Object and Collection Initializers (C#)
October 31, 2009 Leave a comment
C# 3.0 was released as a part of the Microsoft .NET 3.5 Framework. In this blog post, I’ll cover the object and collection intitializers feature of C# 3.0. Initializers introduce a concise syntax that combines object creation and initialization in a single step. It even allows for parentheses to be optional for paramaterless constructors as shown below:
Point p = new Point {
X=3,
Y=99 };
Employee myEmployee = new Employee() {
Name = "John Doe",
Position = "Marketing Manager",
Department = "Marketing" };
Name = "John Doe",
Position = "Marketing Manager",
Department = "Marketing" };
Initializers work very well with constructors as shown below:. The following code snippet shows an instance where a parameterized constructor is called along with remaining properties initialized.
class Customer
{
public Customer(string customerKey) { … }
public string CustomerKey { get { … } }
public string ContactName { get; set; }
public string City { get; set; }
}
{
public Customer(string customerKey) { … }
public string CustomerKey { get { … } }
public string ContactName { get; set; }
public string City { get; set; }
}
var c = new Customer("MARKS") {
ContactName = "Mark Strawmyer",
City = "Indianapolis"
}
ContactName = "Mark Strawmyer",
City = "Indianapolis"
}
