Is there a method to manage relative paths in C#? [duplicate]

I have xml files that contain href file paths to images (e.g. "....\images\image.jpg"). The hrefs contain relative paths. Now, I need to extract the hrefs to the images and turn them into absolute paths in the file system.
I know about the GetFullPath method, but I tried it and it only seems to work from the CurrentDirectory set, which appears to be C: so I don't see how I could use that. And still, I have the absolute path of the file containing the hrefs, and the href relative paths, so since it is a simple task for me to count back the number of "....\" parts based on the absolute path of the containing file, it seems there must be a way to do this programmatically as well.
I'm hoping there's some simple method I just don't know about! Any ideas?

string exactPath = Path.GetFullPath(yourRelativePath);
works

Assuming you know the real directory the XML file lives in use Path.Combine, e.g.
var absolute_path = Path.Combine(directoryXmlLivesIn, "..\images\image.jpg");
If you want to get back the full path with any ..'s collapsed then you can use:
Path.GetFullPath((new Uri(absolute_path)).LocalPath);

This worked.
var s = Path.Combine(#"C:\some\location", #"..\other\file.txt");
s = Path.GetFullPath(s);

It`s best way for convert the Relative path to the absolute path!
string absolutePath = System.IO.Path.GetFullPath(relativePath);

You can use Path.Combine with the "base" path, then GetFullPath on the results.
string absPathContainingHrefs = GetAbsolutePath(); // Get the "base" path
string fullPath = Path.Combine(absPathContainingHrefs, #"..\..\images\image.jpg");
fullPath = Path.GetFullPath(fullPath); // Will turn the above into a proper abs path

Have you tried Server.MapPath method. Here is an example
string relative_path = "/Content/img/Upload/Reports/59/44A0446_59-1.jpg";
string absolute_path = Server.MapPath(relative_path);
//will be c:\users\.....\Content\img\Upload\Reports\59\44A0446_59-1.jpg

This worked for me.
//used in an ASP.NET MVC app
private const string BatchFilePath = "/MyBatchFileDirectory/Mybatchfiles.bat";
var batchFile = HttpContext.Current.Server.MapPath(BatchFilePath);

How do I remove version number from file path? - Winforms c#

I am wondering how to remove the version number from a file path in a Windows Form Application.
Currently I wish to save some users application data to a .xml file located in the roaming user profile settings.
To do this I use:
get
{
return Application.UserAppDataPath + "\\FileName.xml";
}
However this returns the following string:
C:\Users\user\AppData\Roaming\folder\subfolder\1.0.0.0\FileName.xml
and I was wondering if there is a non-hack way to remove the version number from the file path so the file path looks like this:
C:\Users\user\AppData\Roaming\folder\subfolder\FileName.xml
Besides parsing the string looking for the last "\", I do not know what to do.
Thanks

Use Directory.GetParent method for this purpose.
get
{
var dir = Directory.GetParent(Application.UserAppDataPath);
return Path.Combine(dir.FullName, "FileName.xml");
}
Also note that I've used Path.Combine instead of concatenating paths, this method helps you to avoid so many problems. Never concatenate strings to create path.

C# Adding Program To Run Will Not Add Full Path

There is something weird with the way I add to registry run.
When I use
private static string AppPath = new Uri((System.Reflection.Assembly.GetExecutingAssembly().CodeBase)).LocalPath;
to set the path in run registry it worked fine, but if folder name is "c#" for example the added key will be cut before #
so should be :
c:/desktop/c#/myprogram.exe
but it's
c:/desktop/c
What's the problem can you guys help?

I think there is an issue with the Uri escape symbols. Try this:
string AppPath = System.Reflection.Assembly.GetExecutingAssembly ().Location;

I can't duplicate what you're seeing. I think maybe you're missing some information:
var uri = new Uri("c:/desktop/c#/myprogram.exe");
string raw = uri.ToString(); // "file:///c:/desktop/c%23/myprogram.exe"
string local = uri.LocalPath; // "c:\desktop\c#\myprogram.exe"
Are you sure about what's coming out of the Codebase property there?

This happens because the # character gets encoded in the Uri and becomes %23 instead.
I'm not sure why you want to use Uri to get the location of the executable. There is a better way (as nightsnaker posted).
However, if you must use an Uri (for whatever reason), you can get the full path by doing something like this:
string s = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
Uri u = new Uri(s);
string local = u2.LocalPath+u2.Fragment.Replace('/','\\');

Converting physical path to relative one in respect of http://localhost:

I use asp.net 4 and c#.
I have this code that allow me to find the physical path for an image.
As you can see I get my machine physical pagh file:///C:.
string pathRaw = HttpContext.Current.Request.PhysicalApplicationPath + "Statics\\Cms\\Front-End\\Images\\Raw\\";
Result:
file:///C:/......../f005aba1-e286-4d9e-b9db-e6239f636e63.jpg
But I need display this image at the Front end of my web application so I would need a result like this:
http://localhost:1108/Statics/Cms/Front-End/Images/Raw/f005aba1-e286-4d9e-b9db-e6239f636e63.jpg
How to do it?
PS: I need to convert the result of variable pathRaw.
Hope I was able to express myself unfortunately I'm not sure about terminology in this case.
Thanks for your help!

The easiest thing to do is get rid of the physical application path.
If you cannot do that in your code, just strip it off the pathRaw variable. Like this:
public string GetVirtualPath( string physicalPath )
{
if ( !physicalPath.StartsWith( HttpContext.Current.Request.PhysicalApplicationPath ) )
{
throw new InvalidOperationException( "Physical path is not within the application root" );
}
return "~/" + physicalPath.Substring( HttpContext.Current.Request.PhysicalApplicationPath.Length )
.Replace( "\\", "/" );
}
The code first checks to see if the path is within the application root. If not, there's no way to figure out a url for the file so an exception is thrown.
The virtual path is constructed by stripping off the physical application path, convert all back-slashes to slashes and prefixing the path with "~/" to indicate it should be interpreted as relative to the application root.
After that you can convert the virtual path to a relative path for output to a browser using ResolveClientUrl(virtualPath).

Get the root of your application using Request.ApplicationPath
then use the answer from this question to get a relative path.
It might need a bit of tweaking but it should allow you to do what you're after.

Left-strip your pathRaw content by the Request.ApplicationPath and construct the url using
Uri navigateUri = new Uri(System.Web.HttpContext.Current.Request.Url, relativeDocumentPath);

Make use of
ApplicationPath - Gets the ASP.NET application's virtual application root path on the server.
Label1.Text = Request.ApplicationPath;
Image1.ImageUrl = Request.ApplicationPath + "/images/Image1.gif";

You can use Server.MapPath for this.
string pathRaw = System.Web.HttpContext.Current.Server.MapPath(“somefile.jpg“);
