This works, because it returns the result of partial view rendering in a string:

@Html.Partial("Path/to/my/partial/view")

But I prefer to use RenderPartial and it seems I need to write:

@{Html.RenderPartial("Path/to/my/partial/view");}

instead of:

@Html.RenderPartial("Path/to/my/partial/view");

To get it to work. Error message:

 Compiler Error Message: CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments

If there any better way instead of opening code block @{...} just for one method call?

  • RenderPartial() is a void method that writes to the response stream. A void method, in C#, needs a ; and hence must be enclosed by { }.

  • Partial() is a method that returns an MvcHtmlString. In Razor, You can call a property or a method that returns such a string with just a @ prefix to distinguish it from plain HTML you have on the page.
