Insert Html.RenderAction("CartSummary", "ShoppingCart") To Dynamic String ?

Question

I have dynamic strings, for example

"hello bold italic {0} xxx {0}yyy {0} etc...",

"abcd {0} how to xyz {0} newline {0}..etc..."

and more

How to insert <% Html.RenderAction("CartSummary", "ShoppingCart"); %> to the dynamic string at the {0} position?

Thank You.

Html.RenderAction writes directly to the response. You could use Html.Action which returns an MvcHtmlString.
