@if, else if, else

@if controls when code runs; else and else if do not require the @ symbol:

@if (value % 2 == 0)
{
    <p>The value was even.</p>
}
else if (value >= 1337)
{
    <p>The value is large.</p>
}
else
{
    <p>The value is odd and small.</p>
}

@switch Statements

Like so:

@switch (value)
{
    case 1:
        <p>The value is 1!</p>
        break;
    case 1337:
        <p>Your number is 1337!</p>
        break;
    default:
        <p>Your number wasn't 1 or 1337.</p>
        break;
}

@for, @foreach, @while, and @do while

Templated HTML can be rendered in looping control statements:

@{
    var people = new Person[]
    {
          new Person("Weston", 33),
          new Person("Johnathon", 41),
          ...
    };
}

Foreach example:

@foreach (var person in people)
{
    <p>Name: @person.Name</p>
    <p>Age: @person.Age</p>
}

Compound @using

In Razor, a @using statement is used to create HTML Helpers that contain additional content, like this one that renders a <form> tag:

@using (Html.BeginForm())
{
    <div>
        Email: <input type="email" id="Email" value="">
        <button>Register</button>
    </div>
}

@try, catch, finally

Like C#:

@try
{
    throw new InvalidOperationException("You did something invalid.");
}
catch (Exception ex)
{
    <p>The exception message: @ex.Message</p>
}
finally
{
    <p>The finally statement.</p>
}

@lock

Like so:

@lock (SomeLock)
{
    // Do critical section work
}
