Tip: How to shorten your C# code?

Some of the new features in C# 3.0 allow you to write shorter code that is easier to read and maintain. The following code couples have the same results.

• Short syntax for object initialization initialization.

  C#

   

  ObjectType objectName = new ObjectType();

  objectName.PropertyName = newValue;

  objectName.PropertyName2 = newValue2;

   

  C#

  ObjectType objectName = new ObjectType(){ PropertyName = newValue, PropertyName2 = newValue2 };

• Syntaxt for anonymous types

C#

SomeVeryLongNameOfType objectName = new SomeVeryLongNameOfType();

C#

var objectName = SomeVeryLongNameOfType();

• Short syntax for collection initialization

C#

CollectionType collectionName = new CollectionType();

collectionName.Add( newItem1 );

..

collectionName.Add( newItemN );

C#

CollectionType collectionName = new CollectionType() { Item1,...,ItemN };

That's it!
