Upload file on FTP

Question

I want to upload file from one server to another FTP server and following is my code to upload file but it is throwing an error as:

The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

This my code:

string CompleteDPath = "ftp URL";
string UName = "UserName";
string PWD = "Password";
WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName);
reqObj.Method = WebRequestMethods.Ftp.UploadFile;
reqObj.Credentials = new NetworkCredential(UName, PWD);
FileStream streamObj = System.IO.File.OpenRead(Server.MapPath(FileName));
byte[] buffer = new byte[streamObj.Length + 1];
streamObj.Read(buffer, 0, buffer.Length);
streamObj.Close();
streamObj = null;
reqObj.GetRequestStream().Write(buffer, 0, buffer.Length);
reqObj = null; 

Can you please tell me where i am going wrong?

Answer 1

In case you're still having issues here's what got me past all this. I was getting the same error in-spite of the fact that I could perfectly see the file in the directory I was trying to upload - ie: I was overwriting a file.

My ftp url looked like:

// ftp://www.mywebsite.com/testingdir/myData.xml
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.mywebsite.com/testingdir/myData.xml"

So, my credentials use my tester username and PW;

request.Credentials = new NetworkCredential ("tester", "testerpw");

Well, my "tester" ftp account is set to "ftp://www.mywebsite.com/testingdir" but when I actually ftp [say from explorer] I just put in "ftp://www.mywebsite.com" and log in with my tester credentials and automatically get sent to "testingdir".

So, to make this work in C# I wound up using the url - ftp://www.mywebsite.com/myData.xml Provided my tester accounts credentials and everything worked fine.
