Can I initialize a C# attribute with an array or other variable number of arguments?

Question

Is it possible to create an attribute that can be initialized with a variable number of arguments?

For example:

[MyCustomAttribute(new int[3,4,5])]           


        

Answer 1

You can do that. Another example could be:

class MyAttribute: Attribute
{
    public MyAttribute(params object[] args)
    {
    }
}

[MyAttribute("hello", 2, 3.14f)]
class Program
{
    static void Main(string[] args)
    {
    }
}
