The use of ``++[DefaultValue]++`` with ``++[Optional]++`` has no more effect than ``++[Optional]++`` alone. That's because ``++[DefaultValue]++`` doesn't actually do anything; it merely indicates the intent for the value. More than likely, ``++[DefaultValue]++`` was used in confusion instead of ``++[DefaultParameterValue]++``.


== Noncompliant Code Example

----
class MyClass
{
    public void DoStuff([Optional][DefaultValue(4)]int i, int j = 5)  // Noncompliant
    {
        Console.WriteLine(i);
    }

    public static void Main()
    {
        new MyClass().DoStuff(); // prints 0
    }
}
----


== Compliant Solution

----
class MyClass
{
    public void DoStuff([Optional][DefaultParameterValue(4)]int i, int j = 5) 
    {
        Console.WriteLine(i);
    }

    public static void Main()
    {
        new MyClass().DoStuff(); // prints 4
    }
}
