File.Copy keeps trying to find a server url by looking for it in my C drive

I am trying to run the File.Copy function so that I can use a template file I have to make a new word document that the code will fill out. Whenever the code gets to the file.copy function I get the error
"IOException: The filename, directory name, or volume label syntax is incorrect : 'C:\Software\DRAT\DRAT*serverpath*\SoftwareReleaseTool\Trunk\ReleaseNotesTemplates\ReleaseNotes1.docx'"
I want the filename to be
"serverpath\SoftwareReleaseTool\Trunk\ReleaseNotesTemplates\ReleaseNotes1.docx"
The first part, "C:\Software\DRAT\DRAT\" is the directory that the project is in. I cannot find out why it keeps looking in this directory for the server link.
I watch the local values before the function is run and they are correct. I get
"serverpath/Fusion/Main\Releases\Notes\VCM-1.1.43-SoftwareReleaseNotes.docx"
for notes.ReleaseNotesPath and
"serverpath/SoftwareReleaseTool/Trunk/ReleaseNotesTemplates/ReleaseNotes1.docx"
for templatePath.
If I use the paths to the same files that are on my local drive it works, but I need to use the SVN server links so that my co-workers can access the same file from their computers.
Here is the file.copy function that is called:
File.Copy(templatePath, notes.ReleaseNotesPath, true);
templatePath is filled out by the user, where I input "serverpath/SoftwareReleaseTool/Trunk/ReleaseNotesTemplates/ReleaseNotes1.docx"
notes.ReleaseNotesPath is defined here:
notes.ReleaseNotesPath = buildFiles[0] + #"\Releases\Notes\VCM-" + model.ReleaseVersion + "-SoftwareReleaseNotes.docx";
the buildFiles[0] part of it is "serverpath/FusionTest/Main"
I should be making new word document but instead I keep getting the same IOException every time.

File.Copy only works in your local file system. You should try something like System.Net.WebClient.DownloadFile
e.g:
using (var client = new WebClient())
{
client.DownloadFile("https://ags-iv-engrpub/svn/SoftwareReleaseTool/Trunk/ReleaseNotesTemplates/ReleaseNotes1.docx", "ReleaseNotes1.docx");
}

Saving images from IP Camera to folder in application

I have a camera connected to a network that provides images which can be accessed by IP. For example something like this.
http://170.1.2.3/image?camera=2
I get returned a jpg file, which I can easily display back on a webpage using normal html.
<img src="http://170.1.2.3/image?camera=2" />
But instead of simply showing the camera image as seen from the time of the page load, I also want to save this image locally to the server using an MVC4 application. In addition it would be nice to include a timestamp on the filename. I'm not having any luck finding an example that looks right to me.
Let's say I want to start with the most basic example:
string imgUrl = "http://170.1.2.3/image?camera=2";
savelocally(imgurl, "newfilename-"+DateTime.Now.ToString());
.. and savelocally() should place the file in "~/Uploads". How do I do this? All the examples I've come across have been for uploading a file from desktop. I don't know how to translate that into grabbing a remote image.
Update:
This is an incomplete answer, as pointed out by comments.
string url = "http://170.1.2.3/image?camera=2";
string localFilename = #"C:\Projects\MvcApplication1\MvcApplication1\Uploads\tofile.jpg";
using (WebClient client = new WebClient())
{
client.DownloadFile(url, localFilename);
}
It works, however I don't like the fact that the file path is an absolute one. I tried replacing localFilename with ~/Uploads/tofile.jpg but it results in an error on execution. If possible I want to avoid having a fixed location for the upload folder.

C# SharpZipLib extract .TGZ NotSupportedException

I'm new to programming so please be patient.
I am currently developing a small Program in Visual C# 2010 Express, .NET Framework 4.0, which starts a Script on a Linux Machine (what creates the File /tmp/logs.tgz), downloads the File and then I want to extract it. Running the Script and downloading the File via Renci.SshNet works flawlessly.
But when I want to extract it, it gives me an Error "NotSupportedException" my Filepath Format is incorrect (which is not the case, I think?).
I copy and pasted the Code directly from here (Simple full extract from a TGZ (.tar.gz)) and edited it for my Needs:
using System.IO;
using System.IO.Compression;
using ICSharpCode.SharpZipLib.GZip;
using ICSharpCode.SharpZipLib.Tar;
//it executed the Script and created the file on the Linux Machine /tmp/logs.tgz
//now I want to download it
string myTime = DateTime.Now.ToString("yyyyMMdd");
var pathWithEnv = (#"%USERPROFILE%\Desktop\logs" + myTime + ".tgz");
var filePath = Environment.ExpandEnvironmentVariables(pathWithEnv);
string localFile = filePath;
//then downloads /tmp/logs.tgz to ..\Desktop\logs+ myTime +.tgz
//everything great until now. here I want to extract .TGZ:
var pathWithEnv2 = (#"%USERPROFILE%\Desktop\logs" + myTime);
var fileDir = Environment.ExpandEnvironmentVariables(pathWithEnv2);
string localDir = fileDir;
Stream inStream = File.OpenRead(localFile);
Stream gzipStream = new GZipInputStream(inStream);
TarArchive tarArchive = TarArchive.CreateInputTarArchive(gzipStream);
//ERROR OCCURS HERE:
tarArchive.ExtractContents(localDir);
tarArchive.Close();
gzipStream.Close();
inStream.Close();
I even tried to set the localFile and localDir string without the EnviromentVariable, but that didnt help. I tried:
- download and extract it directly on C:\ (or on a mapped Network Drive U:) to prevent too long filenames (which should not be the case as it should never get longer than 86 characters).
- string = #"C:..\logs", string = "C:\..\logs", string = #"C:..\logs\", etc.
- tried it without myTime
- using ICSharpCode.SharpZipLib.Core;
I did a MessageBox.Show(localDir); before the tarArchive.ExtractContents(localDir); and it showed "C:\Users\Baumann\Desktop\logs20140530" which is correct, thats the Directory I want to extract it to. Even creating the Directory before executing it doesn't help.
I also created a new Project with just one button which should start the Extraction and the same error occurs.
I tried, doing it separately, first extract the GZip and then the .tar, but it also gives me the same Error when extracting the GZip (using ICSharpCode.SharpZipLib.Core; of course).
What drives me even more crazy about it, is, that it starts to extract it, but not everything, before it fails. And always the same Files, whats not clear for me why these and why not the others.
I'm on Windows 8.1, using SharpZipLib 0.86.0.518, downloaded directly from the Website.
Thanks in advance.

