.Net 6 IWebHostENvironment returns local path that exists on server

Question

I have a .net core web api deployed on smarter ASP.net services, in my web api I save images and files by adding them to a predefined folder in wwwroot file that exists in the presistance project, and then i save the url in SQL database. This is my code to save the file and get the url using IWebHostEnvironment, after sending the request the saved url is like this "h:\root\home\siteurl\OriginalForms\MySavedFile", This is the path for the file on the server itself, i want to save the url itself like "http://MyDomain//Folder//File" not the local one on the server.

MyCode : var path = Path.Combine(_webHostEnvironment.WebRootPath "OriginalForms",request.FormName); using (FileStream stream = new FileStream(path, FileMode.Create)) { await request.Form.CopyToAsync(stream,cancellationToken); } OriginalForm.Url = path

Hi @Abdelrahman Tarek ,

You should build the file path by yourself. Refer to the following sample:

        var foldername = "images";  
        var filename = "Image1.png";  
        var path1 = Path.Combine(_environment.WebRootPath, foldername, filename);  
        var path2 = Path.Combine("\\", foldername, filename);   
        var location = new Uri($"{Request.Scheme}://{Request.Host}/{foldername}/{filename}");   
        var url = location.AbsoluteUri;   

If you want to upload/download file from the wwwroot folder, you can get the file path via the IWebHostENvironment.

If you want to display the image using image control, you can use the relative paths, such as path2 in the above sample.

If you want to store the file path using the request host, directly build the request url, like the path3:

The result as below:
