  file exist on sever

  May 03, 2012 08:14 AM|LINK

  I want to check if a file exists on server's disk and I am using following code

  if (File.Exists(Server.MapPath("~/Jaram Images/") + Path.GetFileName(product.Pic_Url2)))
  {
  WriteError("File exist!");

  PdfProdCell = new PdfPCell(iTextSharp.text.Image.GetInstance(Server.MapPath("~/Jaram Images/") + Path.GetFileName(product.Pic_Url2)), true);
  }
  else
  WriteError(Server.MapPath("~/Jaram Images/") + " File doesn't exist!");

  but I am getting this error:

  public static void WriteError(string errorMessage)
  {
  try
  {
  string path = "~/Jaram PDF/PDFS/" + DateTime.Today.ToString("dd-mm-yy") + ".txt";
  if (!File.Exists(System.Web.HttpContext.Current.Server.MapPath(path)))
  {
  File.Create(System.Web.HttpContext.Current.Server.MapPath(path)).Close();
  }
  using (StreamWriter w = File.AppendText(System.Web.HttpContext.Current.Server.MapPath(path)))
  {
  w.WriteLine("\r\nLog Entry : ");
  w.WriteLine("{0}", DateTime.Now.ToString(CultureInfo.InvariantCulture));
  string err = "Error in: " + System.Web.HttpContext.Current.Request.Url.ToString() +
  ". Error Message:" + errorMessage;
  w.WriteLine(err);
  w.WriteLine("__________________________");
  w.Flush();
  w.Close();
  }
  }
  catch (Exception ex)
  {
  WriteError(ex.Message);
  }

  }

  Log Entry :
  05/03/2012 15:50:51

  Simple code.

  using System;
  using System.IO;
  
  class Test
  {
      public static void Main()
      {
          string resumeFile = @"c:\ResumesArchive\923823.txt";
          string newFile = @"c:\ResumesImport\newResume.txt";
          if (File.Exists(resumeFile))
          {
              File.Copy(resumeFile, newFile);
          }
          else
          {
              Console.WriteLine("Resume file does not exist.");
          }
      }
  }

  BAAZ.
  
  Mark answer if it helps.

  Hi,

  sparrow37

  I want to check if a file exists on server's disk and I am using following code

  Check your source code, you use File.Existe method to determine whether the specified file exists. You source code appears to look ok, and you also can get the error information from a txt file. That proves your source code did work. I'm not sure what your question is exactly, please check  the both references below:

  http://msdn.microsoft.com/en-us/library/system.io.file.exists.aspx

  http://msdn.microsoft.com/en-us/library/system.io.fileinfo.exists.aspx

  And I suggest you to debug your soucec code step by step to determine what happends and how your source code executes.

  Please mark the replies as answers if they help or unmark if not.