well, I finally fixed the Problem. The Linux machine is creating a file which includes the MAC-Adress and since Windows can't handle ":" in a Filename, it crashes.
I am now extracting file by file and checking each file for ":" and replacing it with "_", works flawlessly.

How to read file in C# from POST data from web

Basically, I'm building a website that allows user to upload file.
From the front end (JavaScript), the user will browse a file, I can get the site to send POST data (the parameter "UploadInput" and it's value, which the value is the file)
In the backend (C#), I want to make a copy of the file and save it in a specific path.
Below is the way I did it.
var files = Request.Files;
file[0].SaveAs("\temp\\" + file[0].FileName);
The problem I ran into is that I got the error message saying index out of range. I tried Response.Write(files.Count) and it gives me 0 instead of 1.
I'm wondering where I did wrong and how to fix it, or if there's a better way of doing it.
Thanks!
Edit:
I am using HttpFox to debug. From HttpFox, I can see that under POST data, parameter is "UploadInput" and the value is "test.txt"
Edit 2:
So I tried the way Marc provides, and I have a different problem.
I am able to create a new file, however, the content is not copied over. I tried opening the new created file in notepad and all it says is "UploadInput = test.txt"

If they simply posted the file as the body content, then there will be zero "files" involved here, so file[0] will fail. Instead, you need to look at the input-stream, and simply read from that stream. For example:
using(var file = File.Create(somePath)) {
Request.InputStream.CopyTo(file);
}

User Permissions issue

I am using Visual Studio C# to parse an XML document for a file location from a local search tool I am using. Specifically I am using c# to query if the user has access to certain files and hide those to which it does not have access. I seem to have files that should return access is true however because not all files are local (IE some are web files without proper names) it is not showing access to files it should be showing access to. The error right now is caused by a url using .aspx?i=573, is there a work around or am I going to have to just remove all of these files... =/
Edit: More info...
I am using right now....
foreach (XmlNode xn in nodeList)
{
string url = xn.InnerText;
//Label1.Text = url;
try
{ using (FileStream fs = File.OpenRead(url)) { }
}
catch { i++; Label2.Text = i.ToString(); Label1.Text = url; }
}
The issue is, when it attempts to open files like the ....aspx?i=573 it puts them in the catch stack. If I attempt to open the file however the file opens just fine. (IE I have read access but because of either the file type or the append of the '?=' in the file name it tosses it into the unreadable stack.
I want everything that is readable either via url or local access to display else it will catch the error files for me.

I'm not sure exactly what you are trying to do, but if you only want the path of a URI, you can easily drop the query string portion like this:
Uri baseUri = new Uri("http://www.domain.com/");
Uri myUri = new Uri(baseUri, "home/default.aspx?i=573");
Console.WriteLine(myUri.AbsolutePath); // ie "home/default.aspx"
You cannot have ? in file names in Windows, but they are valid in URIs (that is why IE can open it, but Windows cannot).
Alternatively, you could just replace the '?' with some other character if you are converting a URL to a filename.
In fact thinking about it now, you could just check to see if your "document" was a URI or not, and if it isn't then try to open the file on the file system. Sounds like you are trying to open any and everything that is supplied, but it wouldn't hurt to performs some checks on the data.
private static bool IsLocalPath(string p)
{
return new Uri(p).IsFile;
}
This is from Check if the path input is URL or Local File it looks like exactly what you are looking for.

FileStream reads and writes local files. "?" is not valid character for local file name.
It looks like you want to open local and remote files. If it is what you are trying to do you should use approapriate metod of downloading for each type - i.e. for HTTP you WebRequest or related classes.
Note: it would be much easier to answer if you'd say: when url is "..." File.OpenRead(url) failes with exception, mesasge "...".
