Uploading files in C# from any location

[mbewers1]

I'm attempting to create a method in my code which allows users to upload files from any location on their desktop.

So far, every every attempt I've used to try and code this, I get an error saying that 'Access to the path has been denied'. The error doesn't appear when I place files in the same directory in which Visual Studio is located however, uploading from there is not convenient for users.

I have looked at the FileInfo class (.DirectoryName , .FullName) and the properties within the FileUploader class (.FileName) but, unfortunately, none of these allow me to perform the action.

Can anyone suggest what library operations I need to upload files from anywhere and not just from the VisualStudio program?

where is your file located? Is it in a server or a local computer?

It's on my local PC. So is my code but, as mentioned, I am only able to upload from 1 location at the moment and that is the VisualStudio directory.

Post you code please

OK well, it's all in bits between different classes.
The following method takes a string argument which is taken from a FileUploader tool:

FileUploader.Po stedFile.FileNa me

private void CheckFileSelection(string fileName)
    {
        if(techFileUpload.HasFile)
        {
            if (reflista.SelectedValue == "BibTeX" || fileName.ToLower().EndsWith(".bib"))
            {
                BibTexItemTypes bit = new BibTexItemTypes(fileName);
                itemCount = bit.ReadBibTeXFile(fileName);
                if (itemCount == 0)
                {
                    message.Text = @"No BibTeX records were found within the file
                       and so, no records have been imported";
                }
                else
                {
                    message.Text = string.Format(@"BibTeX record imported successfully, 
                    {0} items found, {0} items added", itemCount);
                }
            }

The next part reads the contents of the file using a StreamReader and uses a
File.OpenText property to start this off, don't know if this makes any difference but I've posted it anyway.

public int ReadBibTeXFile(string fileName)
    {
        using (StreamReader sr = File.OpenText(fileName))
        {
            while (!sr.EndOfStream)
            {
                string line = sr.ReadLine();

                if (line.Contains("@article"))
                {
                    ArticleProcess(sr);
                }
 
                // other statements

Someone else told me a while back that there is some sort of a 'FileManager' tool to help this but it doesn't appear that this is a class or a tool that can be used within the .NET framework.

It's on my local PC.

I suspect you are getting lost in termonolgy.

If the source file is on your PC, and you are just copying it to the desktop then it isn't an upload - its a file copy and can be done with

System.IO.File. Copy(string source, string destination);

If the source file is on an internet server someplace then you still aren't uploading - you are downloading. The files come DOWN from a server, or UP to a server. Which means if you have the terms backwords you are probably using the wrong tool for you intention.

Avoiding errors in uploading

I didn't want to move a file to another location, I wanted to store the details in the database but It's OK, I've solved the problem.

What I did was add the line:

byte[] byteArr = File.ReadAllBytes(fileName)

;

to read the file as a byte array, then I passed the byte array to my file-handling classed called BibTexItemTypes .

BibTexItemTypes bit = new BibTexItemTypes(byteArr);

Then plugged the byte array into a StreamReader, so we could read the file line by line and determine therefore, which parts of the file go into the database and where.

Stream s = new MemoryStream(byteArr);
StreamReader bibTex = new StreamReader(s);
