get FTP file upload completed properly
I am using below code to upload files to web server FTP . In the below code i am facing some problems. I want the file to be completely uploaded and then control should come out of this function. Now in some cases control comes out of this function when some connection error occurs etc.I get error in catch .But even though error catches upload sometimes continues. So i want to know whether upload completed completely and then only come out of this function. How i can do it?
I tried checking file size of the uploading file using Ftp.GetFileSize .but even after all bytes uploaded it returns "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)." error.
So how i can check file uploaded completely?
Code:
Public Function Upload(ByVal fi As FileInfo) As Boolean
Dim URI As String = Hostname '' website is set here
'perform copy
Dim ftp As Net.FtpWebRequest = GetRequest(URI)
'Set request to upload a file in binary
ftp.Method = Net.WebRequestMethods.Ftp.UploadFile
ftp.UseBinary = True
'Notify FTP of the expected size
ftp.ContentLength = fi.Length
Const BufferSize As Integer = 400000000
Dim content(BufferSize - 1) As Byte, dataRead As Integer
'open file for reading
Using fs As FileStream = fi.OpenRead()
Try
'open request to send
Using rs As Stream = ftp.GetRequestStream
Do
dataRead = fs.Read(content, 0, BufferSize)
rs.Write(content, 0, dataRead)
Loop Until dataRead < BufferSize
rs.Close()
End Using
Catch ex As Exception
Finally
'ensure file closed
fs.Close()
End Try
End Using
ftp = Nothing
Return True
End Function

Re: get FTP file upload completed properly
Why do you catch the exception, ignore it and then always return true? I would start by returning false when an exception occurs. How you proceed from that point may depend upon what the exception is.
