Is it possible to have multiple layout pages in a C# razor application?

Question

Previously I have created C# applications using MVC and it is possible to specify the layout view to use on the view in it's file. Such that the view file contains:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

/*Rest of file*/

Recently I have started creating applications using razor pages. So far I only have a single layout page. However, I would like to use a different layout page for a subset of pages, and I can only see how to specify a single layout page for all pages within the Pages folder. As the layout is declared in the _ViewStart.cshtml file. Where the contents of this file is simply:

@{
    Layout = "_Layout";
}

Is there a way of using one layout file for some pages, and then a different layout files for other pages?

Answer 1

If you want to using one layout file for some pages, and then a different layout files for other pages.you can try to get the current url in _ViewStart.cshtml,then check the url and set Layout page.Here is a demo:

_ViewStart.cshtml(Page1 and Page2 will set Layout = "_Layout";,and the other page will set Layout = "_Layout1";):

@{
    var routeUrl = ViewContext.RouteData.Values["Page"].ToString();
    //you can put pages' name into pages
    var pages = new List<string> { "Page1", "Page2"};
    //if routeUrl contains any of pages,the page will use _Layout as Layout page,the other pages will use _Layout1 ad Layout page
    if (pages.Any(routeUrl.Contains))
    {
        Layout = "_Layout";
    }
    else {
        Layout = "_Layout1";
    }

}

result:

Also,you can use

@{
   Layout="xxx"
}

to set diiferent layout in different pages as David Tansey said.
