How to create a custom attribute in a property and access by Reflection [duplicate]

This question already has an answer here:

• C# Reflection : Finding Custom Attributes on a Class Property 2 answers

I have a property like this:

[Category("Appearance"),
 DisplayName("CustomColor"),
 DescriptionAttribute("Custom background color")]
public int BackgroundColorIndex
{
    get;
    set;
}

I want to create a custom string attribute, like DisplayName and then access its value using Reflection. Is it possible? How could I do something like this?
