Shortcuts in .Net 2010

Hai Friends,

This is article which is very useful in day-to-day coding implementation for those who are in Microsoft .Net technology and using Visual studio for their development.

This article contains all the shortcuts which can be used while writing the code in .Net. It includes all the shortcuts which can really increase the utilization of the resource and can improve the performance.

Now you don’t need to remember all the syntax which is required to write the loops, properties, events, delegates, dependency properties etc.

So use this resource and improve the productivity.

3 small things in C# code

1. Null Coalescing Operator (??)

A new operator can be used which can be shortcut of ternary operator to check the null value:

Ternary operator (?:):
string empName = (value != null) ? value : string.Empty;
we can write it using null-coalescing operator (??):
string empName = value ?? string.Empty;

2. The As Cast
we might have seen the code something like:
if (customer is DeluxCustomer)
{
var dCust = (DeluxCustomer)customer
// ...
}
This is redundant because we are checking the type twice. Once in the is check and once in the cast.
We can use as operator in place. This will cast the type if the types are compatible, or return null if not:
var dCust = customer as DeluxCustomer;
// ... we can write if condition to check for null
}
we can avoid double-checking the type.
3. Auto-Properties
This is the new concept to define the properties in C#: we can define the auto-property without much code:
public class Employee
{
public int ID { get; set; }
public string name { get; set; }
}
