How do you include .html or .asp file using razor?

Question

Is it possible to use server side include in Razor view engine to include .html or .asp file? We have an .html file and .asp files that contain website menus that are used

Answer 1

you can include server side code and aspx file in .cshtml files as below and then inlude classic asp files or html files. Here are the steps

1. Index.cshtml

@Html.RenderPartial("InsertASPCodeHelper")

2.InsertASPCodeHelper.aspx

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<!--#include VIRTUAL="~/Views/Shared/Header.aspx"-->

3. Header.aspx

<!--#include file="/header/header.inc"-->

Answer 2

Try implementing this HTML helper:

public static IHtmlString ServerSideInclude(this HtmlHelper helper, string serverPath)
{
    var filePath = HttpContext.Current.Server.MapPath(serverPath);

    // load from file
    using (var streamReader = File.OpenText(filePath))
    {
        var markup = streamReader.ReadToEnd();
        return new HtmlString(markup);
    }
}

or:

public static IHtmlString ServerSideInclude(this HtmlHelper helper, string serverPath)
{
    var filePath = HttpContext.Current.Server.MapPath(serverPath);

    var markup = File.ReadAllText(filePath);
    return new HtmlString(markup);
}

Sorry guys for bit old answer but I found some way to attach asp file with razor. Of course you need to do some trick but it works! First of all I created .NET MVC 3 application.

In my _Layout.cshtml I added following line:

@Html.Partial("InsertHelper")

Then I created InsertHelper.aspx in my Shared folder with this content:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>

<!--#include VIRTUAL="/ViewPage1.aspx"-->

ViewPage1.aspx is locaited in my root directory, and has just simple if to check whether it works:

<%
string dummy;
dummy="nz";
%>

<% if (dummy == "nz") { %>
nz indeed
<% } else { %>
not nz
<% } %>

And it works!

Razor is able to render partials with different ViewEngine, and that's why this example is working.

And one more thing: remember to not add following line in both aspx files:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>

You can add it only once! Hope it helps!

@Html.Raw(File.ReadAllText(Server.MapPath("~/content/somefile.css")))

Html.Include(relativeVirtualPath) Extension Method

I wanted to include files like this for documentation purposes (putting the contents of a file in a <pre> tag).

To do this I added an HtmlHelperExtension with a method that takes a relative virtual path (doesn't have to be an absolute virtual path) and an optional boolean to indicate whether you wish to html encode the contents, which by default my method does since I'm using it primarily for showing code.

The real key to getting this code to work was using the VirtualPathUtility as well as the WebPageBase. Sample:

// Assume we are dealing with Razor as WebPageBase is the base page for razor.
// Making this assumption we can get the virtual path of the view currently
// executing (will return partial view virtual path or primary view virtual
// path just depending on what is executing).
var virtualDirectory = VirtualPathUtility.GetDirectory(
   ((WebPageBase)htmlHelper.ViewDataContainer).VirtualPath);

Full HtmlHelperExtension Code:

public static class HtmlHelperExtensions
{
    private static readonly IEnumerable<string> IncludeFileSupportedExtensions = new String[]
    {
        ".resource",
        ".cshtml",
        ".vbhtml",
    };

    public static IHtmlString IncludeFile(
       this HtmlHelper htmlHelper, 
       string virtualFilePath, 
       bool htmlEncode = true)
    {
        var virtualDirectory = VirtualPathUtility.GetDirectory(
            ((WebPageBase)htmlHelper.ViewDataContainer).VirtualPath);
        var fullVirtualPath = VirtualPathUtility.Combine(
            virtualDirectory, virtualFilePath);
        var filePath = htmlHelper.ViewContext.HttpContext.Server.MapPath(
            fullVirtualPath);

        if (File.Exists(filePath))
        {
            return GetHtmlString(File.ReadAllText(filePath), htmlEncode);
        }
        foreach (var includeFileExtension in IncludeFileSupportedExtensions)
        {
            var filePathWithExtension = filePath + includeFileExtension;
            if (File.Exists(filePathWithExtension))
            {
                return GetHtmlString(File.ReadAllText(filePathWithExtension), htmlEncode);
            }
        }
        throw new ArgumentException(string.Format(
@"Could not find path for ""{0}"".
Virtual Directory: ""{1}""
Full Virtual Path: ""{2}""
File Path: ""{3}""",
                    virtualFilePath, virtualDirectory, fullVirtualPath, filePath));
    }

    private static IHtmlString GetHtmlString(string str, bool htmlEncode)
    {
        return htmlEncode
            ? new HtmlString(HttpUtility.HtmlEncode(str))
            : new HtmlString(str);
    }
}

Just do:

@Html.Partial("_SliderPartial")

while "_SliderPartial" is your "_SliderPartial.cshtml" file and your fine.
