How do I convert an HttpRequest into an HttpRequestBase object?

Question

My problem is the opposite of this: How do I convert an HttpRequestBase into an HttpRequest object?

In my ASP.NET MVC application I have a method used by many controlle

Answer 1

In my application I had calls coming from several different places that needed access to the HttpRequestBase. I created this set of extension methods to get and convert from several different Http types into a HttpRequestBase, then used HttpRequestBase as the base type for interface and class methods through the application when I needed access to the request.

public static class RequestExtensions
{
    public static HttpRequestBase GetHttpRequestBase(this HttpContext httpContext)
    {
        if (httpContext == null)
        {
            throw new ArgumentException("Context is null.");
        }

        return httpContext.Request.ToHttpRequestBase();
    }

    public static HttpRequestBase GetHttpRequestBase(this HttpRequestMessage httpRequestMessage)
    {
        if (httpRequestMessage == null)
        {
            throw new ArgumentException("Request message is null.");
        }

        HttpContextWrapper context = null;
        if (httpRequestMessage.Properties.ContainsKey("MS_HttpContext"))
        {
            context = httpRequestMessage.Properties["MS_HttpContext"] as HttpContextWrapper;
        }
        if (context == null)
        {
            throw new ArgumentException("Context is null.");
        }

        return context.Request;
    }

    public static HttpRequestBase GetHttpRequestBase(this HttpApplication httpApplication)
    {
        if (httpApplication == null)
        {
            throw new ArgumentException("Application is null.");
        }

        return httpApplication.Request.ToHttpRequestBase();
    }

    public static HttpRequestBase ToHttpRequestBase(this HttpRequest httpRequest)
    {
        if (httpRequest == null)
        {
            throw new ArgumentException("Request is null.");
        }

        return new HttpRequestWrapper(httpRequest);
    }
}

I came across several SO answers that helped me build these extensions:
