Get to know attribute

You can add declarative information to a program by using an attribute. An attribute defines additional information that is associated with a class, structure, method, and so on.

An attribute is supported by a class that inherits System.Attribute. All attribute classes must be subclasses of System.Attribute. This built-in attribute AttributeUsage specifies the types of items to which the attribute can be applied.

using System.Diagnostics;
/* j a v  a2 s  .c o  m*/

class MainClass
{
    [Conditional("DEBUG")]
    public void Validate()
    {
    }
}
