Lazy Loading

Not to load code modules into memory until you are sure you are going to be required. Example:

I am having Category and Sub-Category. Category can hold list of Sub-Category, but this sub-category is not require every time. I’ll load sub-category when it is required. I am using following code to achieve this.

public class Category

{

// Other Geter Seter..

private List<SubCategory> _subCategories;

/// <summary>

/// Sub Categories

/// </summary>

public List<SubCategory> SubCategories

{

get

{

//Lazy Load

if (_subCategories == null)

_subCategories = GetSubCategories(this.ID);

return _subCategories;

}

set { _subCategories = value; }

}

I’ll not fill list of sub-category in default load of Category object (cunstructor or some Load method) instant of I’ll load list of sub-category when it is acthuly required.
