Get onedrive file URL from a the locally cached file

I am looking for a way to derive the OneDrive file URL for a file cached to my local OneDrive folder? The only thing I can think of is hardcoding some root URLS for each of the OneDrive folders I have, but this seems nasty!
Does anyone know of any OneDrive client API that lets query a URL based on the local file path?
My use case:
I am trying to attach to and open instance of an Excel workbook. I used to be able to do this Marshal.BindToMoniker(_workbookPath);
However it appears that Excel is now registering the OneDrive URL in the ROT rather than the local file path. This this happened with the update that brought the new auto-save feature to Excel 2016 I think, that seems to be about the time my existing code broke.
There is a similar unanswered question here: C# OneDrive for Business / SharePoint: get server path from locally synced file

Might want to use the following key instead:
HKEY_CURRENT_USER\Software\SyncEngines\Providers\OneDrive
This includes the following registry values:
UrlNamespace: (SharePoint site URL)
MountPoint: (local driver location)
It does appear to include old values which are no longer synced - but it shouldn't be too hard to check against
HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache
or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager
for paths that are being actively synced.

I am also looking at a solution for getting the SharePoint url to a file in OneDrive Synced File Explorer.
I have noticed you get under C:\Users%username%\AppData\Local\Microsoft\OneDrive\settings\Business1{GUID}.ini a mapping between your OneDrive synced folder and the SharePoint GUID
Example:
libraryScope = 1 630c2a866d9c458b81060eff107887ed+1 5 "GUIDEs" "Documents" 4 "https://mytenant.sharepoint.com/teams/team_10000035" "8d4b558f-7b2e-40ba-ad1f-e04d79e6265a" e0266a43caf347238f684bab486f4e51 e0d25dcb1a014f5f86d787984f6327c2 4f86b3e3e54e42e0bb0f7a58eadf0335 0 "" 0 4cde5c00-3fe3-4162-b831-d8ef440e1593 libraryFolder = 0 1 8bbfe07dfeff41cea7ab5da4a554592a+1 1558084235 "D:\DSUsers\uid41890\TenantName\GUIDEs - General" 2 "General" bd0c1b7c-2a1f-4492-8b1b-8e152c9e0c26
You also have this mapping in the registry Computer\HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache
From the GUID you could get the path using SPWeb.GetFile(Guid)
If you can make a standalone function given a local OneDrive file path that returns the SharePoint url, I would greatly appreciate you share your solution here.

I have implemented a solution in AutoHotkey see documentation here
It is based on #GWD idea (see comments below) to generate a temporary excel file with the formula CELL("filename") at each sync locations to extract this mapping information to a text file that is then later parsed to do the reverse mapping from local file to SharePoint url.

How to get the folder location on server with the domain name

I'm working on a c# web application which is hosted on an server 192.168.X.Y. In this application I'm accessing few documents which are inside a folder on a server 192.168.X.YYY\Folder(I'm providing this info in the Web.Config file). But the actual path of 192.168.X.YYY\Folder has a different name like abc.Application.com\Application1\Folder. How can I get this name in my c# application? Because I want to open the documents in this folder using google document viewer.
TIA :)

I used Request.ServerVariables["HTTP_HOST"] which served my purpose.

Server.MapPath specifies the relative or virtual path to map to a physical directory.
Server.MapPath(".")1 returns the current physical directory of the file is being executed
Server.MapPath("..") returns the parent directory
Server.MapPath("~") returns the physical path to the root of the application
Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

Getting the link for a virtual directory

I have written a server in C# for a JS client.
The Solution consists restApi BL and DAL.
The BL creates links for images stored on a virtual directory, on the server.
The JS and the server code, are stored in the same directory.
When I build the string of the link I use this line of code:
string keyImageName = Settings.Default.ServerUrl +
Settings.Default.KeyImagesFolder + relatedFinding.KeyImagePath;`
where KeyImageFolder is a virtual directory.
It works fine, but my problem is that the website has multiple Amazon instances, one for each geographical zone , so every time I deploy, I need to change the ip in the settings.it's annoying.
Is there a way to get the virtual directory's url, specifically for each machine?
if the JS is installed on the same machine as the server, does it really need a full path?
Many thanks

First, you'll need to get the physical path for the file or directory that you want to generate a url for. This can be done within a Page object using Request.ApplicationPath.
Next, this path can be converted to a url path using the Server.MapPath function. This will take into account if there are more than one websites tied to the same path in IIS.
var physicalPath = Path.Combine(Request.ApplicationPath, Settings.Default.KeyImagesFolder, relatedFinding.KeyImagePath);
var resourceUrl = Server.MapPath(physicalPath);

ASP physical and virtual path

This is the first time I make an asp site. This line of code is working fine on my pc but obviously to make it working on the production server I need to change the reference.
DirectoryInfo dir = new DirectoryInfo(#"C:\Users\Pink\Documents\Visual Studio 2012\Projects\ManagDoc_Framework\Test1_managDoc\Test1_managDoc\Allegati\" + recordIDcreateDir);
I have tried many sort of path combination but I am not getting it right.
I would like to find a solution that makes the code working on both pc, during development, and hosting server without having to change the code.
How should i write the path? Some help will be appreciated.

Use Server.MapPath method :
The MapPath method maps the specified relative or virtual path to the
corresponding physical directory on the server.
Additional details on W3schools.com, tutorial I followed, and where I learnt the existence of the above method.

C# Upload Files on another partition of the server

I'm using FileUpload.SaveAs() function of C# to upload files to the server but I want to save the files on another partition. Let us say, save the files on Drive D of the server instead on the current drive which is Drive C. Please share your thoughts. Thanks is advance.
I have learned that using full path such as
FileUpload.SaveAs("D:\FileUpload");
will save the file outside the web server.
Check this out.
To simplify the question, how can I upload files on the other partition of the server that hosts my web app?

Based on the documentation from http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.saveas.aspx, the String filename is the full path name of the location to save. Meaning you should be able to do so e.g:
FileUpload.SaveAs("D:\where_you_want_to_save")
By the way what have you tried and what error did you get?

Looking at the example on MSDN, it would appear that .SaveAs() accepts a fully qualified file name as a parameter. You could potentially use a Path object to cleanly build a path for the file, or just specify one directly as a string:
uploader.SaveAs("d:\\someFolder\\someFile.ext");

Resolved this by using Virtual Directory of IIS and providing admin credentials for authentication
