The version 3 of C# brings us a lot of syntactic sugar to reduce the length of our code. Here are some of them.
This post is part of a serie about making C# code shorter.
- Part 1 : Extension methods and Linq
- Part 2 : Try Catch and reusability
- Part 3 : C# 3 shortcuts
- Part 4 : Chainable methods
- Part 5 : Parsing and conversion
- Part 6 : Contructor with initializer and event setters
- Part 7 : Post compilation
Constructors with Property initializers
-
//Verbose and Ugly
-
Post value = new Post();
-
value.Title = "New Version For C#";
-
value.CreatedOn = DateTime.Now;
-
CreatePost(value);
-
-
//Concise and Sweet
-
CreatePost(new Post
-
{
-
Title = "NewVersion For C#",
-
CreatedOn = DateTime.Now
-
});
Collection initializers
-
//Verbose and Ugly
-
var names = new List<string>();
-
names.Add("manitra");
-
names.Add("yeah");
-
SaveNames(names);
-
-
//Concise and Sweet
-
SaveNames(new List<string> { "manitra", "yeah" });
Var keyword
-
//Verbose and Ugly
-
Dictionary<string, List<Post>> result = new Dictionary<string, List<Post>>();
-
-
//Concise and Sweet (But still strongly typed)
-
var result = new Dictionary<string, List<Post>>();
Automatic properties
-
//Verbose and Ugly
-
public class Post
-
{
-
private string title;
-
private string description;
-
private DateTime createdOn;
-
-
public string Title
-
{
-
get
-
{
-
return this.title;
-
}
-
set
-
{
-
this.title = value;
-
}
-
}
-
-
public string Description
-
{
-
get
-
{
-
return this.description;
-
}
-
set
-
{
-
this.description = value;
-
}
-
}
-
-
public System.DateTime CreatedOn
-
{
-
get
-
{
-
return this.createdOn;
-
}
-
set
-
{
-
this.createdOn = value;
-
}
-
}
-
}
-
-
//Concise and Sweet
-
public class Post
-
{
-
public string Title { get; set; }
-
public string Description { get; set; }
-
public DateTime CreatedOn { get; set; }
-
}
