Howto render a Func<Object, TemplateWriter> to string in Razor view engine Html Helper?
I am not actually using the Razor from ASP.NET MVC, I am using the standalone version as found here
I have created my own HtmlHelper as described here
I have determined via trial and error that razor <text>
attributes produce a Func<Object, TemplateWriter>
object when called in the context of a method.
The method signature of the helper looks like:
public String IncludeOnce(Func<Object, TemplateWriter> text) {
//here I need to be able to render the text Func to a string so
//I can do some checks, and return it if it hasnt yet been included
//or return an empty str开发者_开发技巧ing if it has
}
I am invoking it in my template like:
@Html.IncludeOnce(
@<text>
<style type="text/css">
/* styles I only want on the page once, and not everytime the template
is rendered. Note: I need @Model to work here too*/
.something { top: @Model.Top }
</style>
</text>)
How can I get it as a String? Also, If I pass it to another template, eg:
public String IncludeOnce(Func<Object, TemplateWriter> text) {
return Razor.Parse("other.cshtml", new { Content = text(new Object()) })
}
where other.cshtml
is:
@Model.Content
it works. What does Razor.Parse know that I dont?
Thanks!
I'm assuming the Object parameter is the Model. So, by looking at your code above, I'm pretty sure the following will work:
public String IncludeOnce(Func<Object, TemplateWriter> text) {
string output = text(Model).ToString();
//Do Stuff
return output
}
