IsDefault extension

Known reserved word of C#  default(TYPE)  can be used as very usability feature as IsDefault():

public static bool IsDefault<T>(this T value)

{

    return value == null || value.Equals(default(T));

}

A can be available in every place in the project by next using:

int number = 5;

if (number.IsDefault())

{

    //...

}

It's  short and simple alternative to usual:

if (number == default(int)) 

The extension work nice with objects:

class Foo

{

    public int Id { get; set; }

    public int Name { get; set; }

}

//...

Foo foo = new Foo();

if (!foo.IsDefault())

{

    //....

    foo.Name = "John Smith";

}

 Enjoy!
