session["userid"].ToString() + @"/" + fileName);
Stream requestStream = null;
FtpWebResponse uploadResponse = null;
try
{
Thread.Sleep(20);
uploadRequest.Credentials = new NetworkCredential(user, pass);
uploadRequest.KeepAlive = false;
uploadRequest.UsePassive = false;
uploadRequest.Method = WebRequestMethods.Ftp.UploadFile;
uploadRequest.UseBinary = true;
uploadRequest.Timeout = 10000000;
byte[] buffer = null;
uploadRequest.Proxy = null;
requestStream = uploadRequest.GetRequestStream();
long bytesToRead = file.ContentLength;
int bytesRead = 0;
while (bytesRead < bytesToRead)
{
buffer = new byte[file.ContentLength];
bytesRead += file.InputStream.Read(buffer, 0, buffer.Length);
if (bytesRead == 0)
break;
requestStream.Write(buffer, 0, bytesRead);
}
requestStream.Close();
uploadResponse = (FtpWebResponse)uploadRequest.GetResponse();
}
catch (UriFormatException ex)
{
lbl_error.Text = ex.Message;
}
catch (IOException ex)
{
lbl_error.Text = ex.Message;
}
catch (WebException ex)
{
lbl_error.Text = ex.Message;
}
finally
{
if (uploadResponse != null)
uploadResponse.Close();
if (requestStream != null)
requestStream.Close();
}
this.ShowMessage("" + fileName + " Uploaded ", i);

{
this.ShowMessage(" <font color=red> This is not a Picture File</font/>", i);
}
//}
}
catch (Exception ex)
{
this.ShowMessage("<font color=red> " + fileName + " Not Uploaded <font>", i);
}
}
}
else
{
this.ShowMessage("<font color=red> " + fileName + " File size not more than 6MB</font>", i);
}
}
}

Response.Redirect("default.aspx");

但是在将站点托管在服务器上后，它不起作用..也就是说，文件未上传..而且它也没有返回任何错误..我缺少什么吗?..请帮助我...

推荐答案
HI尝试执行以下操作
1.检查ftp主机地址和配置文件以更新服务器详细信息
2. Alos检查凭据，如果没有权限，则文件也不会上传到服务器
HI try to do the followings
1. Check the ftp host address,and config file for updating server details
2. Alos check the credentials , if no permission then also file will not get uploaded to server
ftp.Credentials = new NetworkCredential("userid", "password");
//userid and password for the ftp server to given
3.在创建FtpWebRequest.Create时，为什么要传递Session ID，请检查并尝试执行以下操作
3. While creating FtpWebRequest.Create why you are passing Session ID please check, and try to do as below
string ftpfullpath = "ftp://" + ftphost + ftpfilepath;
FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
我认为许可问题.检查asp.net和网络安全性的权限设置.如果未设置权限文件，则不会保存在服务器中.
I think the problem of permission. check the permission settings for asp.net and network security. if you not set permission file will not save in server.
如果您需要上传4MB以上的文件，可以在wen.config
中使用此代码
if you need to upload more than 4MB you can this code in wen.config
<httpRuntime
maxRequestLength="4096"
