So none of the ones listed here worked for me, but using a few of the answers, I got something working:
public string GetBaseUrl()
{
var request = HttpContext.Current.Request;
var appUrl = HttpRuntime.AppDomainAppVirtualPath;
if (appUrl != "/")
appUrl = "/" + appUrl;
var baseUrl = string.Format("{0}://{1}{2}", request.Url.Scheme, request.Url.Authority, appUrl);
return baseUrl;
}
Update for ASP.NET Core / MVC 6:
ASP.NET Core makes this process a bit more painful, especially if you are deep in your code. You have 2 options to get at the HttpContext
1) Pass it in from your controller:
var model = new MyClass(HttpContext);
then in model:
private HttpContext currentContext;
public MyClass(HttpContext currentContext)
{
this.currentContext = currentContext;
}
2) Perhaps the cleaner way is to inject it into your class, which starts with registering the types in your Startup:
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
services.AddTransient<MyClass, MyClass>();
services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}
then have it injected for you like this:
private HttpContext currentContext;
public MyClass(IHttpContextAccessor httpContextAccessor)
{
currentContext = httpContextAccessor.HttpContext;
}
in either case, here is the updated for .NET Core GetBaseUrl():
public string GetBaseUrl()
{
var request = currentContext.Request;
var host = request.Host.ToUriComponent();
var pathBase = request.PathBase.ToUriComponent();
return $"{request.Scheme}://{host}{pathBase}";
}
