上传时无法在asp网络中找到文件错误 [英] Could not find file error in asp net when upload

问题描述

我使用此代码上传ftp：

  protected   void  LinkBut​​ton1_Click（ object  sender，EventArgs e）
 {
  string  filename = System.IO.Path.GetFileName（FileUpload1.PostedFile.FileName）; 
 
  string  ftpServerIP =   *; 
  string  ftpUserName =   *; 
  string  ftpPassword =   *; 
 FileInfo objFile =  new  FileInfo（filename）; 
 FtpWebRequest objFTPRequest; 
 objFTPRequest =（FtpWebRequest）FtpWebRequest.Create（ new  Uri（ftpServerIP +   / + objFile.Name））; 
 objFTPRequest.Credentials =  new  NetworkCredential（ftpUserName，ftpPassword）; 
 
 objFTPRequest.KeepAlive =  false ; 
 objFTPRequest.UseBinary =  true ; 
 objFTPRequest.ContentLength = objFile.Length; 
 objFTPRequest.Method = WebRequestMethods.Ftp.UploadFile; 
 
  int  intBufferLength =  16  *  1024 ; 
  byte  [] objBuffer =  new   byte < /跨度> [intBufferLength]; 
 FileStream objFileStream = objFile.OpenRead（）; 
  try  
 {
 Stream objStream = objFTPRequest.GetRequestStream（）; 
  int  len =  0 ; 
  while （（len = objFileStream.Read（objBuffer， 0 ，intBufferLength））！=  0 ）
 {
 objStream.Write（objBuffer， 0 ，len）; 
} 
 objStream.Close（）; 
 objFileStream.Close（）; 
 Console.Write（ 文件上传成功...）; 
} 
  catch （例外情况）
 {
  throw  ex; 
} 
} 

我的错误：

System.IO.FileNotFoundException：找不到文件'... '。

解决方案

替换以下内容



string filename = System.IO.Path.GetFileName（FileUpload1 .PostedFile.FileName）;



with



string filename = FileUpload1.PostedFile.FileName.ToString（ ）;

I use this code for upload with ftp:

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        string filename = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);

        string ftpServerIP = "*";
        string ftpUserName = "*";
        string ftpPassword = "*";
        FileInfo objFile = new FileInfo(filename);
        FtpWebRequest objFTPRequest;
        objFTPRequest = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpServerIP + "/" + objFile.Name));
        objFTPRequest.Credentials = new NetworkCredential(ftpUserName, ftpPassword);

       objFTPRequest.KeepAlive = false;
        objFTPRequest.UseBinary = true;
        objFTPRequest.ContentLength = objFile.Length;
        objFTPRequest.Method = WebRequestMethods.Ftp.UploadFile;

        int intBufferLength = 16 * 1024;
        byte[] objBuffer = new byte[intBufferLength];
        FileStream objFileStream = objFile.OpenRead();
        try
        {
            Stream objStream = objFTPRequest.GetRequestStream();
            int len = 0;
            while ((len = objFileStream.Read(objBuffer, 0, intBufferLength)) != 0)
            {
                objStream.Write(objBuffer, 0, len);
            }
            objStream.Close();
            objFileStream.Close();
            Console.Write("File upload success...");
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

my error :
System.IO.FileNotFoundException: Could not find file '...'.

解决方案

Replace the following

string filename = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);

with

string filename = FileUpload1.PostedFile.FileName.ToString();
