问题
I couldn't seem to find an answer to this on the web.
Since C# is a compiled language, how is code inside a Razor view able to execute without the developer having to build again?
For example, if I load a page with this code: @{string test = "123";}.
But then change the code to this: @{string test = "test";}
How do I not need to rebuild? Also, is the thing that is allowing this to happen a C# feature or an MVC feature?
回答1:
The razor engine basically "compiles" the view. Something like this...
@model Person
<html>
<p>
@Model.FirstName
</p>
</html>
is actually compiled into a method in a class. I can't remember the exact functions it calls but it would look something along the lines of this:
class RazorPage<T>
{
T Model;
void Page
{
Write("<html>");
Write(" <p>");
Write(Model.FirstName);
Write(" </p>");
Write("</html>");
}
}
