ASP.NET6 Blazor: Can a directory be mapped as a virtual subdirectory under wwwroot?-CodePudding

Can I map an arbitrary directory as a subdirectory of wwwroot? That is, the directory is not under wwwroot in the file system, but within my app, it is treated like so.

For example, I have created an ASP.NET 6.0 Blzor Server project. The programme dll path is in /app/proj1/BlazorApp1.dll. If there is an image at /app/proj1/wwwroot/images/dog.jpg, it can be rendered using <img src="images/dog.jpg"/> in my page. But what if I do not want to have this images directory actually under the wwwroot directory on the file system? Can the directory be somewhere else like /data/images, and I map that path to wwwroot/images, so that /data/images/dog.jpg can be rendered with <img src="images/dog.jpg"/> within my app?

There are 3 ways to do this that i know of, Firstly adjusting the settings, which is clearly documented on msdn, under the 'Serve files outside of web root' header;

app.UseStaticFiles(new StaticFileOptions
{
    FileProvider = new PhysicalFileProvider(
           Path.Combine(builder.Environment.ContentRootPath, "MyStaticFiles")),
    RequestPath = "/StaticFiles"
});
