Default keyword in c#

In this post, I am going to explain about default keyword in c#.

Introduction:As per MSDN default keyword in C# used to assign the default value of the type. In some situation its comes very handy where we don’t want to create object and directly assign the default value of it.

The basic syntax of default is default(T) where t is any reference type of value type and If T is a value type, whether it will be  a numeric value or struct.

Default Keyword usage:We can use Default keyword in variety of cases.

Assigning value to nullable Type:

ASP.NET Friendly URLs – Cleaner, SEO friendly URLs

Search Engine optimization is one of the key factor for your site. If you spend millions of dollars on making your website looks good and bug free then also its possible that you will not get attention of search engine because of your URLs.  For example you’re having shopping cart created in asp.net and you have not optimized your URL then it will look like following.

www.foo.com ?Product.aspx?Category=1& Page=1

If you search engine read this URL then search engine will not know much about this URLs. Even normal people  who does not know querystring menaing(?Category=watch&Page=1) will not understand it. But If you have URL like following.

www.foo.com/prduct/category/watch/page/1

It’s easy to read and search engine and normal people will know that you are loading products that belongs to category watch and this is a first page.

public class Address { public string Street { get; set; } public string PostalCode { get; set; } }
