Function inside .cshtml page
@functions{
public string GetSomeString(){
return string.Empty;
}
}
<h2>index</h2>
@GetSomeString()
Helper inside .cshtml page
@helper WelcomeMessage(string username)
{
<p>Welcome, @username.</p>
}
Then you invoke it like this:
@WelcomeMessage("some username")
If your method doesn't have to return html and has to do something else then you can use a lambda instead of helper method in Razor
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
Func<int,int,int> Sum = (a, b) => a + b;
}
<h2>Index</h2>
@Sum(3,4)
