In ASP.NET MVC 3
I wanted to write a function in the "Home controller" returns a string,
For example:

public string ABC (int id)
{
string x = ...
....
....
return x;
}

Now, in the Index page, the beginning, it always call the ABC and result to the screen.
Imagine how it is like to use the WinForm that timer_ticks
