Problem with file path
-
I'm trying to use a upload form to read a file. The problem is, I cant access full path of the file so I can read wherever he is. The form is something like this:
<form id="Form1" enctype="multipart/form-data" runat="server">
<tr>
<td>Escolha ficheiro:</td>
<td><input id="upl" type="file" runat="server"></td>
</tr>
<tr>
<td colspan="2">
<input type="button" id="upload" value="Inserir"
OnServerClick="uploadClick" runat="server">
</td>
</tr>
</form>The problem its here:
string path; path = upl.Value; Response.Write(path);Using VS 2008 I can see that when I use "Value" I am "acessing full file path on client's computer". Its exactly what I want but I'm getting on the output just the name of the file. Its very strange because also when I browse the file the textfield shows the full path. Also, if I change the type="file" to type="text" and then I input the path manually, everything works right. What am I doing wrong?

Do .txt data to SQL table operation. I'm not doing upload operation, I'm doing insert operation using upload form. The client machine is always the user machine so there's no problem. The following line its: string[] data = File.ReadAllLines(path); If there's another (and better) way, please say to me.

Why are you using pure HTML and not server controls ? Why not use a server control and just grab the file data from the stream you get passed ? Surely you're not saying your application is only ever used by someone who is on the server ? If it's never used over the internet, or a LAN, why use ASP.NET at all ?

Old habits... What I meant to say is that the method I was trying to use works because the file its always on client side, so why not open and read data on client side and write it on server side? I work on ASP.NET less than 48 hours so I dont know a server control to do that. By server control you mean something like this: ? <asp:FileUpload ID="FileUpload1" runat="server" /> What would be the diference?

Because your C# code never runs on the client, it runs on the server.

This control has a property that contains the bytes of the file in question.

I followed your advice and done:
caminho = Path.GetFullPath(FileUploadControl.PostedFile.FileName);
and
cam = Path.GetFullPath(FileUploadControl.PostedFile.FileName);
and another tries, and always have same result: C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\file.txt (is not even the same hard drive) I googled about it, and looks like File Upload Control does not allow getting full path of client's machine. They say its a security thing.

You didn't remotely follow my advice. you CANNOT access the file from the server to the client. The PostedFile property has a property which contains the file contents.

You are right. I found this. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.postedfile.aspx[^] I've adapted to my program, but having the problem I tought. If I use streams to read the file, I will not have text data. So I'm trying convert that stream data using:
StreamReader reader = new StreamReader( myStream );
string text = reader.ReadToEnd();and
byte[] bytes = new byte[myStream.Length];
string data = Encoding.ASCII.GetString(bytes);But its not working :^) EDIT: I did this and its finally working :-D
byte\[\] bytes = new byte\[myStream.Length\]; myStream.Position = 0; myStream.Read(bytes, 0, (int)myStream.Length); string data = Encoding.ASCII.GetString(bytes);modified on Thursday, November 12, 2009 1:05 PM
