asp.net - How to escape string in .aspx -

I am trying to make this string work, I can not save it properly or I use wrong syntax I am "vs."

  & lt; A href = "& lt;% # string.format (" {0} items not irrelevant = truth and id = {1} ", page, & lt;% # container DataItem.Id)%> & gt; ... & lt; / A & gt;  

  & lt; A href = '& lt;% # string.format ("{0}? Item = true and id = {1}", page, container.datetime.id)%> & Gt; .. & lt; / A & gt;  

... everything is wrapped for reading power. It can all be alive in a row.
