C#.Net 3.0 features: Automatic Property

Microsoft introduced the new features in C#.Net 3.0 called Automatic Property.

No more need to declare the private variable for properties. It automatically creates the private variables for properties. But still you can use the conventional way of declaring the private variables to initialize the specific default value to private variable and also other calculation purposes.

Conventional Method:

class Customer
{
private long m_customerID;
private string m_name;

public string CustomerID
{
get
{
return m_customerID;
}
set
{
m_customerID = value;
}
}

public string Name
{
get
{
return m_name;
}
set
{
m_name = value;
}
}

}




C#.Net 3.0 New Method:

class Customer
{

public string CustomerID
{
get;
set;
}

public string Name
{
get;
set;
}

}


From the above declaration, you can find that the no private variable declared.


You may ask the question what would be default value for property. Here is the answer.

1. Value type = 0
2. Reference type = null
