Vici MVC Quick Walkthrough - Part 3 - Conditionals

What if you want to show some information depending on a specific condition? This is possible by using the  directives in your template.

Again, we will use our original class:

[Layout("master")] 
[View("home")]
public class Home : PageController
{
   public class Employee
   {
       public Employee(string name, decimal salary) { Name = name; Salary = salary; }
 
       public string Name;
       public decimal Salary;
   }
 
   public void Run()
   {
      List<Employee> employees = new List<Employee>();
 
      employees.Add( new Employee("Mark Jones" , 65000) );
      employees.Add( new Employee("John Doe" , 244000) );
      employees.Add( new Employee("Phil Baxter" , 125000) );
 
      ViewData["Employees"] = employees;
   }
}

<html>
<body>
<table>
  <tr><th>Name</th><th>Salary</th></tr><th>&nbsp;</th>
  <!--{{ foreach employee in Employees }}-->
    <tr>
       <td>{{employee.Name}}</td>
       <td>{{employee.Salary}}</td>
       <td><!--{{ if employee.Salary > 200000 }}-->Rich Guy!<!--{{ endif }}--></td></tr>
  <!--{{ endfor }}-->
</table>
<p>There are {{ Employees.Count }} employees</p>
</body>
</html>

The resulting HTML output:

Name	Salary
Mark Jones	65000
John Doe	244000	Rich Guy!
Phil Baxter	125000

There are 3 employees
