You should inject IHostingEnvironment so you can get the web root (wwwroot by default) location.

public class HomeController : Controller
{
    private readonly IHostingEnvironment hostingEnvironment;
    public HomeController(IHostingEnvironment environment)
    {
        hostingEnvironment = environment;
    }
    [HttpPost]
    public async Task UploadFiles(List files)
    {
        long size = files.Sum(f => f.Length);

        // full path to file in temp location
        var filePath = Path.GetTempFileName();

        foreach (var formFile in files)
        {
            var uploads = Path.Combine(hostingEnvironment.WebRootPath, "images");
            var fullPath = Path.Combine(uploads, GetUniqueFileName(formFile.FileName));
            formFile.CopyTo(new FileStream(fullPath, FileMode.Create));

        }
        return Ok(new { count = files.Count, size, filePath });
    }
    private string GetUniqueFileName(string fileName)
    {
        fileName = Path.GetFileName(fileName);
        return  Path.GetFileNameWithoutExtension(fileName)
                  + "_" 
                  + Guid.NewGuid().ToString().Substring(0, 4) 
                  + Path.GetExtension(fileName);
    }
}

This will save the files to the images directory in wwwroot.

Make sure that your form tag's action attribute is set to the UploadFiles action method of HomeController(/Home/UploadFiles)

    

        

            
Upload one or more files using this form:
            
        
    
    

        

            
        
    

I am not very certain why you want to return Ok result from this. You may probably return a redirect result to the listing page.
